Galen (de Method. Medendi, l. v. apud Cluver. l. iv. c. 3, p. 1159, 1160) describes the lofty site, pure air, and rich milk, of Mount Lactarius, whose medicinal benefits were equally known and sought in the time of Symmachus (l. vi. epist. 18) and Cassiodorus (Var. xi. 10.). Nothing is now left except the name of the town of Lettere.
