Naqus

Naqus 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 Naqus rather than just read about it. In short: The naqus (Arabic: ناقوس, romanized: nāqūs; Syriac: ܢܩܘܫܐ) is a percussion musical instrument, and under that name there are a set of traditions associated with Islamic-Christian relations. It can either be a bell or a wooden plank; in the latter form, it is similar to the semantron.

Key takeaways

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

Reference excerpt

The naqus (Arabic: ناقوس, romanized: nāqūs; Syriac: ܢܩܘܫܐ) is a percussion musical instrument, and under that name there are a set of traditions associated with Islamic-Christian relations. It can either be a bell or a wooden plank; in the latter form, it is similar to the semantron. The Arabic word nāqūs goes back to the Syriac naqosha (from naqash, "to strike") and reached the Aethiosemitic languages with the meaning "gong", "handbell". The show the two meanings of nagus...a billet of wood struck, and a bell or hand-bell. The instrument called a naqus is also referred to in the Bahá'í document Lawh-i-Naqus, "Tablet of the Bell". This "indicates a pierced wooden clapper-board which had a gong or bell-like function in making a noise when hit with a stick."

Tonewood

According to Islamic tradition, the companions of Muhammad were unsure of what the sign for the daily prayers (salāt) should be. Mohammad therefore decided between a fire, a bell, a Jewish horn (shofar) and the nāqūs for the muezzin's call to prayer (adhān). Apparently, in the early days of Fustat, the Muslims struck the nāqūs as an early-morning call to prayer. The sound of the nāqūs as a call to prayer was heard along with the crowing of the cocks. The name naqus was used among Christians too, who used the nāqūs since pre-Islamic times. Clattering wood (nāqūs) was mentioned by the poet Labīd (around 560 —661), who saw them in villages on the coast southwest of Qatar on the Arabian Peninsula. Archaeological excavations at a pre-Islamic Nestorian monastery on an island west of Abu Dhabi suggest that the church had an upper floor with a steeple, which probably contained a wooden nāqūs instead of a bell. In general, the nāqūs has often been at the center of cultural tensions between Christians in Arab areas. After Caliph Al-Walid I had the Byzantine cathedral of Damascus converted into the Umayyad Mosque around 705, al-Masʿūdī reported an incident that caused irritation. At the moment when the caliph mounted the minbar in the mosque to address the believers, a nāqus was heard. The proximity between the church and the mosque often seems to have caused noise pollution. The Islamic scholar Abu Yusuf (729/731-798) mentioned in his Kitāb al-Ḫarāğ (“Book on Property Tax”) the obligations that Christians had to observe under Islamic rule. This included not striking the nāqūs before or during Islamic prayer times. Elsewhere it is stated that the nāqūs should only be played softly or only within the church. These restrictions are also confirmed by the orthodox side, such as the patriarch Michael the Syrian (1126-1199) and the scholar Gregorius Bar-Hebraeus (c. 1225-1286). The naqus hitting loudly in public was considered a violation of the law. In return, Christian dignitaries were sometimes given permission to beat drums and play trumpets or other musical instruments at special religious ceremonies. The cauldron drum naqqara and long trumpets (buk) have been used to honor rulers since ancient times. The Jewish scholar Daniel al-Kumisi († 946) wrote that the use of the nāqūs was characteristic of the Christians of Jerusalem around 900. A mid-11th-century account of a town believed to be in Palestine mentions that the Christians ignored the existing laws and built a church higher than the local mosque. The church was then demolished, and the loud beating of the nāqūs also disturbed the Muslims.

Handbell

In addition to the tonewoods, the small bells that have come down to us from ancient Egyptian times and that Copts used in worship in Egypt are also called nāqūs. The oldest bells are known from the New Kingdom. The Christian Copts took up their forms again between the 3rd and 6th centuries. According to Hans Hickmann, the later use of bells in the Roman Catholic liturgy in Rome could have originated from this period. There are handle bells as half-shell handle bells without a clapper. Another type of nāqūs is shaped like a bedside lamp. The mushroom-shaped bell with a round base and a total height of 29 centimeters and a bell diameter of 22 centimeters is too heavy to hold in your hand. This nāqūs was used in the Catholic Church in Egypt in the mid-20th century, but not in the Greek Orthodox Church. Exclusively metal idiophones traditionally accompany liturgical chants in the Maronite Church in Lebanon. These include nāqūs made of two metal half-shells on a handle, which are struck with a metal stick and sound like triangles, as well as larger cymbals, paired cymbals and marawe (marawih, Sg. marwahah). The latter consist of a metal disc on a wooden handle about one meter long with small metal parts attached to the edge of the disc and are typologically related to rattle drums and sisters. The congregation receives the holy sacraments at the sound of nāqūs and marawe. The nāqūs, used by Christians, which was a wooden or metal striking plate, is mentioned in two tales in the Arabian Nights, in which it calls the faithful to prayer from the roof of the Chapel of Mary. A diminutive of nāqūs is nuqaisāt, by which the Berbers of the Maghreb mean finger cymbals.

Gebel naqus A geological feature was named for theme nagus based on a similarity of sound. The feature is a rocky mountain on the Red Sea coast in the south-west of the Sinai Peninsula (north-west of the coastal town of el-Tur and south-west of St Catherine's Monastery), called Gebel Naqus ('Bell Mountain'). The naming is based on the legend of a lost Christian monastery in the remote area near el-Tur. The legend says that the monastery disappeared without a trace so that nobody knows its location anymore, but from which the sound of prayer bells can be heard at certain hours. Captain Palmer, leader of an English expedition as part of the Royal Geographical Society to the Sinai Peninsula in 1868, reported Arabs who stated that the sound from the mountain could only be heard on Fridays and Saturdays and that it came from the beaten wooden planks of the sunken monastery. Ulrich Jasper Seetzen (1767–1811), who in the summer of 1810 (during the date harvest) stayed at el-Tur, discovered the mysterious ringing of bells on the slopes of Gebel Naqus and also found the physical explanation. Seetzen saw that from the hard-packed layer of sand covering the steep slopes of the hill, around midday, when the sun was particularly hot, loose sand began to slide down, making a sound that reminded him of the sound of Aeolian harps.

Worked examples

Example 1 — a first encounter with Naqus

Start with the simplest possible case. Write down what Naqus 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 Naqus 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 Naqus 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 Naqus

In research
Naqus 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 Naqus 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
Naqus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bells (percussion), Lithophones, so understanding it makes those chapters shorter.
In everyday life
Look for Naqus 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.
