Small vessels may coal at Naos, an island in the Gulf of Panama, which is owned by the United States.
On the walls of the temple is engraved the famous Monumentum Ancyranum, a long inscription in Latin and Greek describing the Res gestae divi Augusti; the Latin portion being inscribed on the inner left-hand wall of the pronaos, the Greek on the outside wall of the naos (cella).
Towards the eastern end of this terrace are the scanty remains of a building which can hardly be anything but the temple of Zeus; it appears to have consisted of pronaos, naos or cella, and opisthodomus, and some of the lower drums of the internal columns of the cella were still resting on their foundations.
In 1825 another volcanic eruption took place accompanied by earthquakes, and two hills were thrown up. The port of Naos on the south-east of the island affords safe anchorage.
