The Mouseion of Alexandria (; ), which arguably included the Library of Alexandria, was an institution said to have been founded by Ptolemy I Soter and his son Ptolemy II Philadelphus. Originally, the word mouseion meant any place that was dedicated to the Muses, often related to the study of music or poetry, but later associated with sites of learning such as Plato's Academy and Aristotle's Lyceum.
