BOHADDIN, or, more properly, DOHA-EDDYN, an eminent Arabian writer and statesman, better known in the East under the appellation of L3N-SJEDD..A.D. He was born at Mosul 1145 A.D. (539 A.n.), and early became eminent in the study of the Koran, as well as in jurisprudence. At the age of twenty-seven he obtained the place of lecturer at Baghdad, and, soon after, a professor's chair at Mosul. In 1187 lie made the pilgrimage to Mecca, and then proceeded to visit Jerusalem and Hebron. In passing through Damascus he was sent for by Saladin, who was then employed in the siege of Kancab. Bohaddin observed, as he himself mentions (Vita Saladini, c. v.), that the whole soul of the monarch was engrossed by the war which he was then waging against the enemies of the faith, and saw that the only mode of acquiring his favour was by urging him to its vigorous prosecution. With this view he composed a treatise on the Laws and Discipline of Sacred War; and this work, on his return, he presented to Saladin, who received it with peculiar favour. Bohaddin, from this time, remained constantly attached to the person of the sultan, and was employed in various important embassies and departments of civil government. lie was also appointed judge of the army, and judge of Jerusalem. After Saladin's death Bohaddin was active in securing the throne to his son, Melik-al-Dhaker, and was by that prince created cadi of Aleppo. He then founded a college in that city of which he himself was the principal professor. When Melik-al Dhaker died, his son Melik-al-Aziz was a minor, and Bohaddin obtained the principal sway in the regency. This gave him an opportunity of introducing learned men at court, and loading them with honours. As the prince, however, approached to manhood, Bohaddin, though he still retained his offices, found it expedient to retire from court. Even after he was unable to go to college, he continued to give lectures in his own house ; and he persevered in these learned labours till the age of ninety, when he died 1235 A.D. (633 A.n.) Bohaddin wrote on jurisprudence and Muslim divinity ; but his principal work is his Life of Saladin, which, with several other pieces connected with the same subject, was published by Schultens, at Leyden, in 1732, accompanied by a Latin translation, with notes and a geographical index. This work affords a favourable specimen of the historical compositions of the Arabs. It is written with some spirit, and yet is free from that inflation which so frequently disfigures Oriental composition. Whatever relates to Saladin breathes the highest tone of panegyric ; yet the enthusiasm with which everything concerning him is narrated, and the anecdotes which the author, from his personal knowledge, is able to communicate respecting that extraordinary character, give his work a great degree of interest.
