Mysius

{{For|the French director with the surname|Léa Mysius}}

In Greek mythology, Mysius (Ancient Greek: Μύσιος) was a figure meant to provide an etiology for Mysia as a surname of Demeter. He was said to have received Demeter hospitably in his home in Argos as she was searching for Persephone, and to have founded a sanctuary of Demeter Mysia, known as "Mysaeum", located at the distance of about sixty stadia from Pellene; another temple of Demeter Mysia was reportedly situated on the road from Mycenae to Argos.Pausanias, Description of Greece, 2. 18. 3; 2. 35. 4; 7. 27. 9

Mysius is portrayed on a relief uncovered in Lerna alongside Demeter and Chrysanthis: the latter was presumably seen as his daughter or wife.Realencyclopädie der Classischen Altertumswissenschaft, Band III, Halbband 6, Campanus ager-Claudius (1899), s. 2483; Band XVI, Halbband 31, Molatzes-Myssi (1933), s. 1188
