Muḥammad was a '' muwaqqit'' trained in clockmaking and astronomy who was commissioned by the Emir Nūr al-Dīn (1156–1174) to construct the water clock at the Jayrūn Gate by the entrance of the Umayyad Mosque in Damascus. Riḍwān also learned clockmaking and wrote a book in Arabic on his father's clock and the repairs and improvements he made to them, ''Risāla fī ʿamal al-sāʿāt wā-ʾstiʿmālihā''. This work he finished in 1203, after his father's death. Alt ...

13th-century Deaths
The 13th century was the century which lasted from January 1, 1201 ( MCCI) through December 31, 1300 ( MCCC) in accordance with the Julian calendar. The Mongol Empire was founded by Genghis Khan, which stretched from Eastern Asia to Eastern Europe. The conquests of Hulagu Khan and other Mongol invasions changed the course of the Muslim world, most notably the Siege of Baghdad (1258), the destruction of the House of Wisdom and the weakening of the Mamluks and Rums which, according to historians, caused the decline of the Islamic Golden Age. Other Muslim powers such as the Mali Empire and Delhi Sultanate conquered large parts of West Africa and the Indian subcontinent, while Buddhism witnessed a decline through the conquest led by Bakhtiyar Khilji. The Southern Song dynasty would begin the century as a prosperous kingdom but would eventually be invaded and annexed into the Yuan dynasty of the Mongols. The Kamakura Shogunate of Japan would be invaded by the Mongols. Goryeo res ...

12th-century Births
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by  2, although by other definitions 1 is the second natural number, following  0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is ...

People From Damascus
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...

Arabic Poetry
Arabic poetry ( ar, الشعر العربي ''ash-shi‘ru al-‘Arabīyyu'') is the earliest form of Arabic literature. Present knowledge of poetry in Arabic dates from the 6th century, but oral poetry is believed to predate that. Arabic poetry is categorized into two main types, rhymed or measured, and prose, with the former greatly preceding the latter. The rhymed poetry falls within fifteen different meters collected and explained by al-Farahidi in ''The Science of ‘ Arud''. Al-Akhfash, a student of al-Farahidi, later added one more meter to make them sixteen. The meters of the rhythmical poetry are known in Arabic as "seas" (''buḥūr''). The measuring unit of seas is known as "''taf‘īlah''," and every sea contains a certain number of taf'ilas which the poet has to observe in every verse (''bayt'') of the poem. The measuring procedure of a poem is very rigorous. Sometimes adding or removing a consonant or a vowel can shift the ''bayt'' from one meter to another. Also, in ...

Lute
A lute ( or ) is any plucked string instrument with a neck and a deep round back enclosing a hollow cavity, usually with a sound hole or opening in the body. It may be either fretted or unfretted. More specifically, the term "lute" can refer to an instrument from the family of European lutes. The term also refers generally to any string instrument having the strings running in a plane parallel to the sound table (in the Hornbostel–Sachs system). The strings are attached to pegs or posts at the end of the neck, which have some type of turning mechanism to enable the player to tighten the tension on the string or loosen the tension before playing (which respectively raise or lower the pitch of a string), so that each string is tuned to a specific pitch (or note). The lute is plucked or strummed with one hand while the other hand "frets" (presses down) the strings on the neck's fingerboard. By pressing the strings on different places of the fingerboard, the player can shor ...

Al-Adil I ( ar, العادل, in full al-Malik al-Adil Sayf ad-Din Abu-Bakr Ahmed ibn Najm ad-Din Ayyub, ar, الملك العادل سيف الدين أبو بكر بن أيوب,‎ "Ahmed, son of Najm ad-Din Ayyub, father of Bakr, the Just King, Sword of the Faith"; 1145 – 31 August 1218) was the fourth Sultan of Egypt and Syria, and brother of Saladin, who founded both the Sultanate of Egypt, and the Ayyubid dynasty. He was known to the Crusaders as Saphadin (derived from his ''laqab'' or honorific title Sayf ad-Din, meaning "Sword of Faith"), a name by which he is still known in the Western world. A gifted and effective administrator and organizer, Al-Adil provided crucial military and civilian support for the great campaigns of Saladin (an early example of a great minister of war). He was also a capable general and strategist in his own right, and was instrumental in the transformation of the decayed Fatimid Caliphate of Cairo into the Ayyubid Sultanate of Egypt. Fa ...

Vizier
A vizier (; ar, وزير, wazīr; fa, وزیر, vazīr), or wazir, is a high-ranking political advisor or minister in the near east. The Abbasid caliphs gave the title ''wazir'' to a minister formerly called '' katib'' (secretary), who was at first merely a helper but afterwards became the representative and successor of the ''dapir'' (official scribe or secretary) of the Sassanian kings. In modern usage, the term has been used for government ministers in much of the Middle East and beyond. Several alternative spellings are used in English, such as ''vizir'', ''wazir'', and ''vezir''. Etymology Vizier is suggested to be an Iranian word, from the Pahlavi root of ''vičir'', which originally had the meaning of a ''decree'', ''mandate'', and ''command'', but later as its use in Dinkard also suggests, came to mean ''judge'' or ''magistrate''. Arthur Jeffery considers the word to be a "good Iranian" word, as has a well-established root in Avestan language. The Pahlavi ''vi ...
