 The distributary of the Mekong revealed in the aerial photography was probably the "Saenus" mentioned in Ptolemy’s "Geography" as the western branch of the Mekong, which Ptolemy called the "Cottiaris".The Cattigara in Ptolemy's Geography could be derived from a Sanskrit word, either "Kottinagara" (Strong City) or "Kirtinagara" (Renowned City).The remains found at Óc Eo include pottery, tools, jewelry, casts for making jewelry, coins, and religious statues.
