Caiaphas Ossuary Recreation full size (resin cast). About 29 inches long by 12 inches wide by 17 inches tall. The Caiaphas ossuary is a bone box that archaeologists believe may have belonged to Joseph, son of Caiaphas, known as the High Priest Caiaphas in the New Testament. Biblical scholars argued against the historicity of such a person, but this ossuary attributed to him was found in Jerusalem in 1990.
