Testicles

When Bloom is invested as Lord Mayor, Magistrate, Chairman, President, King, Emperor, Pope, and Messiah, he swears an oath of office while "Placing his right hand on his testicles." The business of swearing sacred oaths on the family jewels may appear to be one more of Circe's wild spontaneous fantasies, but in fact it was practiced by ancient Hebrews, and probably also by Romans. There may even be Irish historical analogues.
