 One half-hour of each class was devoted to a lecture (complete with handouts and homework assignments), the other half-hour to an Arkestra performance or Sun Ra keyboard solo.Reading lists included the works of Madame Blavatsky and Henry Dumas, the Tibetan Book of the Dead, Alexander Hislop's "The Two Babylons", The Book of Oahspe, and assorted volumes concerning Egyptian hieroglyphs, African American folklore, and other topics.In 1971, Sun Ra traveled throughout Egypt with the Arkestra at the invitation of the drummer Salah Ragab.
