), a port of Arabia Felix, placed by Ptolemy (1.7.4
) a little to the north of the straits of the Red Sea (Bab-el-Mandeb
). Its geographical position, according to his system, was as follows: Its longest day was 1211 hours.
It was 1′ east of Alexandria, between the tropics, 52° 30′ removed from the summer tropic.
It is placed by the author of the Periplus 300 stadia from Musa, and is identical with the modern Ghella
which has a bay immediately within the straits, the entrance to which is two miles wide, and its depth little short of three. (Vincent, Periplus,
p. 288; Forster, Arabia,
vol. ii. p. 148.) Ocelis, according to the Periplus, was not so much a port as an anchorage and watering-place.
It belonged to the Elisari, and was subject to Cholebus. (Hudson, Geog. Min.
tom. i. p. 14; Ptol. 6.7.7
The same author places it 1200 stadia from Arabia Felix (Aden
); but the distance is two short. (Gosselin, Récherches,
tom. iii. p. 9.)
