Templon

Templon is a chemistry 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 Templon rather than just read about it. In short: A templon (from Greek τέμπλον meaning "temple", plural templa) is a feature of Byzantine churches consisting of a barrier separating the nave from the sanctuary near the altar. The solid templon first appeared in Christian churches around the 5th century and is still found in many Eastern Christian churches.

Key takeaways

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

Reference excerpt

A templon (from Greek τέμπλον meaning "temple", plural templa) is a feature of Byzantine churches consisting of a barrier separating the nave from the sanctuary near the altar. The solid templon first appeared in Christian churches around the 5th century and is still found in many Eastern Christian churches. Initially it was a low barrier probably not much different from the altar rails of many Western churches. It eventually evolved into the modern iconostasis, still found in Orthodox churches. It is usually composed of carved wood or marble colonnettes supporting an architrave (a beam resting on top of columns). Three doors, a large central one and two smaller flanking ones, lead into the sanctuary. The templon did not originally obscure the view of the altar, but as time passed, icons were hung from the beams, curtains were placed in between the colonnettes, and the templon became more opaque. In modern Orthodox churches, it is common for the openings of the templa to be constructed specifically to contain icons.

Origins

The templon most likely has an independent origin from that of Latin chancel barriers. Classical stage architecture is one possible source. At certain times during Byzantine history, theater heavily influenced painting and sculpture. Architects then, influenced by stage backdrops dating back to Sophocles, consciously imitated the classical proskenion (Latin proscenium; the backdrop of a classical Greek stage), copying the multiple columns punctuated by a large door in the middle and two smaller doors to each side. The statues on top of the backdrop would thus be analogous to the icons of the saints looking down. The similarities, however, are probably only visual. Although classical drama was performed in Constantinople, the capital of the Byzantine Empire, during the 5th and 6th century when the first templa appear, when Christian liturgy was first being developed, the plays and their architecture had lost their importance and could not have influenced Christian ritual. A much more plausible theory is that the templon models, in both form and content, the decorative wall of the Torah screen in Jewish synagogues of the 2nd and 3rd centuries. These, too, had three main divisions: a central door leading to the altar, smaller flanking passages, and a distribution of parts similar to a templon. The Torah screen was probably not the direct prototype of the templon; it probably derives from the imitation of the Torah screen in the altar of a typical Syrian pagan temple. A direct comparison can also be made to the layout of the great Temple of Jerusalem. The most sacred and innermost portion, known as the Holy of Holies, was where the Ark of the Covenant was kept. This room was separated from the larger part of the main building's interior by a large curtain, the "veil of the temple". Only the High Priest was allowed to enter the Holy of Holies, and only once a year on Yom Kippur. The third part was the entrance court. This architectural tradition for the two main parts can be seen carried forward in Christian churches and is still most demonstratively present in Eastern Orthodox churches where the iconostatsis divides the altar, the Holy of Holies containing the consecrated Eucharist – the manifestation of the New Covenant, from the larger portion of the church accessible to the faithful. In Orthodox Christian tradition, with the exception of churches at women's monasteries, only men with good cause may enter the altar portion behind the iconostasis. Barriers called templons in Greek were also used on occasions when the Roman Emperors appeared in public, to segregate the Imperial retinue from the crowd.

Etymology Templon is a loan word in Greek, from the Latin templum, "temple"; how and why it came to have its present meaning is unclear. The most obvious explanation is that the form of the templon resembles a pagan temple. The steps up to the apse (semicircle where the altar is located) are analogous to the stereobate and stylobate of the temple (the floor of a temple). The colonnettes arranged in the π shape resemble the columns that surround all four sides of a temple, the architrave looks like the architrave on a temple, and the carved disks on the architrave are analogous to the metopes on the entablature. However, it has also been suggested that the name templon derives not from the pagan temples but from the Christian idea of the shrine where God was worshipped, or more specifically the Temple in Jerusalem. In almost all modern European languages, the word templon is a direct and late borrowing of the Greek architectural term, and it is rarely found outside the academic usage; besides the Greek templon, another direct descendant of the Latin templum, having the same architectural meaning, is the Romanian word tâmplă, "iconostasis".

Worked examples

Example 1 — a first encounter with Templon

Start with the simplest possible case. Write down what Templon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Templon 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 Templon 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 Templon

In research
Templon appears in chemistry 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 Templon 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
Templon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Architectural elements, Byzantine sacred architecture, Church architecture, so understanding it makes those chapters shorter.
In everyday life
Look for Templon 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.
