Spanish painter. He is first certainly documented in 1506 in Valencia, where he collaborated with Fernando Llanos (active 1506–16) in painting twelve large panels of the Life of the Virgin for the main altarpiece of the cathedral (1507–10). From the style of these paintings it is overwhelmingly likely that the ‘Ferrando Spagnuolo’ who in 1505 is recorded in Florence assisting Leonardo da Vinci on the Battle of Anghiari was either Yáñez or Llanos. They were ‘the first non-Italian painters to assimilate the style of the High Renaissance and practice it in a foreign land’ (Jonathan Brown, Painting in Spain: 1500–1700, 1998). Their respective shares in the altarpiece are a matter of debate, although there is a tendency now to see Yáñez as the more gifted. Various other paintings are attributed to each of them working independently, but their careers are ill-defined.
