Reference excerpt

The Sidi Yahya Mosque (Arabic: جامع سيدي يحيى; French: Mosquée Sidi Yahya), also known as the Mosque of Muhammad-n-Allah, is a mosque and madrasa of Timbuktu in Mali. The construction of the mosque began in 1400 under the leadership of Sheikh el-Mokhtar Hamalla of Timbuktu and was finished in 1440. The mosque was significantly rebuilt in 1939, resulting in its modern appearance. The mosque was named after its first imam, Sidi Yahya al-Tadelsi. It is associated with the historical community of scholars and students known today as the "University of Timbuktu", along with the mosques of Djinguereber and Sankore. The original mosque was a typical example of earthen Sudano-Sahelian architecture but also exhibited distinctive forms of plan and ornament. Parts of the modern mosque of Sidi Yahya were destroyed by Ansar Dine jihadists on 2 July 2012, following the Battle of Gao. These elements were later reconstructed under the direction of UNESCO team.

History The construction of the mosque of Sidi Yahya, sometimes written Sidi Yahia, began in 1400 by Sheikh El-Mokhtar Hamalla. The Sidi Yahya mosque is one of the oldest mosques in Timbuktu and holds special significance: when the Touareg under their leader Akil took control of Timbuktu in 1433, they gave the chieftaincy to Mohammed Naddi, a Senhaja from Chinguetti who commissioned the mosque. It took 40 years to complete. In 1441 Mohamed Naddah, the city-governor of Timbuktu, appointed his close friend Sidi Yahya al-Tadelsi, who was later venerated as a saint, as its first imam. Sidi Yayha's tomb is located in the mosque, which has meant it has historically attracted many visitors including Timbuktu's most renowned scholar, Ahmad Baba. The construction of Sidi Yahya as a madrassa allowed a massive expanse in the exchange of knowledge in Mali. Little is known about the mosque and its imams in the interval from 1468 to 1583, only that it was restored in 1569 by Qadi el-Aqib. The mosque was significantly rebuilt in 1939, resulting in its modern appearance.

In 1990, the government of Mali requested admission for the city of Timbuktu to UNESCO's list of World Heritage in Danger based on a threat of sand encroachment on historic buildings including the Sidi Yahya Mosque. While the community has kept Sidi Yahya better maintained than the two other main mosques in Timbuktu, years of erosion, wear on the foundation, and ineffective drainage threatened the structure. After adopting and implementing recommendations for protecting its architecture from the organization, Timbuktu was removed from the list in 2005.

Notable features & Architecture

Sidi Yahya is made in the Sudano-Sahelian Style and resembles its sister mosques in Timbuktu as well as the well known Great Mosque of Djenne. The earthen structure is made entirely of indigenous and natural materials. Every year because of rain and erosion, the community partakes in a festival in which the banco, or mud mixture, is reapplied to the building. The exterior of the building is studded with exposed beams of wood called torons which are used to climb to higher parts of the mosque to apply a new layer of mud. According to Prussin Labelle, the Sidi Yahya Mosque's architecture diverges slightly from traditional Islamic architecture's focus on cosmology. Instead of emphasis on divinity and heaven typically expressed through ornament and epigraphy, Sidi Yahya Mosque utilizes clay, mud, and rock to reiterate earthiness and connections to living and dead ancestors whose physical bodies remain buried within the mosque. Permanence and monumentality were the primary objectives in medieval African socio-political structures, and this permanence is thought to be reflected through the earth-based architectural styles used to construct the Sidi Yahya Mosque. The significance of earthworks and earth style architecture reflects the rules of ancestral significance in medieval Africa. Individuals who built the mosque along with other monuments were also grave-diggers and tomb-makers, further incorporating the sacred nature of the Earth and its ancestors into its style. Sidi Yahya closely resembles other famous mosques in Timbuktu, such as the Sankore and the Djinguereber mosques. However, key differences distinguish the Sidi Yahya mosque. The doors of the Sidi Yahya mosque are low and ornately designed, showing Moroccan influence from the time when the city was under Maghsharan Tuareg authority (c. 1400–1468). Architecturally, the building contains a covered prayer hall, internal courtyards, wooden doors, and arched openings. A single minaret with pointed arches rises above the mosque and main courtyard but does not reach the height of the two other large mosques in the city. The courtyard was later converted into a cemetery that is no longer in use. The imams of the mosque are buried in an underground area north of the building where evening and morning prayers are recited. It also contains lodgings for the mosque's guard. A smaller, external courtyard is used as reading space during the celebration of the birth of Muhammad. The roof of the mosque, like other buildings in Timbuktu, is supported by wood from the indigenous ronnier tree, covered with layers of mud to form the plaster-like exterior. Compared to other mosques of Timbuktu, this one benefits from greater care and maintenance.

Desecration

In the summer of 2012, members of Ansar Dine, a group tied to al-Qaeda, broke down the doors of the mosque, which according to legend were not to be opened until the end of time. The Jihadist's justification for the destruction of the city's shrines and mausoleums was that they contradicted the strict interpretation of Islam. Along with the mosque, the tombs embedded within its exterior surface were also desecrated. They claimed that the reverence for the site was idolatrous, as it was said that daily visits to the tomb of Imam Sidi Yahya would provide blessings to believers. The group later offered roughly $100 US dollars to repair the mosque, which was turned down by imam Alpha Abdoulahi. The following year, a suicide bomber from Ansar Dine destroyed windows and a door of the mosque and compromised the stability of its minaret. In 2016, the International Criminal Court found Ahmad al-Faqi al-Mahdi, a participant in the 2012 attacks on the monuments of Timbuktu, guilty of war crimes.

Worked examples

Example 1 — a first encounter with Sidi Yahya Mosque

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

In research
Sidi Yahya Mosque appears in engineering 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 Sidi Yahya Mosque 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
Sidi Yahya Mosque is common in secondary-school and first-year university syllabi. It links to neighbouring topics Archaeological sites in Mali, Buildings and structures completed in 1440, Buildings and structures in Timbuktu, so understanding it makes those chapters shorter.
In everyday life
Look for Sidi Yahya Mosque 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.
