How did St. Andrew die?

Tradition holds that St. Andrew died in Patras, Greece, in 60 or 62 A.D., crucified on an “X” shaped cross. He was killed in this manner because he said he was unworthy to be crucified like Our Lord. Later, sometime between 64 and 68 A.D., his brother Peter would be crucified upside down on Rome’s Vatican Hill for the same reason.
