The story of the word

The purple in the name is the shellfish dye reserved for emperors. Imperial porphyry came from one place on earth, Mons Porphyrites in Egypt's Eastern Desert, worked from the first century AD, and Rome hauled it out for columns, basins and sarcophagi. Byzantine empresses gave birth in a chamber lined with it, so an heir born to a reigning emperor was πορφυρογέννητος, born in the purple. The Four Tetrarchs on the corner of St Mark's in Venice are carved from it.
