A pair of porphyry urns and covers, Roman, 17th Century.

Porphyry is a type of igneous rock, the term itself deriving from Ancient Greek, meaning purple.

Purple was an imperial colour and the deep purple, so called ‘imperial’ porphyry, came to be widely used for tombs and monuments in Ancient Rome.

The rock itself was thought to be the hardest in antiquity.
