Hemophilia: Early Observations - Second Century For it was taught: If she circumcised her first child and he died [as a result of bleeding from the operation] and a second one died [similarly], she must not circumcise her third child.

Early Observations Tenth Century Islamic Surgeon Abul Qasim Al-Zahravi (Albucasis) 936 -1013 CE – Considered greatest surgeon of Middle Ages – Referred to a condition interpreted by scholars as hemophilia in his encyclopedic work on medicine and surgery, al-Tasrif Al-Tasrif Uman ‘Ajiza An Al-Taalif.
Early Observations Twelfth Century Physician and Talmudist Maimonides states in the Mishneh Torah 1 “If a woman had her first son circumcised and he died as a result of the circumcision, which enfeebled his strength, and she similarly had her second [son] circumcised and he died as a result of the circumcision - whether [the latter child] was from her first husband or her second husband - the third son may not be circumcised at the proper time [on the eighth day of life]…” 2 1.
