The extent to which piratical habits, and indeed all manner of robbing and violence, prevailed in these early periods, is very well known; but the reader will find some curious and startling instances in the work before us. Between foreign countries there was generally a species of private war being carried on; for it was an understood custom, that when a native of one country was injured by a native of another, and could get no redress, he was justified in obtaining what compensation or revenge he could from the fellow-countrymen of the person who had injured him. In such cases, his government granted him letters of marque--“license to _mark_, retain, and appropriate,” the men and goods of such foreign nation. Even on land the creditor of one foreigner, who could not get paid, might attach the goods of any other foreigner--of the same nation, we presume. It had to be enacted by Statute i. West. c. 23., that “no stranger who is of this realm shall be distrained in any town or market for a debt wherein he is neither principal nor security.”[14] Sir Harris Nicolas mentions a curious case at p. 235, which shows how rooted this idea must have been in the general mind, that the goods of all foreigners were liable for the debt of any one of them. One Richard de Canne had captured a ship in Brittany, and Helen, widow of Richard Clark, had lost a ship in Brittany; whereupon widow Helen laid claim to Richard’s ship, and got possession of it. But the king reversed the sentence of the justiciary of Ireland--“forasmuch that it does not appear to us to be just that the said Richard should lose the aforesaid ship, which he acquired in a land at war with us, on account of a ship which the said Helen afterwards lost in the same hostile land.” The present volume of Sir H. Nicolas’s history carries us no further than the reign of Edward II. We shall watch its future progress with interest. Hitherto we have to familiarise the imagination with ships or boats of very small dimensions, and their very limited exploits. And it is singular what an effort of the imagination it requires here to reduce sufficiently the scale of things. How complete is the contrast of that Saxon ship, with its one sail held by the hand, its few oars, its paddle at the quarter, and its sea-captain showing his dexterity in walking upon the oars while in motion, and throwing, like a conjuror, three darts in the air at once--with the stately man-of-war, and its calm and intelligent commander! Nothing can exhibit more strikingly than this contrast the gradual improvements which age after age may make and transmit. Mast has been added to mast, and sail to sail, and rope to rope; and in the hull, tier after tier of guns have been raised, till the ship has become the hugest and most complicated piece of mechanism the world has ever seen.
