Adrianis (also Hadrianis, Ancient Greek: Ἀδριανίς) was a tribe (phyle) added by the ancient Athenians to the previous list of 12 tribes in 126−127 A.D.[1] The tribe was named after the Roman emperor Hadrian.
Hadrian first visited Athens in the fall of 125[verification needed] A.D., with the Athenians considering him as their savior.
The emperor liked the city and stayed until spring, with his largesse helping to build some of the most interesting buildings of Athens,[2] including the Temple of Olympian Zeus.
[3] Hadrian's statue was added to the Monument of the Eponymous Heroes, starting the so-called Period V. While Athenians added the new tribe to their list at seventh place,[4] modern researchers use the Roman numeral XV to designate Adrianis.
The 13 demes that formed Adrianis were collected from all 12 old phylai ("rule-of-one"), with the 13th, Antinoeis, newly created and named after Antinous, Hadrian's favorite.
