Nunca imites ninguém. Que a tua produção seja como um novo fenômeno da natureza.

In one of his most famous drawings, Leonardo depicts a human fetus lying inside a dissected uterus. Leonardo is considered to be the very first in history to correctly depict the human fetus in its proper position within the womb. He was also the first to expertly draw the uterine artery and the vascular system of the cervix and vagina. Leonardo is credited with drawing the uterus with only one chamber, contradicting theories that the uterus was comprised of multiple chambers which many believed divided fetuses into separate compartments in the case of twins.
