Euphemia was a virgin of Chalcedon who was martyred in the early fourth century (accounts differ it was either AD 307, or AD 303). It is said, that at the council of Chalcedon (which debated . . . OK fought) over the interrelationship of the two natures in Christ, Euphemia played an important role. The two competing parties (the “orthodox” and the “monophysite”) placed a summary of their thesis in the saint’s sarcophagus. In the morning it was discovered that the orthodox document was in the saint’s hand, and the monophysite document under her feet.
One has to wonder though – did they post a guard at the shrine over night?
Today is the 14th Wednesday after Petntecost, and the third day of the Feast of the Exaltation of the Cross.
