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.
