(ποταμοφύλαξ/potamophýlax, 'river guard'). The potamophýlakes (Ptolemaic officials) used guard boats (attested from the 2nd cent. BC on) to guard the Nile, its branches (in the Delta) and the canals of Alexandria up to Syene (Aswan). They occasionally also carried urgent letters and were put to service collecting tolls and taxes. The potamophýlakes were conscripted into service; the office of potamophýlax was a liturgy.
