September 1137 CE
The younger Ptolemy had entered the political scene of central Italy for the first time in 1117, when he appeared as joint count of Tusculum with his father Ptolemy I and is given in marriage to Bertha, illegitimate daughter of Henry V, Holy Roman Emperor.
At this time, the counts of Tusculum had first claimed descent through the gentes Julii and Octavii, a claim Ptolemy has continued.
The counts are also confirmed in their possession of all the territory of the Consul Gregory, Ptolemy I's grandfather.
When the Emperor Lothair II marches home from Southern Italy in 1137, Ptolemy II meets him at Tivoli.
Here, Lothair confirms all of Ptolemy's possessions and his title of "Prince of Latium."
In turn, Ptolemy gives his son Raino over to the emperor as a pledge of loyalty.
