Nicene and Post-Nicene Fathers, Ser. II, Vol. VII:
Select Letters of Saint Gregory Nazianzen.: Letter XXVIII

p. 468 Ep. XXVIII.

In visiting the mountain cities which border on Pamphylia I fished up in the Mountains a sea Glaucus; I did not drag the fish out of the depths with a net of flax, but I snared my game with the love of a friend.  And having once taught my Glaucus to travel by land, I sent him as the bearer of a letter to Your Goodness.  Please receive him kindly, and honour him with the hospitality commended in the Bible, not forgetting the vegetables.
