Philo Judaeus Legatio Ad Gaium 310

[310] Did not he, when he had heard a report of the peculiar characteristics of our temple, and that there is in it no image or representation made by hands, no visible likeness of Him who is invisible, no attempt at any imitation of his nature, did not he, I say, marvel at and honour it? for as he was imbued with something more than a mere smattering of philosophy, inasmuch as he had deeply feasted on it, and continued to feast on it every day, he partly retraced in his recollection all the precepts of philosophy which his mind had previously learnt, and partly also he kept his learning alive by the conversation of the literary men who were always about him; for at his banquets and entertainments, the greatest part of the time was devoted to learned conversation, in order that not only his friends’ bodies but their minds also might be nourished.
