Maecenas was a wealthy Etruscan and friend of Augustus.  He lived from 70 BC-8 AD.
Acting in a manner similar to that of Medici, he  encouraged and supported talented writers.
Vergil and Horace were two of those who benefited from his support.
Horace, son of a wealthy freedman but supporter of the wrong side of political issues, needed the financial backing.  Vergil received support after agreeing to write the dream of Augustus, an epic celebrating the emperor himself and Rome.
