Have you ever wondered why the Phoenix is a Christmon?
"During the consulship of Paulus Fabius and Lucius Vitellius, the bird called the phoenix, after a long succession of ages, appeared in Egypt and furnished the most learned men of that country and of Greece with abundant matter for the discussion of the marvellous phenomenon. It is my wish to make known all on which they agree with several things, questionable enough indeed, but not too absurd to be noticed." The Annuls, Tacitus.
(referenced by Paul Maier in Pontius Pilate)
