This original Musaeum (“Institution of the Muses”) was the home of music or poetry, a philosophical school and library such as Plato’s Academy, also a storehouse of texts. […]
More than 1,000 scholars lived in the Mouseion at a given time. Staff members and scholars were salaried by the Mouseion and paid no taxes. They also received free meals, free room and board, and free servants. The Mouseion was administered by a priest appointed by the Pharaoh.
