All the portraits of this lad are full of charm.

He was heir to the throne, but died in boyhood.
[Illustration: DON BALTHAZAR CARLOS From the picture by Velasquez, in the Prado Museum, Madrid] Velasquez paid another visit to Italy, twenty years after his first, for the purpose of buying more pictures to adorn Philip's palaces.
Again we find him in Venice, where he bought two Tintorets and a Veronese, and again he made a long stay in Rome, this time to paint the portrait of the Pope.

When he returned to Spain in 1651 he had still nine years of work before him.

There were portraits of Philip's new Queen to be painted--a young girl in a most uncomfortable dress--and portraits of her child, the Infanta Marguerita.

Bewitching are the pictures of this little princess at the ages of three, of four, and of seven, with her fair hair tied in a bow at the side of her head, and voluminous skirts of pink and silver.
