Juan de Flandes.

He was an Early Netherlandish painter who was active in Spain from 1496 to 1519; his actual name is unknown. He was born around 1460 in Flanders (modern Belgium)

He is only documented after he became an artist at the court of Isabella I of Castile in Spain, where he is first mentioned in the accounts in 1496, and described as "court painter" by 1498, continuing in her service until her death in 1504. He mostly painted accomplished portraits of the royal family, but also most of a large group of small panels for a polyptych altarpiece for Isabella, now widely dispersed with the largest group of panels in the royal collection in Madrid.
