H. W. (Henry William) Auden translation
Cf. umbra, umbracula (-orum), and umbratilis (vid. vii. 2, vita umbratilis), used of the retired life of a savant as opposed to sol, lux fori[TR1] or forensis. Cf. De Legg. 3. 6. 14 Phalereus ille Demetrius mirabiliter doctrinam ex umbraculis eruditorum otioque non modo in solem atque in pulverem sed in ipsum discrimen aciemque produxit.
