The 13th century, even though politically overshadowed by the invasion of the Mongols and the end of the ‘Abbâsid caliphate, was also the golden age of Sufism. Known as Shaykh al-Akbar (the Greatest Shaykh), Muhyî al-Dîn Ibn al-‘Arabî was one of the most famous representatives of esoteric mysticism at the beginning of the 13th century. He was born in Murcia (city in Spain) in 1165 and at the age of eight he began his formal education and his parents moved to Seville. His work is complex, but it has an important philosophical aspect. He was one of the most prolific Sûfîs; 239 works are attributed to him. His most influential work, entitled Fusûs al-hikam (The Gems of the Wisdom of the Prophets), was inspired by a vision. In 1230, Prophet Muhammad appeared to Ibn al-‘Arabî in a dream, holding a book, and bade him to write down his teaching. This book relates the wisdom of twenty-seven Prophets. Many ideas inspired from Shî‘ism and Ismâ‘îlism are discernible in his works. Ibn al-‘Arabî was also inspired by al-Suhrawardî (d. 1191) who developed the Theosophy of Light establishing the Oriental Wisdom (Hikmat al-Ishrâq). One of its essential characteristics is that it makes philosophy and mystical experience inseparable. The disciples of al-Suhrawardî are designated as “Platonists” (Ashâb Aflatûn); Ibn al-‘Arabî was similarly surnamed “Son of Plato” (Ibn Aflatûn).
