Didn't the Italians steal the body of Saint Nicholas from Myra, not long after the Great Schism?
"Some of the main points in his legend are as follows: He was born at Parara, a city of Lycia in Asia Minor; in his youth he made a pilgrimage to Egypt and Palestine; shortly after his return he became Bishop of Myra; cast into prison during the persecution of Diocletian, he was released after the accession of Constantine, and was present at the Council of Nicaea. In 1087 Italian merchants stole his body at Myra, bringing it to Bari in Italy."
