Quintus Lucilius Balbus

Quintus Lucilius Balbus (fl. 100 BC) was a Stoic philosopher from Cadiz, Spain; and a pupil of Panaetius.

He appeared to Cicero as comparable to the best Greek philosophers. He is introduced by Cicero in his dialogue On the Nature of the Gods as the expositor of the opinions of the Stoics on that subject, and his arguments are represented as of considerable weight. He was also the exponent of the Stoic opinions in Cicero's lost dialogue Hortensius.
