Ptolemy son of Abubus

Ptolemy son of Abubus was an official in the early Hasmonean kingdom which then controlled Judea. According to the book of 1 Maccabees, in 135 BC, he served as the governor of Jericho. While High Priest Simon Thassi was visiting, Ptolemy orchestrated the murder of Simon and two of his sons, as well as some of Simon's servants. This act of betrayal of guest right earned Ptolemy a place in Dante's The Divine Comedy; one of the sections of the ninth layer of hell described in Inferno is called Ptolomea, where those who betray guests in their home suffer.

In culture
Ptolemy is perhaps most famous for a reference to him in Dante Alighieri's The Divine Comedy. In Inferno, the ninth and deepest layer of hell is for the sin of treachery, which Dante saw as the gravest of all crimes. Inhabitants include Satan, Judas Iscariot, and Cain. The ninth layer is further subdivided into four sections by the type of treachery: Caina, Antenora, Ptolomea, and Judecca. In Canto 33, Fra Alberigo is tortured in the third section, Ptolomea (Italian: Tolomea), a place in hell designated for traitors against guests in their home. While Ptolemy is not directly mentioned, he is presumably punished in the section named after him (similar to how Cain resides in Caina and Judas in Judecca) for his betrayal of Simon and his entourage while they were his guests.
