Triquetra
Template:Short description Template:EngvarB Template:Use dmy dates Template:About
The triquetra (Template:IPAc-en Template:Respell; from the Latin adjective triquetrus "three-cornered") is a triangular figure composed of three interlaced arcs, or (equivalently) three overlapping vesicae piscis lens shapes. It is used as an ornamental design in architecture, and in medieval manuscript illumination (particularly in the Insular tradition). Its depiction as interlaced is common in Insular ornaments from about the 7th century. In this interpretation, the triquetra represents the topologically simplest possible knot.
HistoryEdit
Template:More citations needed section
Iron AgeEdit
The term triquetra in archaeology is used of any figure consisting of three arcs, including a pinwheel design of the type of the triskeles. Such symbols become frequent from about the 4th century BC ornamented ceramics of Anatolia and Persia, and it appears on early Lycian coins.<ref>John Burley Waring, Ceramic Art in Remote Ages (1874), 84f.</ref>
The triquetra is found on runestones in Northern Europe, such as the Funbo Runestones, and on early Germanic coins.Template:Cn It bears a resemblance to the valknut, a design of three interlacing triangles, found in the same context.
Insular artEdit
The triquetra is often found in insular art, most notably metal work and in illuminated manuscripts like the Book of Kells. It is a "minor though recurring theme" in the secondary phase of Anglo-Saxon sceatta production (c. 710–760).<ref name=Abramson1>Tony Abramson (ed.), Two Decades of Discovery Studies in Medieval Coinage 1, Boydell Press (2008), p. 1.</ref> It is found in similar artwork on early Christian High Crosses and slabs. An example from early medieval stonework is the Anglo-Saxon frithstool at Hexham Abbey.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The symbol has been interpreted as representing the Holy Trinity, especially since the Celtic revival of the 19th century. The original intention by the early medieval artists is unknown and expertsTemplate:Who? warn against over-interpretation.<ref name=Abramson1/> It is, however, regularly used as a Trinitarian symbol in contemporary Catholic iconography.
Buddhist traditionEdit
The triquetra has been a known symbol in Japan called Musubi Mitsugashiwa.Template:Citation needed Being one of the forms of the Iakšaku dynasty signs, it reached Japan with the dynasty's Kāśyapīya spreading technology and Buddhism via the Kingdom of Khotan, China, and Korea.Template:Citation needed
Modern useEdit
The triquetra is often used artistically as a design element when Celtic knotwork is used, especially in association with the modern Celtic nations. The triquetra, also known as an "Irish Trinity Knot", is often found as a design element in popular Irish jewelry such as claddaghs and other wedding or engagement rings.<ref>McMahon, Seán (1999). Story of the Claddagh Ring. Mercier Press. Template:ISBN.</ref>Template:Page missing Some Christians use the triquetra as a symbol for the Trinity.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Celtic pagans or neopagans who are not of a Celtic cultural orientation may use the triquetra to symbolise a variety of concepts and mythological figures. Due to its presence in insular Celtic art, Celtic Reconstructionists use the triquetra either to represent one of the various triplicities in their cosmology and theology (such as the tripartite division of the world into the realms of Land, Sea, and Sky),<ref name="Mac Mathúna">Mac Mathúna, Liam (1999) "Irish Perceptions of the Cosmos" Celtica vol. 23 (1999), pp.174–187</ref> or as a symbol of one of the specific Celtic triple goddesses – for example the battle goddess, The Morrígan. The symbol is also sometimes used by Wiccans, White Witches, and some New Agers to symbolise the Triple Goddess, or as a protective symbol.<ref name="scott-cunningham">Template:Citation.</ref>
In the 1998–2006 American fantasy drama Charmed, that ran on the now-defunct The WB network, the triquetra was prominently used as a symbol on the Halliwells' Book of Shadows, the book of spells, potions, and other information the sisters used to fight evil. The triquetra was also used as a symbol of the Charmed Ones and their collective Power of Three. The triquetra on the Book of Shadows would be seen to fracture and pull apart when their bond was temporarily broken by a demon. It was also featured prominently in the opening credits of each episode throughout its eight-season run. The symbol was also used in the 2018 reboot that ran on The CW.
In the TV series The Walking Dead (2010), Michonne's katana features a triquetra, chosen for its meaning as a "triple goddess symbol".<ref name=EW>Template:Cite magazine</ref><ref name=USAtoday>Template:Cite news</ref>
In the German Netflix series Dark (2017), it symbolizes the caves' closed time loops with each loop being 33 years apart, with the past affecting the future and the future influencing the past. The Triquetra is of significant symbolic value to the time travelers. This symbol can be seen on the Cave's metal door, on the Emerald Tablet, in The Stranger's papers, and in the Sic Mundus photo.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The Triquetra is shown on Thor's hammer, Mjölnir, in the 2011 film Thor. After OdinTemplate:Broken anchor utters to Mjölnir the words "Whosoever holds this hammer, if he be worthy, shall possess the power of Thor", the Triquetra vanishes. It represents Asgard, Midgard, and Utgard.<ref name="Mjolnir">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The Triquetra is also used on the logo of the video game developer Treyarch, one of the developers of the Call of Duty franchise.
