Dissecting humans was taboo ...
That is utterly wrong
I was surprised to see you say that because I have so often read that it was. So I looked around and discovered that it depended where you were. Apparently Italy was one of the first regions to open up to dissections (some of the medical schools simply defied existing edicts) and the Paris medical school engendered a more liberal attitude. The rest of Europe, from what I can tell, followed more slowly. Some excerpts...
"Dissecting humans was forbidden in the Roman Empire, so people such as Galen used the bodies of apes. In both the Islamic and medieval Christian worlds, dissection was culturally taboo."
Aristotle did dissections, but apparently not of humans.
Galen wrote books on anatomy, but apparently used animals (Barbary apes) rather than humans for his dissections.
The Council of Tours (1163) spoke against human dissection in the sense of prohibiting the boiling of bones (which was actually a good thing since it reduced rot and disease, but people objected to this form of "desecration"), but the edict was interpreted more broadly than the original intention. However, it was possible for scholars to apply for an exception.
"Human dissection does not seem to have been practised regularly in the pagan, Jewish, Christian or Muslim cultures before the end of the 13th century..." (Katherine Park)
The Salerno medical school in southern Italy apparently defied the church edict and, in the early 13th century, performed human dissections.
Anglicus (13th c) discussed human anatomy, but I don't know if he based this on humans or animals.
The first anatomy text based on human dissection was written at the end of the 13th century by an Italian, the first manual on dissection was published in 1315.
There was apparently dissection of humans in northern Italy (I didn't know this, I had read otherwise). Leonardo's drawings of anatomy were not made public until after his death.
Northern Europe was more resistant.
In 1564, Andreas Vesalius (who published a milestone book of anatomy in 1543 and had studied in France where there was a more liberal attitude toward dissections) received a death sentence from the inquisition for doing a human dissection (detractors claimed the heart was still beating) but it is said the king intervened and supposedly sent him off on a pilgrammage to Jerusalem (others say he voluntarily left).
In 1565, physicians were given permission to dissect human cadavers at the London Royal College of Physicians.
