Small Doric temple within a sanctuary shared by the familiar triad Serapis, Isis and Anubis, located on a high terrace by the foothill of Cynthus. Built at the beginning of the 2nd century B.C., it was repaired by the Athenians in 135 B.C. and still contains the cult statue of the goddess. Isis, known by a variety of cult names, gave people good health and fortune and protected the sailors.
