The Tucson artifacts, sometimes called the Tucson Lead Crosses, Tucson Crosses, Silverbell Road artifacts, or Silverbell artifacts, were thirty-one lead objects that Charles E. Manier and his family found in 1924 near Picture Rocks, Arizona, that were initially thought by some to be created by early Mediterranean civilizations that had crossed the Atlantic in the first century, but were later determined to be a hoax.[1][2]
The find consisted of thirty-one lead objects, including crosses, swords, and religious/ceremonial paraphernalia, most of which bore Hebrew or Latin engraved inscriptions, pictures of temples, leaders' portraits, angels, and a dinosaur (inscribed on the lead blade of a sword). One contained the phrase "Calalus, the unknown land", which was used by believers as the name of the settlement. The objects also have Roman numerals ranging from 790 to 900 inscribed on them, which were sometimes interpreted to represent the date of their creation. The site contains no other artifacts, no pottery sherds, no broken glass, no human or animal remains, and no sign of hearths or housing.[3][1]
