Agisymba (Ancient Greek: Ἀγίσυμβα) was an unidentified country located in Africa mentioned by Ptolemy in the middle of the 2nd century AD.
According to Ptolemy's writings, Agisymba was found a four months' journey south of Fezzan and was characterized by large animals, such as rhinoceroses and elephants, as well as many tall mountains.
[citation needed] Ptolemy's account is based on that written by Marinus of Tyre between 107 and 115 AD.
In AD 90 a traveller, probably a trader, called Julius Maternus, profiting from the improved relations between the Romans and the Garamantes at this time – no doubt as a result of Flaccus's success – made his way from Leptis Magna through the land of the Garamantes to the land of Agisymba, where there were rhinoceroses.
[1] Indeed, Ptolemy wrote that around 90 AD, Julius Maternus (or Matiernus) undertook a mainly commercial expedition.
