Son and heir of Sir Rowland de Boys, who hated his youngest brother Orlando, and persuaded him to try a wrestling match with a professed wrestler, hoping thus to kill his brother; but when Orlando proved victorious, Oliver swore to set fire to his chamber when he was asleep. Orlando fled to the forest of Arden, and Oliver pursued him; but one day, as he slept in the forest, a snake and a lioness lurked near to make him their prey; Orlando happened to be passing, and slew the two monsters. When Oliver discovered this heroic deed he repented of his ill-conduct, and his sorrow so interested the Princess Celia that she fell in love with him, and they were married. (Shakespeare: As You Like It.)
