Reading History and Poetry

legendi etiam poetae, cognoscendae historiae, omnium bonarum artium doctores atque scriptores eligendi et pervolutandi et exercitationis causa laudandi, interpretandi, corrigendi, vituperandi, refellendi
 
also we must also read poetry, master history, and select instructors and writers from all the noble arts to mull over thoroughly and, for the sake of practice, we must praise, explain, correct, criticise and refute them.

Cicero, De oratore, I.34,158. My translation.
