The band eventually jettisoned the name Earth in favour of the title of a 1963 horror film starring Boris Karloff. In turn, Sabbath soon became synonymous with the crucifix, with an inverted cross appearing inside the sleeve of their self-titled first album.
In addition, all four members began wearing large aluminium crosses around their necks made by Ozzy's dad. This wasn't a fashion statement, and contrary to any accusations that they were dealing in black magic, the opposite was true - they were fending off a witch's spell.
The band asked were asked to play a gig at Stonehenge celebrating the Witches' Sabbath. They refused and 'King Of The Witches' Alex Sanders placed a hex on them. The crosses were Sabbath's way of protecting themselves, but the crucifix connection has lasted to this day. Iommi still wears one onstage and they often appear on the band's merchandise.
