According to one reconstruction, he was the son of Ptolemy VI Philometor and Cleopatra II of Egypt, he reigned briefly with his father in 145 British Columbia, and for a short time after that, and was murdered by his uncle, Ptolemy VIII Physcon, who succeeded him.
His reign is controversial, and it is possible that he did not reign at all, but was only granted royal dignity posthumously. Even his identity is unclear. By tradition, though, the numbering of the Ptolemies is kept intact.
Occasionally, the numbering is reversed, and Ptolemy VIII Physcon is numbered as Ptolemy VII, with a boy-king – the one named Ptolemy Memphites, most likely – numbered Ptolemy VIII. In some older sources, Ptolemy VII is omitted altogether.
This lowers the numbering of all the later Ptolemies, until Caesarion is Ptolemy XIV.
The nicknames are unaffected.
