Since ancient times, the primary way to teach and learn anatomy have been to dissect human cadavers.

Students can watch a surgery on a screen from the classroom.

Many Renaissance-era universities had specially built operating rooms with galleries for the students to watch the action from.

These were called anatomical theaters.

At the center of the theater stood the operating table, where the surgeons performed.

Surrounding this table were several tiers of seating like in a Roman amphitheater.

From these advantageous positions, observers could get a good view of the proceedings.

Indeed, some surgeons seemed to revel in the showmanship aspect of their work.

These should be skilled men who have conducted several dissections.

Seating must be allotted in order of rank.

There must then be one Praefectus to keep an eye on everything and to put people in their places.

There must be guards to restrain the eager public as it enters.

Two reliable stewards should be chosen to make the necessary payments from the money that is collected.

In those days dissections were few and far between.

A full dissection sometimes stretched to two weeks.

Dissections were also carried out in the colder months to delay putrefaction.

The theater remains a matter of pride for the University and is still preserved.

Because of these exhibitions, the theater became a significant tourist attraction.

The theatre finally closed in 1821 when the department of anatomy was transferred to a new building.

The seats were carved and the walls were adorned with the signs of the Zodiac.

Public dissections were like grand shows, lasting three days and ending with a feast.

One of the finest anatomical theaters was in Bologna, Italy.

For three hundred years the theater was an object of reverence and admiration among visitors.

It was completely destroyed during the Second World War.
