What is a miracle that St Sophia performed?

A:

Sophia (Greek: 'Wisdom') was formerly a goddess of Gnostic Christianity. The Catholic-Orthodox Church also adopted Sophia and her daughters, Faith, Hope and Love as saints, but they are almost certainly mythical. Legend says that Sophia lived in Italy, dying of grief after her three daughters were beheaded in Rome on the personal orders of Emperor Hadrian.

Miracles are not generally attributed to Saint Sophia, but the three daughters had miraculous, although futile, escapes from death: Faith was scourged and went unharmed when boiling pitch was poured on her, and was then beheaded; Hope and Charity, were also beheaded after emerging unscathed from a furnace.
