Cosmology in The Medieval Islamic World
See also: Astronomy in medieval IslamCosmology was studied extensively in the Muslim world during what is known as the Islamic Golden Age from the 7th to 15th centuries.
There are exactly seven verses in the Quran that specify that there are seven heavens. One verse says that each heaven or sky has its own order, possibly meaning laws of nature. Another verse says after mentioning the seven heavens "and similar earths".
In 850, al-Farghani wrote Kitab fi Jawani ("A compendium of the science of stars"). The book primarily gave a summary of Ptolemic cosmography. However, it also corrected Ptolemy's Almagest based on findings of earlier Iranian astronomers. Al-Farghani gave revised values for the obliquity of the ecliptic, the precessional movement of the apogees of the sun and the moon, and the circumference of the earth. The books were widely circulated through the Muslim world, and even translated into Latin.

Famous quotes containing the words medieval and/or world:
“Nothing in medieval dress distinguished the child from the adult. In the seventeenth century, however, the child, or at least the child of quality, whether noble or middle-class, ceased to be dressed like the grown-up. This is the essential point: henceforth he had an outfit reserved for his age group, which set him apart from the adults. These can be seen from the first glance at any of the numerous child portraits painted at the beginning of the seventeenth century.”
—Philippe Ariés (20th century)
“If melodrama is the quintessence of drama, farce is the quintessence of theatre. Melodrama is written. A moving image of the world is provided by a writer. Farce is acted. The writer’s contribution seems not only absorbed but translated.... One cannot imagine melodrama being improvised. The improvised drama was pre-eminently farce.”
—Eric Bentley (b. 1916)
