Origin & History of “mosaic”

Mosaic work is etymologically work ‘of the muses’. The word comes ultimately from Greek mouseion, which originally meant literally ‘place of the muses’, and has also given English museum. Somehow in medieval Latin it became altered to mūsaicus or mōsaicus, and passed via early modern Italian mosaico and French mosaïque into English as mosaic. It has no etymological connection, incidentally, with Mosaic ‘of Moses’ (17th c.).
