Ansichten griechischer Rituale: Geburtstags-Symposium für Walter Burkert

Even the main made up our minds enemy of Festschriften may well baulk at refusing one to Walter Burkert, for there are few students whose paintings has been extra universally well known and applauded. at the celebration of his sixty fifth birthday in 1996 a gaggle of former students (Graf, Riedweg and Szlezák) and fellow students of Greek faith collected on the Römerstiftung René Clavel in Augst close to Basel to have a good time his success with a symposium.
