I heard of this knot today while reading Moby Dick; it appears in chapter 47, The Mat-Maker. Your video was the first resource I found while trying to figure out what a sword-mat actually is, and it's a great video, coming from someone who has difficulties with visual processing. This passage from Moby Dick weaves some rich symbolism into the sword-mat that you might appreciate: Queequeg and I were mildly employed weaving what is called a sword-mat, for an additional lashing to our boat. So still and subdued and yet somehow preluding was all the scene, and such an incantation of reverie lurked in the air, that each silent sailor seemed resolved into his own invisible self. I was the attendant or page of Queequeg, while busy at the mat. As I kept passing and repassing the filling or woof of marline between the long yarns of the warp, using my own hand for the shuttle, and as Queequeg, standing sideways, ever and anon slid his heavy oaken sword between the threads, and idly looking off upon the water, carelessly and unthinkingly drove home every yarn: I say so strange a dreaminess did there then reign all over the ship and all over the sea, only broken by the intermitting dull sound of the sword, that it seemed as if this were the Loom of Time, and I myself were a shuttle mechanically weaving and weaving away at the Fates. There lay the fixed threads of the warp subject to but one single, ever returning, unchanging vibration, and that vibration merely enough to admit of the crosswise interblending of other threads with its own. This warp seemed necessity; and here, thought I, with my own hand I ply my own shuttle and weave my own destiny into these unalterable threads. Meantime, Queequeg’s impulsive, indifferent sword, sometimes hitting the woof slantingly, or crookedly, or strongly, or weakly, as the case might be; and by this difference in the concluding blow producing a corresponding contrast in the final aspect of the completed fabric; this savage’s sword, thought I, which thus finally shapes and fashions both warp and woof; this easy, indifferent sword must be chance-aye, chance, free will, and necessity-nowise incompatible-all interweavingly working together. The straight warp of necessity, not to be swerved from its ultimate course-its every alternating vibration, indeed, only tending to that; free will still free to ply her shuttle between given threads; and chance, though restrained in its play within the right lines of necessity, and sideways in its motions directed by free will, though thus prescribed to by both, chance by turns rules either, and has the last featuring blow at events.
I also came to watch this video for the same reason. Read through your entire comment and so I'll skip the relevant passages and move on 😂 hope you enjoyed the book, this is my first time reading this beast and I'm having a great time
