 Other examples include Motya in Sicily from the 6th century BC, which performed an uncertain purpose, (measuring 35 metres x 51 metres), although it has been suggested this cothon might even have been closable and drainable to form a dry dock, Mahdia in Tunisia from the 7th century BC, (which measured 72 metres x 56 metres) and one from Kition in Cyprus.In ancient times "cothon" was only used to describe the harbor at Carthage.In modern times, however, archaeologists use the term to refer to similar ancient harbors constructed of a man-made basin connected to the sea by a channel.
