The Song of Songs is one of the three books of the Bible which tradition states were written by Solomon, whom it elsewhere depicts as a wise but sinful King of Israel.
Chronicling the courtship of an anonymous man and woman in the first-person, it has been read as an allegory for the loving relationship between God and his followers – albeit told with an unusual amount of vivid sexual innuendo. The words Freud recalls are from Chapter Five, as the song's female voice describes the body of her lover:
His legs are as pillars of marble, set upon sockets of fine gold
