Praxedes (Πραξιδίκη) is from the Greek praxis (action) — "active doer." Saint Praxedes (2nd c.) was the Roman virgin saint, daughter of Senator Pudens, who hid Christians and collected the blood of martyrs. The Basilica di Santa Prassede in Rome contains some of the city's finest Byzantine mosaics.
Featured in Browning's poem The Bishop Orders His Tomb at Saint Praxed's Church.
Praxedes reduces to four — the number of Roman virgin saint.
