Solomon's knot

Solomon's knot is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Solomon's knot rather than just read about it. In short: Solomon's knot (Latin: sigillum Salomonis, lit. 'Solomon's seal') is a traditional decorative motif used since ancient times, and found in many cultures. Despite the name, it is classified as a link, and is not a true knot according to the definitions of mathematical knot theory.

Key takeaways

  • Solomon's knot belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Solomon's knot to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Solomon's knot from memory before moving on to harder problems.

Reference excerpt

Solomon's knot (Latin: sigillum Salomonis, lit. 'Solomon's seal') is a traditional decorative motif used since ancient times, and found in many cultures. Despite the name, it is classified as a link, and is not a true knot according to the definitions of mathematical knot theory.

Structure

The Solomon's knot consists of two closed loops, which are doubly interlinked in an interlaced manner. If laid flat, the Solomon's knot is seen to have four crossings where the two loops interweave under and over each other. This contrasts with two crossings in the simpler Hopf link. In most artistic representations, the parts of the loops that alternately cross over and under each other become the sides of a central square, while four loopings extend outward in four directions. The four extending loopings may have oval, square, or triangular endings, or may terminate with free-form shapes such as leaves, lobes, blades, wings etc.

Occurrences

The Solomon's knot often occurs in ancient Roman mosaics, usually represented as two interlaced ovals. Sepphoris National Park, Israel, has Solomon's Knots in stone mosaics at the site of an ancient synagogue. In Africa, Solomon's knot is found on glass beadwork, textiles, and carvings of the Yoruba people. When the knot appears in this culture, it often denotes royal status; thus, it is featured on crowns, tunics, and other ceremonial objects. Across the Middle East, historical Islamic sites show Solomon's knot as part of Muslim tradition. It appears over the doorway of an early twentieth century CE mosque/madrasa in Cairo. Two versions of Solomon's knot are included in the recently excavated Yattir Mosaic in Jordan. To the east, it is woven into an antique Central Asian prayer rug. To the west, Solomon's knot appeared in Moorish Spain, and it shines in leaded glass windows in a late twentieth century CE mosque in the United States. The British Museum, London, England has a fourteenth-century CE Egyptian Qur'an with a Solomon's Knot as its frontispiece. University of California, Los Angeles Fowler Museum of Cultural History has a large African collection that includes nineteenth and twentieth century CE Yoruba glass beadwork crowns and masks decorated with Solomon's Knots. Home of Peace Mausoleum, a Jewish Cemetery, Los Angeles, has multiple images of Solomon's knot in stone and concrete bas reliefs sculpted 1934 CE. Saint Sophia's Greek Orthodox Cathedral, "Byzantine District" of Los Angeles has an olive wood Epitaphios (bier for Christ) with Solomon's knots carved at each corner. The Epitaphios is used in the Greek Easter services. Powell Library University of California, Los Angeles has ceiling beams in the Main Reading Room covered with Solomon's Knots. Built in 1926 CE, the reading room also features a central Dome of Wisdom bordered by Solomon's knots.

Name In Latin, this configuration was sometimes known as sigillum Salomonis, meaning literally 'seal of Solomon'. It was associated with the Biblical monarch Solomon because of his reputation for wisdom and knowledge (and in some legends, his occult powers). This phrase is usually rendered into English as "Solomon's knot", since "seal of Solomon" has other conflicting meanings (often referring to either a Star of David or pentagram). In the study of ancient mosaics, the Solomon's knot is often known as a "guilloche knot" or "duplex knot", while a Solomon's knot in the center of a decorative configuration of four curving arcs is known as a "pelta-swastika" (where pelta is Latin for "shield"). Among other names currently in use are the following:

"Foundation Knot" applies to the interweaving or interlacing which is the basis for many elaborate Celtic designs, and is used in the United States in crochet and macramé patterns. "Imbolo" describes the knot design on the textiles of the Kuba people of Congo. Nodo di Salomone is the Italian term for Solomon's knot, and is used to name the Solomon's knot mosaic found at the ruins of a synagogue at Ostia, the ancient seaport for Rome.

Worked examples

Example 1 — a first encounter with Solomon's knot

Start with the simplest possible case. Write down what Solomon's knot claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Solomon's knot before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Solomon's knot ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Solomon's knot

In research
Solomon's knot appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Solomon's knot in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Solomon's knot is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alternating knots and links, Decorative knots, Knot theory, so understanding it makes those chapters shorter.
In everyday life
Look for Solomon's knot outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
