Kerke harbor-on the borders of Arsinoite and Memphite nome- was one of the Nile harbors which had an important role in transporting the grain from Chora to Alexandria. The aim of this article is to investigate the grain transport process to Kerke in Roman Egypt by examining the documents of Kerke. These documents furnish three matters of interest which are: Kerke harbor was the destination of grain cargoes from Karanis, Philadelphia and other villages, the grain transport process was most likely done by donkey, and the cultivators had to pay some supplementary charges along with the grain tax.
