I have been informed this is the private bathhouse of Ardaburio. In the Wikipedia I found there is a historical man of that name, i.e.: "Ardabur (died 471) was the son of Flavius Ardabur Aspar,[1] Master of Horse and Magister Militum of the Eastern Roman Empire in the fifth century. Ardabur apparently often served under his famous father during his campaigns. In 466 Ardabur was accused of a treasonous plot, probably by his father's political enemies. The accusation accelerated Aspar's fall from power. Both Ardabur and Aspar were killed in a riot in 471." I am not certain they are the same.

I thank the viewer for the comment.
