The Tomb of Orcus (Italian: Tomba dell'Orco), sometimes called the Tomb of Murina (Italian: Tomba dei Murina), is a 4th-century BC Etruscan hypogeum (burial chamber) in Tarquinia, Italy. Discovered in 1868, it displays Hellenistic influences in its remarkable murals, which include the portrait of Velia Velcha, an Etruscan noblewoman, and the only known pictorial representation of the demon Tuchulcha. In general, the murals are noted for their depiction of death, evil, and unhappiness.
Because the tomb was built in two sections at two stages, it is sometimes referred to as the Tombs of Orcus I and II; it is believed to have belonged to the Murina family, an offshoot of the Etruscan Spurinnae. The foundation is inscribed with the following enigmatic phrase:
Orcus I was built between 470 and 450 BC (perhaps by a man named Leive; see below); a separate hypogeum, Orcus II, was built c. 325 BC. At some point in antiquity the wall between the two was removed, creating a large tomb with two (entrances).
The tomb was excavated in 1868 by an officer of the French Army. Upon its discovery, the excavator mistook the painting of a cyclops for the Roman god Orcus (see below), hence the name "Tomb of Orcus". The Italian name (Tomba dell'Orco) can also mean "Tomb of the Ogre", and it is used that way in Italy today.
The second tomb has never been fully excavated.
Though most of the walls are muraled, the artists did not complete the ceiling. A scientific analysis in 2001 revealed that the paint used contained cinnabar, ochre, orpiment, calcite, copper, and Egyptian blue. While the artwork in Orcus I is highly praised (particularly the painting of Velia Velcha; see below), some of the artwork of Orcus II is considered poorly done.
