Ahsan al-Taqasim fi Marifat al-Aqalim

Ahsan al-Taqasim fi Ma'rifat al-Aqalim (The Best Divisions for Knowledge of the Regions) is a foundational Arabic geographical work written in the late fourth century AH (tenth century CE) by the geographer and traveler al-Maqdisi al-Bishari (d. c. 380 AH / 990 CE) Kashf al-Zunun an Asami a…+1. It offers a comprehensive regional and socioeconomic survey of the Islamic world based predominantly on the author's extensive travels and firsthand observations Tarikh al-Adab al-Arabi l…+1.

Composition and Purpose

Al-Maqdisi resolved to compose the book around 375 AH (985 CE) in Shiraz when he was forty years old, and he produced a revised version in 378 AH Mujaz Dairat al-Maarif al…+1. In his introduction, he states that earlier scholars had pioneered various sciences and later writers had summarized or commented on their treatises, prompting him to pursue a discipline that had been largely neglected: providing a systematic, detailed account of the lands of Islam Ahsan al-Taqasim fi Marif….

Al-Maqdisi noted that his work was indispensable for travelers and of great utility to scholars, rulers, merchants, and literati Kashf al-Zunun an Asami a…+1. Beyond physical geography, the work covers deserts, seas, rivers, trade routes, commodities, agricultural yields, minerals, weights, measures, currencies, staple foods, drinks, dialects, physical characteristics of populations, religious sects, schools of law, customs, and holy sites Kashf al-Zunun an Asami a…+1.

Structure and Scope

Unlike classical Greco-Arabic traditions that divided the world into the seven mathematical climes, al-Maqdisi organized his work around fourteen administrative and cultural regions (aqalim) of the realm of Islam (mamlakat al-Islam), grouping them into seven Arab and seven non-Arab realms Mujaz Dairat al-Maarif al…+1:

• Arab Regions: The Arabian Peninsula, Iraq, al-Jazira (Aqur), al-Sham (Syria and Palestine), Egypt, the Maghrib, and the Syrian Desert (Badiyat al-Sham) Tarikh al-Adab al-Arabi l…+1.
• Non-Arab Regions: The East (al-Mashriq, encompassing Transoxiana and Khurasan), Daylam, al-Rihab (including Armenia and Azerbaijan), al-Jibal, Khuzistan, Fars, Kirman, and Sind Tarikh al-Adab al-Arabi l…+1.

In his treatment of each region, al-Maqdisi follows a three-part structure:

1. Topography and Settlement: The division of the territory into administrative districts (kuwar), subdistricts (nawahi), main cities (amsar), capitals (qasabat), and villages (rustaq) Tarikh al-Adab al-Arabi l…+1.
2. Human, Economic, and Cultural Geography: Descriptions of climate, agriculture, water sources, minerals, sacred sites, taxation (kharaj), markets, local currencies, weights and measures, dialects, customs, calendar systems, and the prevailing religious sects and legal schools Tarikh al-Adab al-Arabi l…+1.
3. Itineraries and Distances: Detailed routes connecting principal towns, with distances recorded in stages (marahil) and parasangs (farasikh) Kashf al-Zunun an Asami a…+1.

Al-Maqdisi accompanied his text with regional maps that used distinct colors to mark topographical features: red for routes, yellow for sand, green for salt seas, blue for freshwater rivers, and dusty grey for mountains Tarikh al-Adab al-Arabi l….

Methodology and Style

Al-Maqdisi categorized his sources into three levels of evidence:

1. Personal observation and empirical inspection during his journeys through almost all regions of the Islamic world (excepting outlying territories such as al-Andalus, Sijistan, and India) Tarikh al-Adab al-Arabi l…+1.
2. Reports from trustworthy informants and local residents concerning areas he could not personally reach, accepting what was corroborated by consensus and rejecting discrepancies Kashf al-Zunun an Asami a…+1.
3. Written source material from predecessors such as Abu Zayd al-Balkhi, al-Istakhri, and Ibn Hawqal Tarikh al-Adab al-Arabi l…+1.

When reporting unverified accounts, he prefaced them with phrases such as "they claimed" (za'amu) Majallat Lughat al-Arab a…. Stylistically, the book is composed in refined literary Arabic, employing rhymed prose (saj') in its introduction and interspersed with poetic citations Mujaz Dairat al-Maarif al…+1.
