desudare in scholae umbra or umbraculis

Etymology:

• Cf. umbra, umbracula (-orum), and umbratilis (vid. vii. 2, vita umbratilis), used of the retired life of a savant as opposed to sol, lux forior 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. Transcriber's Note: the original text indeed has sol, lux ori. But that is wrong as can be seen from the French edition using sol, lux fori.
