Established in 1981 by Irish writers and supported by the Arts Council of Ireland, it is one of Ireland's most eminent art organizations. The name derives from the Gaelic word, "aos dana", meaning people of the arts. Membership, limited to 250 living artists and set by the Arts Council, is composed of living Irish artists who have each produced original and creative work---painting, drawing, sculpture, literature and music.
