Another great release on Rise Above, the first album from US Doom-lords Revelation. The three formats of the original release feature different images beside the cover, which are listed below.
Cover image, all formats: detail from the East Frieze of the Pergamon Altar, depicting Athena battling the giant Alkyoneus.
CD back inlay: skull carving, source unknown
LP back cover: Gothic tracery, possibly the inside of a spire, source unknown
LP insert: flying buttresses, Reims Cathedral, France
Cassette inlay - tracklist panel: Maze from Reims Cathedral, France
Cassette inlay - inside: Stone angel, source unknown. This image was also used by dark ambient group Funerary Call on their 1994 demo "A Comselh De Ors", and also features inside the inlay for Godflesh's "Pure" CD. I would love to know the source of the image.
And here's another album cover from the same band; a carving of Adam and Eve from the cathedral at Orvieto in Italy.
