# At Constantinople Theodosius lays out the Forum Tauri programme as a civic square on a Trajanic model

Date: 386

## The fact

Britannica records the Forum Tauri as the outstanding Constantinopolitan measure of these years, modelled on [Trajan](/people/trajan)’s Forum. DIR independently treats the capital residence.

It is one event.

## Context

A new public square is a cohesion-and-capital path. Spolia and fiscal extraction are mixed and not stored as a second forum row here. Shared architects remain unnamed.

[Theodosius I](/people/theodosius-i)’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.

Britannica attributes the Forum Tauri plan to the years he stayed mainly in [Constantinople](/people/bartholomew-i-of-constantinople) from late 380. Later column and ruins are evidence, not 386 type. He did not file a UNESCO form.

Named person as heading of the dated public instrument. Later editors, museums, printers, or offices share publication. Complex where later carriers are the surviving public file.

## Evidence and sources

Britannica — Theodosius I and De Imperatoribus Romanis — Theodosius I independently describe this instrument.

Official or archival record: Britannica — Theodosius I (https://www.britannica.com/biography/Theodosius-I; Encyclopaedia Britannica).

## Significance

Forum Tauri is a cohesion path of high confidence on the programme in standard lives, low on unique welfare coefficients.

## What is established and what is not

Established as a sourced public record of this instrument at the date assigned here.

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 Theodosius I.

They are not a public rating.

The driver `social-cohesion` is attached because the mechanism named in Significance follows from this instrument, not because a standing list of welfare headings needed another tick. Theodosius I did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A portrait or conventional bust is not this mechanism. Allegation, reconstruction, and established occurrence stay distinct. Do not treat later ruins as 386 autograph masonry. Do not store a museum ticket as his act. Keep the carrier date of later English distinct from the received historical year stored in the date field. Do not read a later English edition as a recovered autograph of Theodosius I.
