Saïs was one of the sacred cities of Egypt: its principal deities were Neith, who gave oracles there, and Isis. The mysteries of the latter were celebrated with unusual pomp on the evening of the Feast of Lamps. Herodotus (ii. 59) terms this festival the third of the great feasts in the Egyptian calendar. It was held by night; and every one intending to be present at the sacrifices was required to light a number of lamps in the open air around his house. At what season of the year the feast of burning lamps was celebrated, Herodotus knew, but deemed it wrong to tell (ii. 62); it was, however, probably at either the vernal or autumnal equinox, since it apparently had reference to one of the capital revolutions in the solar course. An inscription, in the temple of Neith, declared her to be the Mother of the Sun. It ran thus, “I am the things that have been, and that are, and that will be; no one has uncovered my skirts; the fruit which I brought forth became the Sun.” It is probable, accordingly, that the kindling of the lamps referred to Neith, as the author of light. On the same night, apparently, were performed what the Egyptians designated as the “Mysteries of Isis.” Saïs was one of the supposed places of interment of Osiris, for that is evidently the deity whom Herodotus will not name (ii. 171), when he says that there is a burial-place of _him_ at Saïs in the temple of Athene. The mysteries were symbolical representations of the sufferings of Osiris, especially his dismemberment by Typhon. They were exhibited on the lake behind the temple of Neith. Portions of the lake may be still discerned near the hamlet Sa-el-Hadjar. _Smith, Dict. of Greek and Roman Geography, Art._ Saïs. [842] The evil or destroying genius. [843] Suez.

The second Ptolemy afterwards completed the canal, and in the most convenient part constructed an artfully contrived barrier, (διάφραγμα,) which he could open when he liked for the passage of vessels, and quickly close again, the operation being easily performed.”
