Epistulae ad Quintum fratrem

Epistulae ad Quintum fratrem (English: Letters to brother Quintus) is a collection of letters from Roman politician and orator Marcus Tullius Cicero to his younger brother, by around two years, Quintus.

[1] Like Marcus Cicero's Epistulae ad familiares (Letters to friends), these letters were likely published after both Cicerones' deaths by Marcus Tullius Tiro.

Letters to brother Quintus start with an advisory letter, possibly circulated publicly, advising Quintus on how to administer a province.

It was sent around the start of 59 BC; at this time Quintus was proconsular governor of Asia.

[3] Quintus held various posts during these later letters: he was in Sardinia serving as one of Pompey's lieutenants in 54 before joining Caesar in Gaul.
