The only touch of manhood for King Charles II was a taste for shooting which he occasionally indulged in the preserves of the Escorial.

Official documents generally bear a facsimile of his signature and not the original.
During his reign, the Spanish court considered Charles II as an obstruction in the affairs of state and an unimportant figure with almost no power.
