Mansur ibn Ilyas

Mansur received most of his education from his family in Shiraz, who were also well established scholars, physicians, and active as jurists and poets.

It consists of seven sections: an introduction, five chapters covering the osseous, nervous, muscular, venous, and arterial systems, and an appendix on the formation of the fetus and compound organs, such as the heart.

A concluding section on compound organs, such as the heart and brain, and on the formation of the fetus, was illustrated with a diagram showing a pregnant woman.

Mansur's Anatomy is chiefly recognized for its inclusion of such colored anatomical illustrations, the first of its kind in the Arabic world.

Mansur ibn Ilyas' reasoning for the heart as the primary organ was that the semen is composed of air and strong heat, creating a substance called pneuma, which needs to be contained or it will decompose.

Kifāyah-i Mujāhidīyah كفايه مجاهديه (MS P 28, item 4) (The Sufficient [book] for Mujahid) While Mansur's Anatomy was not the first notation of the human body, it is considered to be the first color atlas ever created.
