The Development of the Loom

Webster defines a loom as "a frame or machine for interweaving yarn or threads into a fabric, the operation being performed by laying lengthwise a series called the warp and weaving in across this other threads called the weft, woof, or filling." Another definition, which is quite to the point: "A loom is the framework across which threads are stretched for the weaving of cloth." Since the warp functions as the backbone of the weaving structure, choosing a warp requires knowledge of the nature of fibers, in that warp yarns workbest if they have certain characteristics. The warps should be fairly smooth and should not have too many slubs or bumps. The warps should be plied yarns with adequate tensile strength, strong enough to withstand a certain amount of weight. Types of warp yarns used in historic times varied depending upon what plants or animals were native to a particular region. Cotton, wool, linen, and silk were favorite warp yarns of our ancestors and are still some of the most popular choices of contemporary weavers. Today's fiber artists use the same general principles as people during primitive times, for the fundamental aspects of handweaving have remained unchanged. Since many loom types have evolved over the centuries, we will discuss a selection of looms, starting with the simple and progressing to the more complex.

Weaving in Switzerland

Another area where artifacts of prehistoric weaving were found was the region of the Swiss Lake Dwellers, a culture dating back to about 5000 B.C.E. Here archeologists discovered woven linen scraps and spinning whorls, an indication that this culture had advanced knowledge of the subject.

Weaving in China

One of the most fascinating stories in the development of weaving comes from China. Several legends have been told about the discovery of silk, but there is one that has become the most noted of all. In the 27th century B.C.E., during the reign of Emperor Huang-Ti, a disease began to destroy the trees in the royal mulberry grove, so the emperor asked his empress to study the problem. Empress Hsi-Ling-shi spent time in the groves and noticed that small white worms were devouring the mulberry leaves. The worms then would crawl to the naked stems below where they would spin silvery, white cocoons. According to legend, Empress His-Ling-shi took some of the small cocoons to her apartment for closer observation, and there one of the cocoons accidentally fell into a bath of warm water. As water was absorbed into the cocoon, the tiny pocket began to unravel revealing a delicate network of fibers. The empress pulled a small filament from the network and realized the fiber was a continuous thread, hundreds of feet long. In fact, one cocoon can contain a single filament measuring over 1,000 yards. With the discovery of the silk fiber, His-Ling-shi found the secret of acquiring a very rare and exquisite thread, one that could be used without first going through the spinning process.

As weavers in China began using silk in many of their elegant garments and tapestries, and later, as fabrics began to be exported, people outside of China became envious and somewhat resentful of the discovery. Despite the interest and curiosity of others, the process of cultivating silk remained a mystery and a well-kept secret to the outside world for over 3000 years.

Weaving among the ancient Hebrews

Ancient fabrics from the Hebrew world date back as early as 3000 BC. Many of the yarns produced by the Hebrews were multi-plied, up to 72 ply, and the Bible indicates that some garments contained threads made of gold and silver. Wool was used more than any other fiber in this area, white wool being the finest. Course wool, black wool, and horsehair were considered secondary. Hebrew priests were required to wear pure linen. In the Old Testament (Deuteronomy 22:11), we are given detailed information about the practices of early Hebrew weaving. One law stated that it was prohibitive to wear fabrics made from a mixture of linen and wool fibers. Another Hebrew law forbade married women to spin yarn in public places or to spin yarn at night by moonlight. Because of the active nature of the spinning process, such an act might reveal a woman's arms, and if this were to occur, it would give a husband the right to divorce his wife.

Weaving in Mesopotamia

Mesopotamia, located between the Tigris and Euphrates rivers, became the center for commerce and was known to have textiles of quality. Because of its location, Mesopotamia was a major pathway for trade and for other developing civilizations. Archeologists found Sumerian clay tablets dating back to 2200 BC, which provided evidence of a flourishing weaving industry. The Babylonians followed with weavers who specialized in certain areas of the craft. For example, embroidery became such an important textile art form to this culture that the technique came to be known as "Babylonian".

Weaving in Egypt

Sealed tombs in Egypt's Nile Valley have brought forth fabrics dating back as far as 5000 BC. The predominant fiber found in Egypt was linen, a product of the native flax plant. A simple plain-weave pattern, an over-under stitch, was used for the construction of cloth. This plain weave structure was the dominant stitch until about 2500 BC. Wool was accessible in Egypt, as well, but was considered a fiber of the lower classes, namely, herdsmen and farmers.

Wool garments are rarely found in Egyptian tombs. In fact, Egyptian law placed certain restrictions on the use of wool. One such law forbade members of the priesthood to wear wool next to their skin or to wear wool into a place of worship. Cloth make from wool was thought to be crude and irreverent. Fabric made with cotton was much more acceptable and has been found in Egyptian tombs, but cloth made with linen was always considered the highest quality material and was used in mummy wrappings of the aristocracy.

The Prehistoric Origins of Weaving

With modern sophisticated methods of radiocarbon testing and DNA testing, today's scientists are much better able to assign accurate dates to archeological findings than they were even a decade ago. The exact date of the first handwoven works, however, continues to remain a mystery. Nevertheless, there is evidence of cloth being made in Mesopotamia and in Turkey as far back as 7000 to 8000 BC.

Since fabric remnants have been difficult to find, to say the least, some historians use other sources as guides in piecing together our textile heritage. One valued artifact is the funerary model of a weaver's workshop, which was found in an Egyptian tomb. This model contains a horizontal loom, warping devices and other tools, and weavers in action. We can also take note of the garments worn by the people.

Another artifact, which is highly valued, is the piece of pottery below with the imprint of a textile structure etched in its exterior. It is believed that an early craftsperson formed this pot by lining the interior of a woven basket with wet clay. Heat was provided to shrink and harden the clay, at which time, the basket fell away leaving its mark on the outside of the pot.
