some of the Greeks [heathen] converted to Christianity, who understood the hieroglyphics, interpreted this cross-like figure to signify ‘The Life to come.’ The Christians, seizing on this as in favour of their religion, gathered boldness and assurance; and as it was shown by other sacred characters that the temple of Serapis was to have an end when was brought to light this cruciform character, signifying ‘The Life to come,’ a great number were converted and were baptized, confessing their sins[1].”
Rufinus, who tells the story also, says that this took place at the destruction of the Serapium at Canopus[2]; but Socrates and Sozomen probably followed Sophronius, who wrote a book on the destruction of the Serapium, and locate the event in Alexandria[3].
Rufinus says, “The Egyptians are said to have the sign of the Lord’s cross among those letters which are called sacerdotal—of which letter or figure this, they say, is the interpretation: ‘The Life to come.’”
