Aulus Gellius (ca. 125 – after 180 AD) was a Latin author and grammarian, who was probably born and certainly brought up in Rome. He was educated in Athens, after which he returned to Rome, where he held a judicial office. He is famous for his Attic Nights, a commonplace book, or compilation of notes on grammar, philosophy, history, antiquarianism and other subjects, preserving fragments of many authors and works who otherwise might be unknown today.
