Hieroglyphics of Horapollo, tr. Alexander Turner Cory, [1840], at sacred-texts.com
When they would symbolise a woman that hates her own husband, and designs his death, and is complaisant only during intercourse, they delineate a VIPER; for when in connexion with the male, she places his mouth in her mouth, and after they have disjoined, she bites the head of the male and kills him.
