There is no corroboration of a sojourn of Basil of Cæsarea at Antioch.  Libanius was at Constantinople in 347, He does not seem to have been at Antioch until 353, D.C.B. iii. 710, when Basil was at Athens. and there Basil may have attended his lectures. cf. the correspondence with Libanius, of which the genuineness has been questioned, in Letters cccxxxv.–ccclix.  Letter cccxxxix. suggests a possibility of some study of Hebrew.  But Basil always uses the LXX.
