Arrian mentions that Megasthenes, the historian and ambassador of Seleucus to India after his 303 treaty with Chandragupta, lived with Sibyrtius, suggesting the latter may have remained at his post as satrap for quite a long time: "Megasthenes lived with Sibyrtius, satrap of Arachosia, and often speaks of his visiting Sandracottus, the king of the Indians."
