Answer
Priam's Treasure was discovered by Heinrich Schliemann during his excavations at the site of Troy. The treasure, which included gold, silver, and jewelry, was found in a large copper chest and is believed to have belonged to King Priam, the legendary ruler of Troy. Schliemann's discovery of Priam's Treasure provided significant evidence to support the historicity of the Trojan War and the accuracy of Homer's Iliad.
