The cathedral also contains a well-known marble statue of Saint Euphemia. This has been attributed by some critics to Mantegna, and was exhibited as his at Mantua in 2009.[2][3] Others however, including Giovanni Agosti, curator of the Mantegna exhibition at the Louvre, attribute it to Pietro Lombardo.[4][5] The discussion continues.[6]
The festival of Saint Euphemia, patron of Irsina, takes place on 14–17 September. On 16 September the keys of the city are offered to the archbishop on the altar of the cathedral, and by him to Saint Euphemia. A long procession then takes place through the streets of the town carrying the statue of the saint, the reliquary containing her arm and the icon of Our Lady of Divine Providence.
