1. The veil that got an artist accused of alchemy
Giuseppe Sanmartino carved the Veiled Christ from a single block of white marble in 1753 for the Cappella Sansevero in Naples.

2. Marble sits at 3-4 on the Mohs scale of hardness. Steel sits at 4 to 4.5.
Khafre Enthroned is made of anorthosite gneiss, which registers at 6 to 7. It was carved over four millennia ago by ancient Egyptians who, according to archaeologists, had not yet developed iron tools.
