Ibn Juljul

Abu Dawud Sulayman ibn Hassan Ibn Juljul was an Andalusian Arab physician and pharmacologist of perhaps Spanish extraction. He wrote an important book on the history of medicine. His works on pharmacology were frequently quoted by physicians in Al-Andalus during the 10th and 11th centuries. Some of his works were later studied by Albertus Magnus, like De secretis, under Latinized version of his name, Gilgil.
