Letters 51.3

Therefore, if he is contemplating withdrawal from the world, he will not select Canopus (although Canopus does not keep any man from living simply), nor Baiae either; for both places have begun to be resorts of vice. At Canopus luxury pampers itself to the utmost degree; at Baiae it is even more lax, as if the place itself demanded a certain amount of licence.
