A previous post discussed several pieces of tubular knitting reported to have been made in Egypt during the 1st millennium CE. (Thanks to Matthew Pius for spotting the earlier studies and guest blogging their central details, summarized and commented on below.) One of the tubes had been radiocarbon dated to the interval 425–594 CE (in this test report) and is thus the oldest such object of substantiated age that has yet come to light. It is described by Dominique Bénazeth in an article titled “Accessoires vestimentaires dans la collection de textiles coptes du musée du Louvre” in a report from a conference in 2009, published in 2013 as Drawing the threads together; Dress accessories of the 1st millennium AD from Egypt.
The direct indications of this item having been made in Egypt are too weak to establish its provenance. However, its similarity to other knitted tubes that have a better-established Egyptian nexus — particularly one that is currently at the Museum of Byzantine Art in Berlin — was accepted as sufficient for grouping the Louvre piece with them. The Berlin tube is not clearly dated but is of certain geographic provenance and has been examined in greater structural detail. A report about it appears in an exhibition catalog from 2010 prepared by Klaus Finneiser, Petra Linscheid, and Meliné Pehlivanian, titled Georg Schweinfurth; Pionier der Textilforschung und Afrikaforscher. Their structural analysis concluded that it was likely to have been knitted on a peg loom, which is generally an efficient production device for tubular knitting. Since the Paris tube is both longer and narrower, the same method of production was assumed for it, as well.
The fabric structure of the Berlin tube is what a present-day knitter would call open (or uncrossed or untwisted) stocking stitch, albeit in a compound variant where each stitch is worked over the corresponding stitches in both of the two preceding courses (discussed and illustrated here). Loom knitters call this 1-over-2 (or double stitch) knitting. Its twisted “e-wrap” form commonly appears in stitch dictionaries of loom knitting, but descriptions of an open 1-over-2 structure produced with open “u-wrap” or “true” knitted stitches do not.
Compound knitting isn’t found in the established glossary of contemporary needle knitting but the structure appears in single-wale “false seams” worked with a crochet hook, such as Elizabeth Zimmerman’s phony seam (alternating 1-over-2 and 2-over-1). However, there is no particular difficulty in making compound stitches with ordinary knitting needles that justifies, much less necessitates, positing the greater utility of a knitting loom. There is no unequivocal physical or iconographic evidence of any of the candidate implements until significantly later than the production date of the Paris tube. There is also some basis for adding a circular needle to the speculative list of applicable tools.
An illustrated description of the needle-based technique was published in 1997 in a catalog prepared by Marianne Erikson titled Textiles in Egypt 200–1500 AD. It is part of the analysis of a fragment from ca. 1000 CE presented as flatwork but plausibly a segment of a piece worked in the round. That method of compound knitting was considered in further detail in a series of tutorial blog posts by Katrin Kania, in turn based on a workshop conducted by Petra Linscheid that examined the spool-based approach. A book recently published by Assia Brill titled Distitch, describes several needle-based techniques from the perspective of their contemporary application.
The photograph included in the Berlin report shows the compound structure from both the front and back of the fabric. The tube is not intact and several courses can be seen from the inside. The photograph in the report on the piece at the Louvre shows similar damage and reveals additional structural detail that might otherwise go unnoticed. Both tubes display the notable vertical compression of the individual stitches that is typical of compound knitting.
However, the second yellow band from the left in the lower segment in the following photo of the Paris tube has several stitches that are strained open and appear as though they might be looped into the immediately adjacent course only. The entire piece is close to two meters long and the full published photograph shows it in a serpentine position. The fineness of the stitching can be understood by visualizing the segments shown here as parts of a continuous tube of such length. If it is accepted that mistakes in this form of compound knitting can appear as ordinary knit stitches, there is no need for further explanation of the deviation in the lower segment.
The Berlin report references additional examples of Coptic tubular knitting and other sources include still more. Both simple and compound stocking stitch are represented and the detailed examination of a larger number of samples would permit a more certain determination of the balance between the two types. Some of the tubes are also closed at one end either with a drawstring or decreases in the final few rounds of stitches. The analysis of those structures might also provide more specific detail about the technique(s) applied to their production.
