A mammisi (mamisi) is an ancient Egyptian small chapel attached to a larger temple (usually in front of the pylons[1]), built from the Late Period,[2][3] and associated with the nativity of a god.[1] The word is derived from Coptic – the last phase of the ancient Egyptian language – meaning "birth place".[1][2] Its usage is attributed to the French egyptologist Jean-François Champollion (1790–1832).[3]
