# A temple of Divus Traianus is completed in Trajan’s Forum under Hadrian

Date: 126

## The fact

[Hadrian](/people/hadrian) completed a temple of Divus Traianus in the Forum of Trajan. The dated cult building is not [Trajan](/people/trajan)’s 113 forum dedication and not the Pantheon. Hadrian’s documented role is: He completed or dedicated a temple to the deified Trajan (and Plotina) in the Forum of Trajan. The cult is shared with the Senate’s deification; the building is Hadrianic completion. Do not twin this with Trajan’s own Forum dedication of 113. A successor’s cult-temple is a later instrument. Later editors, printers, and excavators remain named where they appear. Hadrian's documented role is: He completed or dedicated a temple to the deified Trajan (and Plotina) in the Forum of Trajan. The cult is shared with the Senate’s deification; the building is Hadrianic completion.

The public setting is the file around 0126-06-01. Unnamed clerks, soldiers, printers, or later editors may appear without becoming this instrument. The instrument stays A temple of Divus Traianus is completed in Trajan’s Forum under Hadrian.
