"The initiation ceremonies, the boodo hut of the falconer, the noises in the magic dark, the necromantic knots. Knots were probably the earliest spell. The two hawks consider themselves spell-bound to their blocks by my arts . . . I am convinced that if nobody had ever invented knots, nobody would ever have imagined magicians."
(I bought myself "The Handbook of Knots" by Des Pawson for my birthday this year, and have been practicing knots. There is certainly a magic between the steps and the resulting knot.)
