Definitions for "Harpalus"
Harpalus was an aristocrat of Macedon and boyhood friend of Alexander the Great in the 4th century BC. Being lame in a leg, and therefore exempt from military service, Harpalus did not follow Alexander in his advance within the Persian Empire but received nonetheless a post in Asia Minor. Alexander reportedly contacted him with a demand of reading material for his spare time.
