The title of the album originates from a line in Hermann Hesse's book, Demian, quoted on the album's back cover: "We stood before it and began to freeze inside from the exertion. We questioned the painting, berated it, made love to it, prayed to it: We called it mother, called it whore and slut, called it our beloved, called it Abraxas...."
The album cover features the 1961 painting Annunciation by German-French painter Mati Klarwein. According to the artist, it was one of the first paintings he did after relocating to New York City. Carlos Santana reportedly noticed it in a magazine and asked that it be on the cover of the band's upcoming album. The cover is now considered a classic of rock album covers.
Rock critic Robert Christgau, in one of his capsule reviews in The Village Voice, at the time of the album's release, gave it a rating of only C+, which denotes "a not disreputable performance, most likely a failed experiment or a pleasant piece of hackwork."
