We know very little of both Sasints, with most accounts coming from two sources - a manuscript from Ancona and a second preserved by the Biblioteca Vallicelliana in Rome. Both sources list Saint Palatias as a noblewoman living in the town of Ancona, Italy. Her slave or wetnurse Laurentia converted her to Christianity during the Diocletian persecutions.
The two were arrested and martyred by the Emperor Diocletian. In Italian, the names are Sante Palazia e Laurenzia and both names appear in liturgical texts and statues of her appear from the the 11th century on wards. Their relics were collected in a single bronze urn that was donated to Ancona Cathedral by Pope Benedict XIV.
