# Tetrarchic ceremonial (proskynesis, Jovian/Herculian titles) sacralises living rulers

Date: 293

## The fact

From the 290s [Diocletian](/people/diocletian)’s court used Jovius/Herculius titles, jewelled costume, and adoratio as received, a dominate ceremonial that made the living emperor a sacral object.

It is one event.

## Context

There was no democracy to erode. The analogical path is against remaining civic theatre of a princeps among senators. Medium confidence on unique welfare sign.

Diocletian’s documented role is bounded by other offices and collaborators named in the sources below. Sharing a field with them is not a reason to drop a documented act, and it is not a reason to assign later consequences done in the name after death.

Dominate as later label. Court ceremonial from the 290s. Analogical: against any remaining principate theatre of a first citizen.
Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers date the row.

## Evidence and sources

Cambridge and Britannica independently describe dominate ceremonial; Lactantius moralizes it as pride.

Official or archival record: Cambridge Ancient History (https://www.cambridge.org/core/books/cambridge-ancient-history/; Cambridge University Press).

## Significance

Sacralising living rulers is a civic-resilience harm of medium confidence.

Jewels are not the 303 edict. Keep killing distinct from costume.

Sacralising living rulers is a civic-resilience harm of medium confidence.

## What is established and what is not

Established: received ceremonial of adoratio and divine nicknames. Not established: that every subject performed it daily.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.

Established here: a sourced, dated public instrument with a named contribution by Diocletian.

What would change the picture: a contradictory original with a different date, signatory, or non-occurrence; a demonstrated forgery; or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of other causes.

They are not a public rating.
