The crescent moon symbol used as a form of blazon is not a feature of early Islam, as would be expected if it were linked to Pre-Islamic pagan roots. The use of the crescent symbol on Muslim flags originates during the later Middle Ages.[14] 14th-century Muslim flags with an upward-pointing crescent in a monocolor field included the flags of Gabes, Tlemcen (Tilimsi), Damas and Lucania, Cairo, Mahdia, Tunis and Buda.[15]
