Knots, Splices and Rope Work 

The history of ropes and knots is so dim and ancient that really little is known of their origin. That earliest man used cordage of some kind and by his ingenuity succeeded in tying the material together, is indisputable, for the most ancient carvings and decorations of prehistoric man show knots in several forms. Doubtless the trailing vines and plants first suggested ropes to human beings; and it is quite probable that these same vines, in their various twistings and twinings, gave man his first idea of knots.

Since the earliest times knots have been everywhere interwoven with human affairs; jugglers have used them in their tricks; they have become almost a part of many occupations and trades, while in song and story they have become the symbol of steadfastness and strength.
