Posthumianus, of Aquitania
Posthumianus (2), a friend of Sulpicius Severus of Gaul and Paulinus
of Nola, was a native of Aquitania, and made at least two journeys to the East.
After the first, when he made the acquaintance of Jerome at Bethlehem, he appears
to have visited Campania to see Paulinus (S. Paulini, Epp. 16 in Migne.
Patr. Lat. lxi. 227). He sailed from Narbonne in 401 or 402 on his second
voyage, of which a full and interesting account is in bk. i. of the Dialogues
of Sulpicius Severus (Patr. Lat. xx. 183), in which Posthumianus with
Severus and Gallus are the speakers. In five days he reached Carthage, where
he visited the tomb of St. Cyprian. Detained between Africa and Cyrene by bad
weather, he landed to explore the country, which was inhabited by a very primitive
tribe, who, however, were Christians, and was hospitably entertained by a priest.
Alexandria was then convulsed by the quarrel between the patriarch Theophilus
and the monks about the writings of Origen, and Posthumianus went on by land
to Bethlehem, where he spent six months with Jerome, whom he praises highly
both for virtue and learning. Posthumianus then returned to Alexandria, and
thence went to the Thebaid, spending a year and seven months visiting its monasteries
and hermitages. He penetrated into the Sinaitic peninsula, saw the Red Sea,
and ascended Mount Sinai. After three years' absence he returned, taking 30
days from Alexandria to Marseilles. He may have been the priest of that name
who was present at the death of Paulinus (Uranius, Ep. in Patr. Lat.
