Abū al-Qāsim Khalaf ibn al-‘Abbās az-Zahrāwī (936–1013), (Arabic: أبو القاسم خلف بن العباس الزهراوي), popularly known as Al-Zahrawi (الزهراوي), Latinised as Abulcasis (from Arabic Abū al-Qāsim), was an Arab Muslim physician and surgeon who lived in Al-Andalus. He is considered the greatest medieval surgeon to have appeared from the Islamic World, and has been described as the father of surgery. His greatest contribution to medicine is the Kitab al-Tasrif, a thirty-volume encyclopedia of medical practices. His pioneering contributions to the field of surgical procedures and instruments had an enormous impact in the East and West well into the modern period, where some of his discoveries are still applied in medicine to this day.
He was the first physician to describe an ectopic pregnancy, and the first physician to identify the hereditary nature of haemophilia.
Al-Zahrawi was born in the city El-Zahra, six miles northwest of Córdoba, Andalusia. The nisba (attributive title), Al-Ansari, suggests origin from the Medinian tribe of Al-Ansar.
En su corcel cuando sale la luna
aparece el bravo zorro
al hombre de mal él sabrá castigar
marcando la senda del zorro
Zorro! su espada la matará
zorro! la Z le marcará
zorro!
