“DIAGONAL WEAVING.”
I am unable to agree with a recently made statement published in The Labyrinth, Gerzeh and Marghuneh, by Prof. Flinders Petrie, E. A. Wainwright and E. Mackey, p. 6, which runs: “The fact of the weft not being at right angles to the warp, if one may conclude by the fabrics, does not, I think, imply that such weaving is of inferior quality. When I noticed the peculiarity first, I thought it might have arisen through distortion by stretching over the body, but repeated examples of the same fact have led me to consider other causes. We know how closely analogous to ‘darning’ was the early weaving; and in our days it is not unusual to find stockings not darned at right angles, and it may be the women weavers of old sometimes put in the weft more or less out of true right angle. In the childhood of weaving we should expect different methods, and it may be, seeing that we have no selvedged cloth until very long after this time, that they experimented with a diagonal weft to see if it would not reduce the tendency to fray out at the sides.” The amount the warp and weft are out of the right angle is stated to be about 20°. The specimen shown me under the microscope indicated clearly that the warp and weft were not at right angles and that the interstices were not square but diamond shaped.
It is possible to arrange the warp threads diagonally from beam to beam, but with continuous weft (that is in weaving so as to get selvedges) the weft has the tendency to slip up on one side and down on the other, hence the weaving is made laborious. With a separate weft for each pick, i.e., for every once the shed is opened, there is naturally not this tendency, but this alleged diagonally woven cloth frays just as easily as any other piece of cloth without selvedge, so in either case there is not only no advantage but distinct disadvantage taking the diagonal “beaming” into consideration. We must give the Egyptians credit for using the least laborious of two methods, that is if the second one were known to them.
Apparent diagonal weaving can be produced by anyone taking an ordinary piece of linen or cotton cloth, cutting off the selvedge and stretching the cloth in a direction diagonally to the direction of the warp and weft, and a piece of diagonally woven cloth is the result!
The probability is that the specimen of cloth, without a selvedge, having been stretched over the body for a long period of time, has, in the course of that time lost its nature and when removed it has retained its altered form and gives us the impression of having been woven diagonally.
