 Cattigara was the name given by the 2nd-century Alexandrian geographer Claudius Ptolemy to the land on the easternmost shore of the Indian Sea at (due to a scribal error) 8½° south of the Equator.The name "Cattigara" was probably derived from the Sanskrit "Kirti-nagara" कीर्ति- नगर "Renowned City" or "Kotti-nagara" कोटि-नगर "Strong City".Scholarship has now determined that Ptolemy's Cattigara was at 8½° north of the Equator and was the forerunner of Saigon as the main port and entrepot at the mouth of the Mekong.
