Though Ptolemy Philadelphus was fond of show, he was not extravagant, and his income was sufficient not only to maintain a large army and navy and protect efficiently the frontier of his kingdom, but also to leave a large reserve fund in the treasury. It was said to amount to as much as a hundred millions sterling. It was no wonder, therefore, that Alexandria became filled with sumptuous buildings. The Pharos or lighthouse was finished by Sôstratos, as well as the tomb of Alexander, whose body was moved from Memphis to the golden sarcophagus which had been prepared for it. The library of the Museum was stocked with books until 400,000 rolls of papyrus were collected together, and men of science and learning from all parts of the world were attracted to it by the munificence of the king. The principal librarianship, however, changed hands on the accession of the new king. Demetrius Phalereus, the ex-tyrant of Athens, who had been the first librarian, had offended Philadelphus by advising that the crown should descend to his elder brother instead of to himself, and he had accordingly to make way for Zênodotos of Ephesus, famous as a critic of Homer. Among the books which found a place in the great library of Alexandria was doubtless the Greek translation of the Pentateuch. Philadelphus showed remarkable favour to the Jews. The Jewish captives of his soldiers were ransomed by him and given homes in various parts of Egypt. One hundred and twenty thousand slaves were thus freed, the king paying for each 120 drachmas, or 30 shekels, the price of a slave according to the Mosaic Law. It is quite possible that there may be some truth in the legend that the Greek translation of the Old Testament was made at his desire. Whether or not we believe that he sent two Greek Jews, Aristæus and Andræus, with costly gifts to Eleazar the high-priest at Jerusalem, asking him to select fit men for the purpose, he was probably not unwilling that a copy of the sacred books of his Jewish subjects, in a form intelligible to the Greeks, should be added to the library. We must not forget that it was he who employed Manetho, the priest of Sebennytos, to write in Greek the history of his country, which he compiled from the hieroglyphic monuments and hieratic papyri of the native temples. Ptolemy III., Euergetês, the eldest son of Philadelphus, succeeded his father in B.C. 246. A war with Syria broke out at the beginning of his reign, and the march of the Egyptian army as far as Seleucia, the capital of the Syrian kingdom on the Euphrates, was one uninterrupted triumph. On his return, Ptolemy laid his offerings on the altar at Jerusalem, and thanked the God of the Jews for his success. The Jewish community might well be pardoned for believing that in the conqueror of Syria they had a new proselyte to their faith.
