Horace's father was probably a Venutian taken captive by Romans in the Social War, or possibly he was descended from a Sabine captured in the Samnite Wars. Either way, he was a slave for at least part of his life. He was evidently a man of strong abilities however and managed to gain his freedom and improve his social position. Thus Horace claimed to be the free-born son of a prosperous 'coactor'. The term 'coactor' could denote various roles, such as tax collector, but its use by Horace was explained by scholia as a reference to 'coactor argentareus' i.e. an auctioneer with some of the functions of a banker, paying the seller out of his own funds and later recovering the sum with interest from the buyer.
