About Mons Porphyrites
Mons Porphyrites (Jabal Abu Duhhan) is the world's only imperial porphyry source, 950 m Red Sea mountain, producing purple leucocratic andesine porphyry monolithic columns and sarcophagus of Pantheon, Constantine's porphyry tomb and Augustus sarcophagi. Fortified villages Lykabettus and Porphyrites, temple of Serapis, watering stations and 150 km Wadi Hammamat road to Qena. Monopoly from 18 CE (Caius Cominius Leugas discovery per Pliny) to Diocletian. Exhaustion after 4th c. explains rarity.
