After 80 years of being passed around by smugglers, a precious limestone relief is heading home to modern-day Iran, formerly part of the Persian Empire. The carved piece of stone shows a Persian Imperial guard holding a spear. It was once part of a balustrade in ancient Persepolis. Experts say it was made between 510 and 330 BCE, during the Achaemenid dynasty. In 1936, it was reported stolen from Iran. In 2011, it was stolen from the Montreal Museum of Fine Art. In October 2017, it was confiscated at the Park Armory in New York, where someone was trying to sell it.
