A great portion of the large sums spent by Buckingham in Spain was expended in forming that famous collection which fell, unhappily, into the hands of his son. It would appear that James I. somewhat curtailed Charles’s expenditure on this head; for we find, by an entry in the State Paper Office, that Buckingham lent the Prince twelve thousand pounds during their sojourn in Spain. Nevertheless, no specimen of Spanish art was ever conveyed to England by Charles.[147] A sketch was, indeed, begun of the Prince, by Velasquez, but it is doubtful if it were ever completed. Pachecho, the father-in-law of Velasquez, states that Charles was so delighted with this portrait in its unfinished state, that he presented the great painter with a hundred thousand crowns.[148] One may readily account for its never being completed, because Velasquez, when Charles and Buckingham left Madrid, could scarcely have finished the portraits and other pictures on which he was engaged by Philip IV.

In 1847, a picture belonging to Mr. Saare, of Reading, and supposed to have been a relic of the gallery of Whitehall, was exhibited in London as this lost portrait by Velasquez. It portrays Prince Charles in a more robust form, and with a greater breadth of countenance than any other known resemblance; and was stated to have been painted in 1623, and to have been mentioned in a privately printed catalogue of the gallery of the Earl of Fife, who died in 1809, in which it was stated that it had once belonged to the Duke of Buckingham. Unfortunately, the surname of the Duke of Buckingham was not specified; and since the title has been owned, so late as 1735, by the Sheffield family, the evidence was incomplete. A very curious controversy ensued, but facts remain much in the same state as before; and the authenticity of the portrait has been strongly disputed, if not denied, by Dr. Waagen, and others. It is singular that there was no work of Velasquez among the pictures left by Buckingham.
