Amphilochius, not yet consecrated to Iconium, had abandoned his profession as an advocate, and was living in retirement at Ozizala, a place not far from Nazianzus, the see of his uncle Gregory, devoted to the care of his aged father, whose name he bore.  Heraclidas, it appears, had also renounced the bar, and devoted himself to religious life; but did not join Amphilochius on the ground that he was living in Basil’s hospital at Cæsarea.  cf. the letters of Gregory, first cousin of Amphilochius.  On the relationship, see Bp. Lightfoot in D.C.B. i. p. 104, and pedigree in prolegomena.
