Nicolò d'Arcano (1637 – 1 January 1714) was a Roman Catholic prelate who served as Bishop of Comacchio (1670–1714).[1]
Nicolò d'Arcano was born in Cesene, Italy in 1637 and ordained a priest on 9 November 1670.[2] On 22 December 1670, he was appointed during the papacy of Pope Clement X as Bishop of Comacchio. On 4 January 1671, he was consecrated bishop by Marcello Santacroce, Bishop of Tivoli, with Pier Antonio Capobianco, Bishop Emeritus of Lacedonia, and Andrea Tamantini, Bishop of Cagli, serving as co-consecrators. He served as Bishop of Comacchio until his death on 1 January 1714.
