Bust of VespasianJosephus tells us that, after the fall of Masada (The Jewish War 7, 420-36), some fighters, having escaped from the disaster and taken refuge in Egypt, had attempted to foment a revolutionary movement within the ranks of the Jews of Egypt. The prefect of Egypt, Tiberius Julius Lupus, brought news of this to the ears of Emperor Vespasian, who ordered the demolition of the Jewish temple in Leontopolis: in Roman eyes, that vestige of the bygone glory of the Oniads was a dangerous symbol of the independence of the Jewish people. Lupus and his successor, Valerius Paulinus, contented themselves with stopping the services and closing the sanctuary. Lupus was in charge from 71 until 73 C.E.; Paulinus succeeded him at the end of 73 or the beginning of 74. At that time the sanctuary was shut down permanently.
