Etymology

The English word museum comes from Latin, and is pluralized as museums (or rarely, musea). It is originally from the Ancient Greek Μουσεῖον (mouseion), which denotes a place or temple dedicated to the muses (the patron divinities in Greek mythology of the arts), and hence was a building set apart for study and the arts, especially the Musaeum (institute) for philosophy and research at Alexandria, built under Ptolemy I Soter about 280 BC.
