One of the Kings of Ankh (back when Ankh-Morpork was known as the Kingdom of Ankh). He was king around 1 UC/1282 AM, when Unseen University was founded. This makes him the oldest-known king of Ankh-Morpork... far older then any other dated King of Ankh, much less any King of Ankh-Morpork. He was described by Albert as being a little fat man with a squeaky voice. Nothing else is known about Artorollo other then that shortly after his death, Albert attempted to reverse-engineer the Rite of AshkEnte, and was thrown to Death's Domain as a result.
