IBN RUSHD IBN RUSHD, Abu 'l-Walid Muhammad b. Ahmad b. Muhammad b. Rushd, al-Hafid (the grandson), the 'Commentator of Aristotle', famous in the Mediaeval West under the name of Averroes, scholar of the Qur'anic sciences and the natural sciences (physics, medicine, biology, astronomy), theologian and philosopher. I. Life. He was born at Cordova in 520/1126 and died at Marrakush in 595/1198. The Arabic biographical sources are: Ibn al-Abbar, Takmila, BAH, vi, no. 853; Ibn Abi Usaybi'a, 'Uyun; al-Ansari, supplement to the dictionaries of Ibn Bashkuwal and of Ibn al-Abbar (notice published in the complete works of Renan, iii, 329); al-Dhahabi, Annales (ibid., 345); 'Abd al-Wahid al-Marrakushi, Mu'dhib. Ibn Rushd belonged to an important Andulusian family. His grandfather (d. 520/1126), a Maliki jurisconsult, had been qadi and imam of the Great Mosque of Cordova. His father was also a qadi. The biographers stress the excellent juridical education of the future Commentator; his teacher was al-Hafií Abu Muhammad ibn Rizq and he became very competent in the science of khilaf (controversies and contradictions in the legal sciences). He learned by heart the Muwatta'. Ibn al-Abbar mentions that he

Salé Puede calificarse a este segundo itinerario como una vía almohade por excelencia. Unía Marrakech con Rabat, con Tánger y Ceuta por un lado, y Fez y Mequínez por otro. La ciudad de Ksar el Kebir constituía en esa época un importante punto de convergencia de esta red. Saliendo de Marrakech en dirección Noroeste, el viajero deberá cruzar primero un puente de 27 ojos, inicialmente almorávide, reconstruido por los Almohades en el siglo XII. Más allá, Sidi Bou Othman , primera parada importante donde se realizaron importantes trabajos hidráulicos en la época almohade. Settat Arriba De ahí pasamos a Settat hoy ciudad muy bien acondicionada, de múltiples actividades económicas e industriales. Antaño era una parada indispensable para las caravanas a causa de los múltiples manantiales donde podían hacer sus reservas de agua. Allí se levantaba la alcazaba, de Moulay Ismaïl (s. XVII - principios s. XVIII). Settat, es desde hace tiempo un importante mercado de caballos árabes permaneciendo vivas las tradicionales paradas a caballo llamadas "Fantasia". La ruta de los almohades que unía Marrakech debía dirigirse a dos puertos muy activos en la época medieval, Tit (actual Mulay Abdallah al sur de El Jadida), y Azemmour, ambos lugares de peregrinación religiosa desde el siglo XII. En Tit, aún se pueden contemplar las ruinas de importantes fortificaciones almohades.

Rabat Casablanca Settat Mulay Abdallah ... Chellah This third itinerary could be classified as an Almohad journey par excellence Throughout this period the city of Ksar el Kebir was an important convergence point of this network. Heading north-eastwards from Marrakech, the traveller must first cross the 27-arched bridge which, although originally of Almoravid construction, was rebuilt by the Almohads in the twelfth century. Further on is Sidi Bou Othman the first important stop where an important hydraulic complex was built in the Almohad period. Settat Back From here we move on to the prosperous industrial town of Settat alcazaba al-qasbah , fortified enclosure) was constructed here by Moulay Ismaïl at the end of the seventeenth century and beginning of the eighteenth. Settat, with its traditional "Fantasia" stud-farms, has long been an important trading centre for Arab horses. The route of the Almohads uniting Marrakech would once have headed towards two ports, Tit (present-day Mulay Abdallah south of El Jadida) and Azemmour, both of which became religious pilgrimage sites from the twelfth century. The ruins of important Almohad fortifications can still be seen in Tit.

CHRONOLOGY – some selected dates in the development of sundials and solar astronomy Date Development 9000 BC to 8000 BC The Maya make astronomical inscriptions and constructions in Central America. A marked bone (possibly) indicating months and lunar phases in use in Ishango (Zaire) 4228 BC to 2773 BC The Egyptians institute a 365-day calendar. The start of the year, coinciding with the annual Nile floods, is linked to the rising of Sirius (the Dog Star) in line with the sun. 1500 BC to 1450 BC L-shaped sundials used in Egypt. 1450 BC to 1400 BC Stonehenge achieves the form known today. 600 BC to 590 BC Sundials are used in China and the Chinese text "Arithmetic classic of the gnomon and the circular paths of the heaven" contains a version of the Pythagorean theorem. 585 BC Thales of Miletus (Turkey) correctly predicts a solar eclipse. 520 BC to 510 BC Anaximander introduces the sundial to Greece (previously used in Mesopotamia, Egypt and China. He also produces a cylindrical (sic) model of the Earth. 500 BC to 490 BC The Pythagoreans (Greece) introduce a spherical model of the Earth.
