## 0. Purpose and Scope
|
||||||
|
|
||||||
|
This document is an internal schema instrument. It is not a scenario.
|
||||||
|
It is not player-facing content. It will not be shown to participants.
|
||||||
|
|
||||||
|
Its purpose is to map the parameter domains required for an economically
|
||||||
|
honest simulation of Roman commercial life in approximately 14 BCE. Four
|
||||||
|
domains are covered:
|
||||||
|
|
||||||
|
1. Enslaved labour
|
||||||
|
2. Legal and status discrimination
|
||||||
|
3. Commercial sex
|
||||||
|
4. Public violence and the arena
|
||||||
|
|
||||||
|
These domains are not peripheral to Roman economic life. They are structural.
|
||||||
|
A simulation that excludes them cannot model Roman economics accurately.
|
||||||
|
A simulation that includes them as gratuitous spectacle has failed its purpose.
|
||||||
|
|
||||||
|
**The principle governing this document:**
|
||||||
|
|
||||||
|
These domains are modelled as parameters and economic forces. The simulation
|
||||||
|
does not editorialise. It models. The participant encounters these as the
|
||||||
|
MERCATOR encounters them — as the texture of the world they operate in,
|
||||||
|
not as moral choices presented for approval. The facts no longer affect
|
||||||
|
living beings. They belong to a historical period whose actors have all
|
||||||
|
ceased to exist. The purpose of modelling them is contribution to accurate
|
||||||
|
historical understanding, not sensation.
|
||||||
|
|
||||||
|
**Method:** for each domain, this document identifies:
|
||||||
|
- The structural role of the domain in the Roman economy
|
||||||
|
- Existing parameters from `docs/architecture/parameter-registry.md` that
|
||||||
|
are already affected by this domain, with the nature of the effect stated
|
||||||
|
- New parameters required that are not yet in the registry
|
||||||
|

## 1. Enslaved Labour
|
||||||
|
|
||||||
|
### 1.1 Structural role
|
||||||
|
|
||||||
|
Slavery was not an anomaly in the Roman economy. It was its operating
|
||||||
|
system. Estimates suggest enslaved persons constituted 15–30% of the
|
||||||
|
Italian population in the late Republic and early Empire — potentially
|
||||||
|
2–3 million people in Italy alone. In the commercial harbour economy of
|
||||||
|
Ostia, enslaved labour was present at every operational level: BAIВLVS
|
||||||
|
(porters), warehouse workers, ship crew members, accounting staff,
|
||||||
|
household service, and skilled artisans.
|
||||||
|
|
||||||
|
The MERCATOR operated inside this system whether or not he personally
|
||||||
|
owned enslaved persons. He hired them, contracted their labour through
|
||||||
|
their owners, competed against their output, and used infrastructure
|
||||||
|
they maintained. His FACTOR might be enslaved or freedman. His access
|
||||||
|
to certain services depended on this system.
|
||||||
|
|
||||||
|
The Roman economy did not develop water-powered or steam-powered
|
||||||
|
industrial production at scale despite possessing the engineering
|
||||||
|
knowledge to do so. The reason is documented: human bodies were cheaper.
|
||||||
|
This is not an inference — it is the economic consequence of a labour
|
||||||
|
cost structure where the marginal cost of additional enslaved labour
|
||||||
|
was lower than the capital cost of mechanical substitution. This
|
||||||
|
consequence must be present in the parameter model.

||||||

||||||

||||||
|
### 1.2 Existing parameters affected
|
||||||
|
|
||||||
|
**`liquiditas`**
|
||||||
|
A MERCATOR who owns enslaved workers holds capital in a non-liquid form.
|
||||||
|
Their sale value is an asset; their maintenance is a recurring cost.
|
||||||
|
The ratio of enslaved-to-hired labour in a commercial operation directly
|
||||||
|
affects the owner's liquidity profile. The existing `liquiditas` parameter
|
||||||
|
must accommodate a distinction between liquid capital and capital held in
|
||||||
|
human assets.
|
||||||
|
|
||||||
|
**`labour_cost` (stub — see §1.3)**
|
||||||
|
Currently absent from the registry. Hired free labour (MERCENNARIUS)
|
||||||
|
and contracted enslaved labour have different cost structures, different
|
||||||
|
legal exposure for the contracting party, and different reliability
|
||||||
|
profiles. These cannot be collapsed into a single cost parameter.
|
||||||
|
|
||||||
|
**`ius_accessus`**
|
||||||
|
An enslaved person has no IVS_ACCESSVS in Roman law. They cannot
|
||||||
|
enter contracts, appear as witnesses, or initiate legal proceedings
|
||||||
|
in their own name. A MERCATOR conducting NEGOTIA through an enslaved
|
||||||
|
FACTOR (institor servilis) has a specific legal exposure profile:
|
||||||
|
the owner is liable for the FACTOR's commercial acts up to the value
|
||||||
|
of the PECULIUM (the allowance granted to the enslaved person for
|
||||||
|
commercial use). This is the *actio institoria* and *actio tributoria*
|
||||||
|
framework. The `ius_accessus` differential between a CIVIS, a LIBERTUS,
|
||||||
|
and a SERVUS is not a single ordinal scale — it is a legally structured
|
||||||
|
set of distinct capabilities and incapacities.
|
||||||
|
|
||||||
|
**`auctoritas`**
|
||||||
|
A MERCATOR who treats enslaved persons visibly well or badly affects
|
||||||
|
their AVCTORITAS differently depending on the social context. Excessive
|
||||||
|
cruelty was considered poor form even in a slave-owning society —
|
||||||
|
not on humanitarian grounds, but because it signalled poor management
|
||||||
|
and social instability. The AVCTORITAS system must accommodate the
|
||||||
|
social signalling dimension of how an actor manages labour.
|
||||||
|
|
||||||
|
**`officia_burden`**
|
||||||
|
Ownership of enslaved persons creates legal obligations (maintenance,
|
||||||
|
the *actio de peculio*, liability for their commercial acts) that
|
||||||
|
contribute to OFFICIA_BVRDEN. This is not modelled in the current
|
||||||
|
registry entry, which frames OFFICIA_BVRDEN primarily in terms of
|
||||||
|
social obligations.
|
||||||
|
|
||||||
|
### 1.3 New parameters required
|
||||||
|
|
||||||
|
**`labour_source`**
|
||||||
|
```
|
||||||
|
token: labour_source
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: research_needed
|
||||||
|
```
|
||||||
|
The composition of an actor's labour force: proportion enslaved vs
|
||||||
|
free hired vs freedman contracted. Affects `liquiditas` profile,
|
||||||
|
`ius_accessus` exposure, legal liability, and operational flexibility.
|
||||||
|
An actor with primarily enslaved labour has lower variable costs but
|
||||||
|
higher capital locked in assets and higher legal exposure for their
|
||||||
|
acts. An actor with primarily hired free labour has higher variable
|
||||||
|
costs, lower asset lock, and cleaner legal separation.
|
||||||
|
|
||||||
|
**`labour_cost`**
|
||||||
|
```
|
||||||
|
token: labour_cost
|
||||||
|
scope: scenario
|
||||||
|
layer: roman
|
||||||
|
maturity: research_needed
|
||||||
|
```
|
||||||
|
The cost per unit of labour for a specific ITER or operational task,
|
||||||
|
disaggregated by labour type. BAIВLVS day rate for free hired labour
|
||||||
|
is documented in Diocletian's Edict (301 CE, later than our period but
|
||||||
|
provides relative structure). Earlier estimates require interpolation
|
||||||
|
from Cato and Columella. Research needed: Ostia-specific rates,
|
||||||
|
1st c. BCE.
|
||||||
|
|
||||||
|
**`peculium_value`**
|
||||||
|
```
|
||||||
|
token: peculium_value
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: research_needed
|
||||||
|
```
|
||||||
|
The commercial allowance granted to an enslaved FACTOR for use in
|
||||||
|
NEGOTIA. Sets the ceiling of the owner's liability under *actio
|
||||||
|
tributoria*. Also the de facto working capital of an enslaved
|
||||||
|
commercial agent. A FACTOR with a large PECULIUM is effectively
|
||||||
|
conducting independent commercial operations on behalf of their owner.
|
||||||
|
This is one of the mechanisms by which enslaved persons could
|
||||||
|
accumulate capital toward self-purchase (MANUMISSIO).
|
||||||
|
|
||||||
|
**`manumission_probability`**
|
||||||
|
```
|
||||||
|
token: manumission_probability
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: research_needed
|
||||||
|
```
|
||||||
|
The probability that a skilled enslaved commercial agent will be
|
||||||
|
formally freed (MANUMISSIO) within a defined time horizon, converting
|
||||||
|
to LIBERTUS status. Relevant because LIBERTUS actors have a different
|
||||||
|
parameter profile from both CIVIS and SERVUS actors. The transition
|
||||||
|
from SERVUS to LIBERTUS is a background drift event of the highest
|
||||||
|
magnitude — it changes IVS_ACCESSVS, AVCTORITAS floor, and social
|
||||||
|
network access simultaneously. This transition is the origin story of
|
||||||
|
the BACKGROUND-0002 (Freedman Trader) cast profile.

## 2. Legal and Status Discrimination
|
||||||
|
|
||||||
|
### 2.1 Structural role
|
||||||
|
|
||||||
|
Roman society was organised around legally encoded status hierarchies
|
||||||
|
that directly governed commercial capability. These were not informal
|
||||||
|
prejudices — they were written into law and enforced by courts. The
|
||||||
|
relevant distinctions for the MERCATOR's world:
|
||||||
|
|
||||||
|
**CIVIS ROMANVS** — full Roman citizen. Full legal capability: contract,
|
||||||
|
witness, property ownership, legal action. The baseline.
|
||||||
|
|
||||||
|
**LATINVS** — Latin status. Commercial rights but restricted political
|
||||||
|
and full legal rights. Many LIBERTI were LATINI IVNIANI — freed but
|
||||||
|
without full citizenship.
|
||||||
|
|
||||||
|
**PEREGRINUS** — foreign free person. Commercial activity permitted
|
||||||
|
under *ius gentium* but restricted Roman law access. Significant in
|
||||||
|
Ostia, a port city with large foreign populations.
|
||||||
|
|
||||||
|
**LIBERTUS / LIBERTA** — freedman/woman. Citizen status in most cases
|
||||||
|
(if freed formally by a CIVIS) but socially marked by servile origin.
|
||||||
|
Could not hold most public offices. Subject to ongoing *operae* (labour
|
||||||
|
obligations) to former owner. In practice, freedmen dominated Roman
|
||||||
|
commercial and craft activity.
|
||||||
|
|
||||||
|
**SERVUS** — enslaved person. No legal personhood. No contract, no
|
||||||
|
witness, no property (technically — PECULIUM was a practical workaround).
|
||||||
|
|
||||||
|
**Women** — regardless of status, Roman women had restricted commercial
|
||||||
|
legal capability without a male guardian (TVTOR) in most circumstances.
|
||||||
|
Exceptions existed; they were exceptions.
|
||||||
|
|
||||||
|
**Non-Roman ethnic and religious communities** — Jews, Egyptians, and
|
||||||
|
other identifiable groups faced specific restrictions, social hostility,
|
||||||
|
and periodically legal exclusions that affected commercial activity.
|
||||||
|
This is not modern racism but it had comparable commercial effects:
|
||||||
|
restricted access to certain markets, inability to use certain legal
|
||||||
|
instruments, exclusion from some COLLEGIA.
|
||||||
|
|
||||||
|
**Primary sources:**
|
||||||
|
- Gaius, *Institutiones* — systematic treatment of legal status categories
|
||||||
|
- Digest of Justinian, Books 1, 4, 40 — citizenship, manumission, legal capacity
|
||||||
|
- Cicero, *Pro Balbo* — citizenship as commercial prerequisite
|
||||||
|
|
||||||
|
**Secondary sources:**
|
||||||
|
- Jane Gardner, *Being a Roman Citizen* (1993)
|
||||||
|
- A.N. Sherwin-White, *The Roman Citizenship* (1973)
|
||||||
|
- John Bodel, *Epigraphic Evidence* — freedman commercial activity
|
||||||
|
|
||||||
|
### 2.2 Existing parameters affected
|
||||||
|
|
||||||
|
**`ius_accessus`**
|
||||||
|
The existing registry entry describes this as an ordinal scale (low /
|
||||||
|
medium / high). This is insufficient. IVS_ACCESSVS is not a continuous
|
||||||
|
variable — it is a structured set of legal capabilities that differ
|
||||||
|
categorically between SERVUS, LATINVS, PEREGRINUS, LIBERTUS, and CIVIS.
|
||||||
|
The schema must accommodate legal status as a discrete category, not
|
||||||
|
an ordinal score. The ordinal representation is a simplification that
|
||||||
|
will produce wrong results in legal dispute scenarios.
|
||||||
|
|
||||||
|
**`auctoritas`**
|
||||||
|
The existing registry notes AVCTORITAS as partially observable and
|
||||||
|
socially constructed. The legal status layer adds a floor and ceiling
|
||||||
|
to AVCTORITAS that is structurally imposed, not just socially earned.
|
||||||
|
A LIBERTUS cannot exceed a certain AVCTORITAS threshold regardless of
|
||||||
|
commercial success, because certain social expressions of AVCTORITAS
|
||||||
|
(holding office, certain COLLEGIA membership) are legally closed to him.
|
||||||
|
A CIVIS of low commercial achievement still has a higher AVCTORITAS
|
||||||
|
floor than a successful LIBERTUS in formal legal contexts.
|
||||||
|
|
||||||
|
**`information_quality`**
|
||||||
|
Access to commercial information in Rome was heavily mediated by
|
||||||
|
social networks that were themselves status-stratified. A PEREGRINUS
|
||||||
|
in Ostia had access to information networks within his ethnic community
|
||||||
|
but reduced access to Roman citizen networks. A LIBERTUS had access
|
||||||
|
to his former owner's network (CLIENTELA) but was excluded from others.
|
||||||
|
The `information_quality` parameter must accommodate network access
|
||||||
|
constraints derived from legal and social status.
|
||||||
|
|
||||||
|
**`negotiatio`**
|
||||||
|
Negotiation capability was not purely a personal skill — it was
|
||||||
|
mediated by legal standing. A SERVUS negotiating on behalf of an
|
||||||
|
owner could achieve certain outcomes but was legally constrained in
|
||||||
|
others. A PEREGRINUS negotiating with Roman citizens was operating
|
||||||
|
under *ius gentium*, not Roman civil law, with different remedies
|
||||||
|
available if the counterparty defaulted.
|
||||||
|
|
||||||
|
### 2.3 New parameters required
|
||||||
|
|
||||||
|
**`legal_status`**
|
||||||
|
```
|
||||||
|
token: legal_status
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: canonical
|
||||||
|
```
|
||||||
|
The actor's formal Roman legal status. Discrete categories, not ordinal:
|
||||||
|
`civis_romanus`, `latinvs`, `peregrinus`, `libertus`, `liberta`, `servus`.
|
||||||
|
This is the foundational parameter that determines the structure of
|
||||||
|
`ius_accessus` for each actor. It does not drift — it changes through
|
||||||
|
specific legal events (manumission, citizenship grant) which are
|
||||||
|
recorded as events in the time-series.
|
||||||
|
|
||||||
|
**`ethnic_community`**
|
||||||
|
```
|
||||||
|
token: ethnic_community
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: provisional
|
||||||
|
```
|
||||||
|
The actor's cultural and ethnic community affiliation, where distinct
|
||||||
|
from Roman citizen status. Affects `information_quality` within community
|
||||||
|
networks, access to community-specific commercial infrastructure (e.g.
|
||||||
|
Jewish merchant networks, Egyptian grain traders, Syrian traders in
|
||||||
|
Ostia), and exposure to community-specific legal restrictions and social
|
||||||
|
hostility. Not a racial category — a social and legal one.
|
||||||
|
|
||||||
|
**`tutor_required`**
|
||||||
|
```
|
||||||
|
token: tutor_required
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: provisional
|
||||||
|
```
|
||||||
|
Boolean. Whether the actor legally requires a male guardian (TVTOR)
|
||||||
|
to execute certain commercial transactions. Applies to women actors.
|
||||||
|
Affects `ius_accessus` for specific transaction types. A woman MERCATRIX
|
||||||
|
(female merchant — attested in inscriptions) conducting NEGOTIA without
|
||||||
|
a TVTOR faces legal exposure on certain contract types.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 3. Commercial Sex
|
||||||
|
|
||||||
|
### 3.1 Structural role
|
||||||
|
|
||||||
|
Commercial sex in Rome was a licensed, taxed, legally categorised
|
||||||
|
industry. This is not a peripheral fact — it is documented in
|
||||||
|
municipal records, legal texts, and archaeological evidence across
|
||||||
|
the Roman world including Ostia.
|
||||||
|
|
||||||
|
Key structural elements relevant to the simulation:
|
||||||
|
|
||||||
|
**MERETRIX** — a woman registered as a prostitute with the AEDILE
|
||||||
|
(municipal official). Registration was required by law (Lex Iulia
|
||||||
|
de adulteriis, 18 BCE — near our simulation period). It conferred
|
||||||
|
a specific legal status: the MERETRIX was exempt from adultery law
|
||||||
|
(applying only to respectable women) but permanently infamis —
|
||||||
|
legally disgraced, stripped of certain legal protections.
|
||||||
|
|
||||||
|
**LENO / LENA** — the brothel-keeper (male / female). A commercial
|
||||||
|
operator. Subject to the INFAMIA legal sanction, which removed certain
|
||||||
|
legal protections and rights. Taxed: the VECTIGAL MERETRICVM was a
|
||||||
|
municipal revenue source.
|
||||||
|
|
||||||
|
**FORNIX / LUPANAR** — the physical location. In Ostia, archaeologically
|
||||||
|
attested in harbour and market districts — precisely the areas the
|
||||||
|
MERCATOR operates in.
|
||||||
|
|
||||||
|
**Commercial relevance to the MERCATOR:**
|
||||||
|
- The LUPANAR was part of the harbour economy. Its proximity to docks,
|
||||||
|
warehouses, and taverns is not coincidental — it served transient
|
||||||
|
labour populations: sailors, porters, travelling merchants.
|
||||||
|
- Expenditure in this sector is a legitimate economic flow that affects
|
||||||
|
the actor's `liquiditas` and OFFICIA_BVRDEN profile.
|
||||||
|
- The LENO as commercial actor had specific legal constraints that
|
||||||
|
affected contract enforceability.
|
||||||
|
- Association with this sector affected AVCTORITAS and FAMA differently
|
||||||
|
depending on the actor's status and the visibility of the association.
|
||||||
|
|
||||||
|
**Primary sources:**
|
||||||
|
- Digest of Justinian, Book 3.2 — INFAMIA, legal consequences of
|
||||||
|
MERETRICIA profession
|
||||||
|
- CIL (Corpus Inscriptionum Latinarum) — Pompeii price lists (later
|
||||||
|
than our period but structurally informative)
|
||||||
|
- Plautus comedies — commercial and social references (earlier period,
|
||||||
|
informative for social norms)
|
||||||
|
|
||||||
|
**Secondary sources:**
|
||||||
|
- Thomas McGinn, *Prostitution, Sexuality, and the Law in Ancient Rome* (1998)
|
||||||
|
- Sarah Levin-Richardson, *The Brothel of Pompeii* (2019)
|
||||||
|
- Rebecca Flemming, *Medicine and the Making of Roman Women* (2000)
|
||||||
|
|
||||||
|
### 3.2 Existing parameters affected
|
||||||
|
|
||||||
|
**`liquiditas`**
|
||||||
|
Expenditure in this sector is a recurring cost parameter for actors
|
||||||
|
whose social patterns include harbour district activity. It is
|
||||||
|
economically indistinguishable from expenditure on food, wine, or
|
||||||
|
lodging in the simulation's accounting model — it is a cost that
|
||||||
|
reduces available capital. It must not be treated as categorically
|
||||||
|
different from other consumption costs in the schema.
|
||||||
|
|
||||||
|
**`auctoritas`**
|
||||||
|
Visible association with the sector affected AVCTORITAS differently
|
||||||
|
by social class. A high-status actor (Lentulus) visible in a LUPANAR
|
||||||
|
faces AVCTORITAS and FAMA damage. A low-status actor (Felix, Varro)
|
||||||
|
faces no particular consequence — it was unremarkable for their
|
||||||
|
social level. This is a `perceived_vs_true` interaction: the social
|
||||||
|
cost is mediated by who observes, not by the act itself.
|
||||||
|
|
||||||
|
**`fama`**
|
||||||
|
The FAMA parameter must accommodate sector-specific social visibility.
|
||||||
|
Certain locations and associations produce FAMA effects only if observed
|
||||||
|
by status-relevant witnesses. The BALNEA rumour network
|
||||||
|
(`rumor_velocity`) carries some of this information; the schema must
|
||||||
|
model that rumour content has differential impact by observer status.
|
||||||
|
|
||||||
|
**`officia_burden`**
|
||||||
|
Not applicable for the MERCATOR as consumer. Applicable if modelling
|
||||||
|
the LENO as a commercial actor type — ownership of a LUPANAR creates
|
||||||
|
specific legal and operational obligations.
|
||||||
|
|
||||||
|
### 3.3 New parameters required
|
||||||
|
|
||||||
|
**`infamia_flag`**
|
||||||
|
```
|
||||||
|
token: infamia_flag
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: canonical
|
||||||
|
```
|
||||||
|
Boolean. Whether the actor carries the legal status of INFAMIA —
|
||||||
|
legal disgrace that removes certain protections and rights. Applies
|
||||||
|
to: LENO, LENA, MERETRIX, gladiators, actors, and others defined by
|
||||||
|
Roman law. Affects `ius_accessus` (certain legal actions barred),
|
||||||
|
`auctoritas` (formal ceiling reduced), and `clientela` (certain
|
||||||
|
patron-client relationships unavailable). Not the same as low FAMA —
|
||||||
|
INFAMIA is a legal status, FAMA is a social perception.
|
||||||
|
|
||||||
|
**`sector_visibility`**
|
||||||
|
```
|
||||||
|
token: sector_visibility
|
||||||
|
scope: relation
|
||||||
|
layer: roman
|
||||||
|
maturity: provisional
|
||||||
|
```
|
||||||
|
The probability that an actor's commercial or social activity in a
|
||||||
|
specific sector is observed by status-relevant witnesses and enters
|
||||||
|
the rumour network. Modulates `fama` effects for activities that have
|
||||||
|
differential social consequences by observer. High `sector_visibility`
|
||||||
|
in the harbour district late at night produces different FAMA effects
|
||||||
|
than the same activity unseen.

## 4. Public Violence and the Arena
|
||||||
|
|
||||||
|
### 4.1 Structural role
|
||||||
|
|
||||||
|
Public violence in Rome was not an anomaly or a failure of civilization.
|
||||||
|
It was a deliberately maintained social institution with specific
|
||||||
|
economic, political, and social functions. The relevant forms for the
|
||||||
|
MERCATOR's world:
|
||||||
|
|
||||||
|
**LVDI** — public games, including gladiatorial combat (MVNERA),
|
||||||
|
animal hunts (VENATIONES), and chariot racing (LUDI CIRCENSES).
|
||||||
|
Sponsored by magistrates, wealthy patrons, and the Emperor. The sponsor
|
||||||
|
(EDITOR MVNERUM) gained AVCTORITAS and CLIENTELA in proportion to the
|
||||||
|
scale and quality of the event. This was not entertainment in the modern
|
||||||
|
sense — it was a mechanism for redistributing social capital from
|
||||||
|
wealthy to popular, cementing political alliances, and demonstrating
|
||||||
|
the sponsor's power and generosity.
|
||||||
|
|
||||||
|
**Gladiatorial schools (LVDI GLADIATORUM)** — commercial operations.
|
||||||
|
A LANISTA (gladiatorial trainer/manager) purchased, trained, and hired
|
||||||
|
out gladiators. This was a profitable but INFAMIA-carrying business.
|
||||||
|
Gladiators themselves were often enslaved persons or condemned criminals,
|
||||||
|
but also included free volunteers (AVCTORAMENTVM) drawn by pay, status
|
||||||
|
within the arena world, and — occasionally — the release from debt.
|
||||||
|
|
||||||
|
**Capital punishment** — public execution (SVPPLICIUM) was a regular
|
||||||
|
civic event. Criminals, slaves, and enemies of the state were executed
|
||||||
|
publicly in ways that served as both deterrent and spectacle. This is
|
||||||
|
not tangential to the commercial world — condemned criminals included
|
||||||
|
defaulted debtors in some circumstances.
|
||||||
|
|
||||||
|
**Commercial relevance to the MERCATOR:**
|
||||||
|
- Attending, sponsoring, or being seen at LVDI was an AVCTORITAS and
|
||||||
|
CLIENTELA event, not merely entertainment.
|
||||||
|
- The LANISTA as commercial actor operated within specific legal
|
||||||
|
constraints (INFAMIA) while conducting profitable trade in human
|
||||||
|
combat capacity.
|
||||||
|
- The economic demand generated by LVDI — for animals, equipment,
|
||||||
|
food, temporary labour, lodging — was a commercial opportunity the
|
||||||
|
MERCATOR could service.
|
||||||
|
- The EDITOR MVNERUM role was a form of `liquiditas` expenditure that
|
||||||
|
produced `auctoritas` returns — one of the clearest Roman examples
|
||||||
|
of converting money into social capital.
|
||||||
|
|
||||||
|
**Primary sources:**
|
||||||
|

|
||||||
|
scale of games

||||||

|
||||||

||||||

|

|
||||||
|
|
||||||
|
### 4.2 Existing parameters affected
|
||||||
|
|
||||||
|
**`auctoritas`**
|
||||||
|
The EDITOR MVNERUM mechanism is the clearest Roman example of direct
|
||||||
|
`liquiditas` → `auctoritas` conversion. The existing registry entry
|
||||||
|
does not describe this pathway explicitly. It must be added: spending
|
||||||
|
on public sponsorship (LVDI, public feasts, building dedications) is
|
||||||
|
a direct investment in AVCTORITAS that bypasses the slow accumulation
|
||||||
|
through repeated commercial reliability. It is also irreversible —
|
||||||
|
a patron who sponsors games cannot unsponsor them, and the AVCTORITAS
|
||||||
|
gained decays if not maintained by further sponsorship.
|
||||||
|
|
||||||
|
**`clientela`**
|
||||||
|
Public games generated CLIENTELA directly. Attendees who received
|
||||||
|
free admission or gifts (MISSILIA — tokens thrown to the crowd)
|
||||||
|
entered a diffuse client relationship with the sponsor. This is a
|
||||||
|
mass CLIENTELA acquisition mechanism — distinct from the individual
|
||||||
|
cultivation described in the existing registry entry. The schema must
|
||||||
|
accommodate both forms.
|
||||||
|
|
||||||
|
**`officia_burden`**
|
||||||
|
The EDITOR MVNERUM role created specific obligations: to the audience
|
||||||
|
(expectation of future games), to the performers contracted, to the
|
||||||
|
animals suppliers, to the venue. Once entered, the role generated
|
||||||
|
ongoing OFFICIA_BVRDEN whether or not the actor wished to continue.
|
||||||
|
|
||||||
|
**`liquiditas`**
|
||||||
|
Sponsoring LVDI was a major capital expenditure. The scale ranged from
|
||||||
|
modest municipal games to the multi-day spectacles of the Imperial
|
||||||
|
period. For a working MERCATOR, even modest sponsorship represented
|
||||||
|
a significant `liquiditas` commitment with an uncertain `auctoritas`
|
||||||
|
return — because the social capital gained depended on attendance,
|
||||||
|
weather, the quality of the performance, and the political climate.
|
||||||
|
|
||||||
|
### 4.3 New parameters required
|
||||||
|
|
||||||
|
**`sponsorship_investment`**
|
||||||
|
```
|
||||||
|
token: sponsorship_investment
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: provisional
|
||||||
|
```
|
||||||
|
Capital committed by an actor to public sponsorship (LVDI, public
|
||||||
|
feasts, building dedications). Produces `auctoritas` return at a
|
||||||
|
rate modulated by event scale, attendance, and political climate.
|
||||||
|
The return is delayed (AVCTORITAS accrues after the event, not during
|
||||||
|
the expenditure) and uncertain (bad weather, poor performance, or
|
||||||
|
political interference reduces return). Irreversible once committed.
|
||||||
|
|
||||||
|
**`arena_demand_index`**
|
||||||
|
```
|
||||||
|
token: arena_demand_index
|
||||||
|
scope: city
|
||||||
|
layer: roman
|
||||||
|
maturity: provisional
|
||||||
|
```
|
||||||
|
The current commercial demand generated by scheduled or recent LVDI
|
||||||
|
in a city — for animals, equipment, food, lodging, and temporary
|
||||||
|
labour. A city in the week before major games has different commercial
|
||||||
|
conditions from a city in a quiet period. Affects `food_price_index`,
|
||||||
|
`porter_availability`, `storage_fee_index`, and `dock_congestion`.
|
||||||
|
|
||||||
|
**`lanista_flag`**
|
||||||
|
```
|
||||||
|
token: lanista_flag
|
||||||
|
scope: actor
|
||||||
|
layer: roman
|
||||||
|
maturity: provisional
|
||||||
|
```
|
||||||
|
Boolean. Whether the actor is operating as or in partnership with a
|
||||||
|
LANISTA (gladiatorial school operator). Applies INFAMIA consequences
|
||||||
|
(see `infamia_flag`) while enabling access to specific commercial
|
||||||
|
networks (arena supply chains, condemned labour pools). A commercial
|
||||||
|
actor who avoids this sector loses certain opportunities; one who
|
||||||
|
enters it gains opportunities at AVCTORITAS cost.

|
|---|---|
|

|
| `ius_accessus` | Must become a structured legal capability set, not an ordinal scale. Keyed to `legal_status`. |
|
||||||

|
||||||
|
| `officia_burden` | Must include: liability for enslaved persons' commercial acts; sponsorship obligations once entered. |
|
||||||
|
| `information_quality` | Must accommodate: network access constraints derived from `legal_status` and `ethnic_community`. |
|
||||||
|
| `fama` | Must accommodate: `sector_visibility` modulation — FAMA effects are observer-dependent, not universal. |
|

## 6. Schema Discipline
|
||||||
|
|
||||||
|
These parameters must not be encoded differently from any other parameter
|
||||||
|
in the schema. They are historical facts about a specific period and
|
||||||
|
place, not editorial content. The same precision, confidence tagging,
|
||||||
|
and source citation standards apply here as to cargo weights and customs
|
||||||
|
duties.
|
||||||
|
|
||||||
|
Uncertainty is a first-class record. Where source data is thin —
|
||||||
|
particularly for labour cost rates and PECULIUM values specific to
|
||||||
|
Ostia in 14 BCE — the parameter is marked `maturity: research_needed`
|
||||||
|
and the confidence tag reflects the gap. A gap honestly documented is
|
||||||
|
more useful than a false precision.
