Palomino relates that a superb eagle, of the bearded kind, having been
captured in the royal chase, near the Prado, the king (Philip III.) gave
orders to Pantoja to paint its likeness, which he did with such
truthfulness that the royal bird, on seeing it, mistook it for a real
eagle, and attacked the picture with such impetuosity that he tore it in
pieces with his beak and talons before they could secure him. The
indignant bird was then tied more carefully, and the portrait painted
over again.
