Anthemius Isidorus

410–436) was a politician of the Eastern Roman Empire, the maternal uncle of the Western emperor Anthemius.

Anthemius Isidorus Theofilus, governor (praeses) of Arcadia Aegypti in 434, was probably his son.

At an indefinite period between 405 and 410, he was Proconsul of Asia, as attested by inscriptions found in Hypaepa in Lydia.

Between 4 September 410 and 29 October 412 he was praefectus urbi of Constantinople; in that capacity he received some laws preserved in the Theodosian Code and the Code of Justinian, which included one ordering him to complete the Baths of Honorius and build a portico in front of the structure.

[1] He undoubtedly obtained both offices due to the influence of his father, who, as Praetorian prefect of the East, had the real power.
