See Isaiah 11:11, Jeremiah 44:1, 44:15, Ezekiel 29:14, 30:14. The Targum on 1 Chronicles 1:12 renders this as Pentpoletai, most probably Pentapolis, an Egyptian district also called Cyrenaica, although the Targum on Genesis 10 reverses the definition of Pathrusim and Casluchim. In the Midrash it is rendered as Parvitoth (Bereshith Rabbah 37).
From the Petrusim came legends concerning the Ourea, Hecatonchires, The Gygantes, as well as Cyclopes, Pontus, Nereus, Thaumus, Phorcys, Ceto, Eurybia, Aphrodite, and even Typhon. Some of these were slain during the Gigantomachy/Ethiopic-Wars.
