The Byzantine scholar John Lydus (6th century) explains the festival as commemorating the "mud" from the flooding of the Nile, which generates fertility and ends hunger and drought, and was probably thought to be embodied by the birth of Harpocrates, who in art is depicted emerging from mud and bearing a cornucopia.[7]
Participants in the Pelusia were sprinkled with water in order to obtain rebirth (regeneratio) and immunity from offenses to the gods (impunitas periurorum). The sprinkling is thought to mimic the symbolic effect of the flooding, and water from the Nile itself may have been used as a form of "holy water" as it was in other ceremonies of Isis brought to Rome. In Christian discourse of the time, regeneratio was used in connection with baptism. The Christian polemicistTertullian (d. ca. 225) contrasts the rites of Pelusia with what he sees as the superior efficacy of baptism.[8]
In Egypt, the Pelusia of March 20 marked the beginning of the sailing season. The day was under the protection of Isis and Serapis.[9]
