“Each day in the week, the planet to which the day was sacred was invoked in a fixed spot in the crypt; and Sunday, over which the Sun presided, was especially holy . .
“The rites which they [the Mithraists] practised ofered numerous analogies . . They also held Sunday sa- cred, and celebrated the birth of the Sun [god] on the 25th of December.”—Franz Cumont, the Mysteries of Mithra, Trans. by T.J. McCormack, 167, 191.
