In the reign of the famous King Arthur there lived in Cornwall a lad named Jack, who was a boy of a bold temper, and took delight in hearing or reading of conjurers, giants, and fairies, and used to listen eagerly to the deeds of the knights of King Arthur’s Round Table.

In those days there lived on St. Michael’s Mount, off Cornwall, a huge giant, eighteen feet high and nine feet round, his fierce and savage looks were the terror of all who beheld him.

He dwelt in a gloomy cavern on the top of the mountain, and used to wade over to the mainland in search of prey; when he would throw half-a-dozen oxen upon his back and tie three times as many sheep and hogs round his waist, and march back to his own abode.

The giant had done this for many years when Jack resolved to destroy him.
