Yes. There are also photographs and the testimony of the experts present.
There was no magic/invisible/cotton/patch there.
Yes. The so-called Lirey shroud; there are many, many others. But then, unlike you, I've done some actual research, and familiarised myself with (as an example) the developmental history of looms.
For those, unlike
@bobdroege7, who are interested in the herringbone pattern read on....
Firstly it's not actually ‘herringbone’. This is a common term used but to an expert, or someone who's bothered to Do The Research, it is in fact a ‘chevron’ weave.
This is one of those differences that is important to an expert but generally irrelevant to others. Basically it's down to the way the war and weft threads intersect; the warp threads run longitudinally along the length of the cloth while the weft threads run over and under the warp (in the case of the Lirey cloth this is under three warp threads, then over one, under three, over one, and repeat until it reaches the ‘spine’ of the sloth where the diagonals change direction.
In true ‘herringbone’ these 'ribs' are slightly off-set while in 'chevron' the two sets of ‘ribs’ attached to each ‘spine’ are exactly symmetrical.
Though of course this isn't actually true: an interesting fact is that the front of Lirey cloth is actually the back. this is down to the weaving process where lifting three-quarters of the warp threads at a time is awkward, heavy, and prone to tangling.
This back/front difference, with varied numbers of warp and weft threads, which are spun differently and hold colour differently, is noticeable if one examines the photographs taken for the 2002 shroud restoration, where the two can be easily differentiated.
- As an aside, this restoration, performed by textile experts, showed no invisible/magic/cotton patches. This should surprise no-one, except perhaps @bobdroege7.
Now, on to the prevalence of what I shall for convenience continue to call 'herringbone' twill. While shroudies and our own
@bobdroege7 like to cite Gilbert Raes as the be-all and end-all of textile expertise regarding the Lirey cloth there are problems. His examinations in 1973 were not based on an examination of the shole cloth, but only on tiny samples from it.
Remember the radiocarbon dating in 1988? The one that conclusive proved the medieval origin of the Lirey cloth> Well the shroud was examined in detail, both visually and microscopically then by Gabriel Vial (then General Secretary of the Centre International d’Étude des Textiles Anciens) as well as (remember her) Mechthild Flury-Lemberg. They were quite definite on the weave:
Vial was certain, and published, that the Lirey cloth had been woven on a four-shaft treadle loom. Moveover he was dismissive of those who had claimed to have found similar textiles from ancient times.
Let use weigh in with another expert. Donald King, who responded to the discussion in the various journals and describes fragment of printed cloth from the fourteenth century in the Victoria and Albert museum (probably Italian).
A number of art experts contributed as the herringbone weave is a feature of paintings, as the use of the four-shaft treadle loom allowed for wide cloth and hence larger surfaces to paint upon with less stitching together of canvas
- If you're interested any decent book on art history will cover this subject; Titian, in particular, frequently painted on herringbone patterned canvas but others (e.g. El Greco and Rembrandt) did so also.
Interestingly, the four-shaft treadle loom wasn't universally adopted but seems to have been popular in certain locations. There are hundreds of examples from parts of Germany (I recommend Hans-Jurgen Hundt's 'Die Textil-und Schnurreste' of 1981, in translation for those whose German is less fluent, as 'The Textile Cord and Residues'). He lists 129 herringbone/chevron pattern samples from Elisenhof and 28 from Hessens alone. Seven more from Haithabu are listed.
Conclusion
The Material of the Lirey cloth was woven on a four-shaft treadle loom in a chevron/herringbone pattern that was moderately common in the thirteen hundreds.
What is this nonsense supposed to mean? Are you denying the herringbone weave of the Lirey cloth? Are you denying there are extant examples fro the period?
