Funny enougth there wasnt, it all happened a few years later with the Prusick knots getting a sling [rope in a circle] putting 2 loops round the main rope then you could put your feet in it and using 2, could climb the rope.Now with the clamps its easy. A pal of mine it happened to in the Dolamites on the Yellow Edge Alan Evans Bless Him. It was after that everyone in England learned how to Prussick. Alan came off on an overhang and they couldnt get him up. The Red Sqiurrels Italian Giudes cut Him Down, it was bad for the Tourist Trade .
