"Nicolò Marcello (c. 1399 – 1 December 1474) was the 69th Doge of Venice, elected in 1473. He held office for a short period, from 13 August 1473 to 1 December 1474. Said to have been inspired by a previous painting dating from the 15th century, Titian painted Nicolo Marcello´s portrait long after his death." - (en.wikipedia.org 23.11.2019)
