Athenaeum
(
Ἀθήναιον). The first public educational institution at
Rome, built by Hadrian about A.D. 135. The building was in the form of a theatre, and
brilliantly fitted up. There rhetoricians and poets held their recitations, and salaried
professors gave their lectures in the various branches of general liberal
education—philosophy and rhetoric, as well as grammar and jurisprudence. This
continued until at least the fifth century a. d.
