The arches of the Romanesque portal are beautifully ornamented, in a manner suggestive of Arab influence; the bronze doors, executed by Barisanus of Trani in 1175, rank among the best of their period in southern Italy.
That on the north is by Barisanus of Trani in southern Italy, an artist probably of Greek origin.
It is inscribed Barisanus Tran.
The door by Barisanus is probably of about the same time, as other examples of his work with inscribed dates show that he was a contemporary of Bonannus.
Pantaleo, almost entirely modernized, has fine bronze doors by Barisanus of Trani (1179), and two pulpits in Cosmatesque work.
