"On the banks of the Nile, Trachinus, the captain of the pirates, prepares a feast to solemnize his nuptials with Chariclea; but Calasiris, with considerable ingenuity having persuaded Pelorus, the second in command, that Chariclea is enamoured of him, a contest naturally arises between him and Trachinus during the feast, and the other pirates, espousing different sides of the quarrel, are all slain except Pelorus, who is attacked and put to flight by Theagenes. The stratagem of Calasiris, however, is of little avail, except to himself: for immediately after the contest, while Calasiris is sitting on a hill at some distance, Theagenes and Chariclea are seized by a band of Egyptian robbers, who conduct them to an establishment formed on an island in a remote lake. Thyamis, the captain of the banditti, becomes enamoured of Chariclea, and declares an intention of espousing her. Chariclea pretends that she is the sister of Theagenes, in order that the jealousy of the robber may not be excited, and the safety of her lover endangered. Chariclea, however, is not long compelled to assume this character of sister. "The colony is speedily destroyed by the forces of the satrap of Egypt, who was excited to this act of authority by a complaint from Nausicles, a Greek merchant, that the banditti had carried off his mistress. Thyamis, the captain of the robbers, escapes by flight, and Cnemon, a young Athenian, who had been detained in the colony, and with whom Theagenes had formed a friendship during his confinement, sets out in quest of him. "Theagenes and Chariclea depart soon after on their way to a certain village, where they had agreed to meet Cnemon, but are intercepted on the road by the satrap's forces. "Theagenes is sent as a present to the King of Persia; and Chariclea, being falsely claimed by Nausicles as his mistress, is conducted to his house. Here Calasiris had accidentally fixed his abode, since his separation from Theagenes and Chariclea; and was also doing the honours of the house to Cnemon in the landlord's absence. Chariclea being recognised by Calasiris, Nausicles abandons the claim to her which he had advanced, and sets sail with Cnemon for Greece, while Calasiris and Chariclea proceed in search of Theagenes. On arriving at Memphis, they find that with his usual good luck, he had again fallen into the power of Thyamis, and was besieging that capital along with the robber. A treaty of peace, however, is speedily concluded. Thyamis is discovered to be the son of Calasiris, and is elected high-priest of Memphis.
