Portrait of Isabella of Portugal (van der Weyden)

Executed around 1450, the painting had been attributed to Rogier van der Weyden,[1] but is now believed to be from a member of his workshop.

She is dressed in an ornately decorated red and gold brocade dress, tightly pulled below at her waist by a green sash, although the artist did not match the brocade pattern on the sleeves.

[2] On the upper right is the inscription PERSICA SIBYLLA IA, which suggests it may have been one of a series of portraits depicting sibyls, an identity which contrasts with Isabella's.

It may have belonged to Alexandre d'Arenberg, Duke of Croy and Prince of Chimay, from the end about 1590 to 1629.

It was bought by a dealer in 1883 and later sold to Adolph Carl de Rothschild a few years later; when he died in 1900, his son, Baron Maurice de Rothschild inherited the painting, and sold it to John D. Rockefeller in 1927.
