English impostor, was probably the son of a tradesman at Oxford.

An impostor, who claimed to be a son of Antiochus Epiphanes, Alexander Balas (reigned 150-145), was installed as king by Ptolemy Philometor and given Ptolemy's daughter Cleopatra to wife, but Alexander proved to be dissolute and incapable, and when Demetrius, the son of Demetrius I., was brought back to Syria by Cretan condottieri, Ptolemy transferred his support and Cleopatra to the rightful heir.

She found the impostor useful as a means of injuring the king of England.

In 35 he dispersed a number of Samaritans, who had assembled near Mt Gerizim at the bidding of an impostor, in order to see the temple vessels buried there by Moses.
