Bartholomew of Neocastro (c. 1240 – after 1293) was an Italian jurist, and author of a chronicle called the Historia Sicula, which covers the years from 1250 to 1293.[1][2]
Few things are known about Bartholomew. It is known that he was a bureaucrat from Messina who first practiced law before assuming bureaucratic assignments with the Aragonese court of the Kingdom of Sicily. These included several delicate diplomatic missions.[3] It is in this position that Bartholomew was a direct and close witness to the narrated series of events. In some cases, he was a spectator from the inside.
