(Σέσωστρις), or, as Diodorus calls him, SESOOSIS (Σεσόωσις), was the name given by the Greeks to the great king of Egypt, who is called in Manetho and on the monuments Ramses or Ramesses. Not only do Manetho and the monuments prove that Sesostris is the same as Ramses, but it is evident from Tacitus (Tac. Ann. 2.59) that the Egyptian priests themselves identified Ramses with Sesostris in the account which they gave to Germanicus of the victories of their great monarch. Ramses is a name common to several kings of the eighteenth, nineteenth, and twentieth dynasties ; but Sesostris must be identified with Ramses, the third king of the nineteenth dynasty, the son of Seti, and the father of Menephthah, according to the restoration of the lists of Manetho by Bunsen. This king is frequently called Ramses II., or Ramses the Great, to distinguish him from Ramses, the first king of the nineteenth dynasty. It was under the kings of the eighteenth and nineteenth
Although the Egyptian priests evidently exaggerated the exploits of Ramses-Sesostris, and probably attributed to him the achievements of many successive monarchs, yet it is evident, from the numerous monuments bearing his name still extant in Egypt, that he was a great warrior, and had extended his conquests far beyond the boundaries of Egypt. His conquest of Ethiopia is attested by his numerous monuments found in that country, and memorials of him still exist throughout the whole of Egypt, from the mouth of the Nile to the south of Nubia. In the remains of his palacetemple at Thebes we see his victories and conquests represented on the walls, and we can still trace there some of the nations of Africa and Asia whom lie subdued. We have, moreover, another striking corroboration of the Asiatic conquests of this monarch, as well as of the trustworthiness of that prince of travellers, Herodotus. The latter writer relates that most of the stelae which Sesostris set up in the countries he conquered, were no longer extant in his time, but that he had himself seen those in Palestine of Syria, with the inscriptions upon them. He also adds that he had seen in Ionia two figures (τύποι) of the same king, cut in the rock; one on the road from Ephesus to Phocaea, and another on the road from Sardis to Smyrna. Now it so happens that one of the stelae which Herodotus saw in Syria has been discovered in modern times on the side of the road leading to Beirut (the ancient Berytus), near the mouth of the river Lycus; and though the hieroglyphics are much effaced, we can still decipher the name of Ramses. The monument, too, which Herodotus saw on the road from Sardis to Smyrna, has likewise been discovered near Nymphi, the ancient Nymphaeum; and although some modern critics maintain that the latter is a Scythian monument, we can hardly believe that Herodotus could have been mistaken in the point.

Areheol. vol. x. p. 12; Classical Museum, vol. i. pp. 82, 231, where a drawing is given of the monument near Nymphi.)
The name of Sesostris is not found on monuments, and it was probably a popular surname given to the great hero of the nineteenth dynasty, and borrowed from Sesostris, one of the renowned kings of the twelfth dynasty, or perhaps from Sesorthus, a king of the third dynasty. It appears from Manetho, that Ramses-Sesostris was also called Sethosis, which Bunsen maintains ought to be read Se-sothis, and that its meaning is the son of Sethos or Seti.
