Who were Virgil's major influences?

It would seem that Virgil, a Classical Roman poet, started
his education at the age of five. His father was a wealthy landowner, so paying for
Virgil's education was by no means difficult.  At first it seemed Virgil would pursue
studies in rhetoric and the law.  However, he soon turned his attention to
poetry.

Virgil is remembered for writing three major works.
 They are the Eclogues (or Bucolics), the
Georgics, and the Aeneid, along with several
other minor poems. (Virgil's published works greatly influenced Latin
poetry.)

His Aeneid is considered a
national Roman epic, and this piece seems to have been influenced by Homer's
The Iliad.  However, it seems Virgil was also influenced the the
neoteric writers Pollio and Cinna.
