Secretum (British Museum)
The Secretum (Latin for 'hidden away') was a British Museum collection of the nineteenth and early twentieth centuries that held artefacts and images deemed sexually graphic. Many of the items were amulets, charms and votive offerings, often from pre-Christian traditions, including the worship of Priapus, a Greco-Roman god of fertility and male genitalia.
