Ptolemaic Terrascope is a magazine covering old and new music, usually of a psychedelic nature. It has been published irregularly since 1989. Issues typically come with a 7" vinyl record or latterly a CD, and sometimes also special inserts such as artwork, scrap books, and discount coupons.
According to the magazine, the name Ptolemaic Terrascope has no real meaning. Their official web page explains, "Ptolemy is a tortoise who lives at Terrascope Towers. Terrascope is a word Phil made up because (a) it matched the artwork we'd designed for the first issue, and (b) we like the Captain Beefheart song 'Tarotplane'." (Absolute Astronomy)
