 Lapis Lazuli

History & Interesting Facts:

The beautiful blues in paintings from the Renaissance are thanks to the blue of lapis lazuli, the blue rock loved by the ancients, from Mesopotamia, to Egypt, to Persia, to Greece and Rome. The name is international, from the Latin, lapis, which means stone, and from the Arabic, azul, which means blue. When lapis was first introduced to Europe, it was called ultramarinum, which means beyond the sea. Ground lapis was the secret of the blue in ultramarine, the pigment which painters used to paint the sea and the sky until the nineteenth century. Lapis was also popular in inlays. The columns of St. Isaac’s Cathedral in Petersburg are lined with lapis and the Pushkin Palace in Petersburg has lapis lazuli paneling!

Mythology & Lore:

The Romans believed that lapis was a powerful aphrodisiac. In the Middle Ages, it was thought to keep the limbs healthy and free the soul from error, envy and fear. Lapis is a dark blue microcrystalline rock composed primarily of the mineral lazurite.
