Erasistratus

Hey children!

As part of our e-twinning project, I’d like to talk to you about one of the greatest ancient Greek doctors and anatomists, called Erasistratus.

Erasistratus was born in Ioulida of Kea, in Kos, in Chios, or in Samos. He lived in Alexandria for some time  and he founded a school of anatomy there.

 

His achievements were many. He thought that the nerves moved a nervous spirit from the brain and he is credited with one of the first in-depth descriptions of the cerebrum and the cerebellum. He also examined the anatomy of the brain and he believed that we feel hungry because our stomach is empty.

 

Erasistratus was also sure that the spleen, the bile, and some other parts of the body were useless to animals. Some valves of the heart may have taken their name from him.

In conclusion, Erasistratus was a bright example of a person who tried to excel in anatomy and he achieved it! People like him should be role models for us!

Pedanius Dioscorides

Pedanius Dioscorides (40 – 90 AD) was a Greek doctor, pharmacologist, and botanist from Anazarbus of Cicilia. He was known for his five-volume work with the biggest influence on pharmacology until 1600 AD.

There are a lot of copies of his work even from the fifth century. He was the greatest pharmacologist of ancient times. His scientific contribution is as great as that of Theophrastos in botany. His manuscripts, which are very interesting, are at the libraries of Vienna, Naples, and Michigan.

Oenopides of Chios

Oenopides was born in Chios at around 500 BC. He lived in Athens where he became an astronomer and a mathematician.

Astronomy

Oenopides’s main accomplishment was the measurement of the angle between the plane of the celestial equator and the zodiac. He found that this angle was 24 degrees. Two centuries later Eratosthenes measured it better. In addition, Oenopides determined the duration of the Great Year to be about 59 years. This hepled to predict eclispes.

Geometry

He pointed out the difference between theorems and problems. The theorem serves for the development of a throery, while a problem is a theorem without development.

 

Furthermore, Oenopides said that for geometric constructions only the ruler (straighthedge) and the compass should be used.

Galenus was born in Pergamos in 129 AD and died in Rome in 199 AD. He was a very good doctor. He was the second best doctor after Hippocrates. he was a doctor of pathology, hygiene, surgery, and pharmacology.

Galenus invented a new medical practice which was used all around the Mediterranean Sea for a long time. He also found out that blood moves through arteries. Before this discovery, people believed that air moved through arteries!

Eudoxus of Cnidus

Eudoxus of Cnidus was born in 404 BC and died in 335 BC. He was a Greek astronomer, geometrist and mathematician. He went to the university of Tarentum and to the academy of Platon in Athens. For many years he lived in Egypt. He is one of the biggest mathematicians of Ancient Greece. He claimed that the world and the space were made from fire!

As you will see in the picture below, a crater on the moon has got its name from this great Ancient Greek scientist!

Eupalinos

Eupalinos was an architect from Megara. He became famous with his great work, the Eupalinos Tunnel in Samos. It was 1 kilometre long with sections of 175 x 1,75 m. Along the tunnel, Eupalinos built a pipeline that brought water to the city. This pipeline is today considered the most important technical work of that time.

Eupalinos was the most important architect of his time and so tyrant Polycrates asked him to build this tunnel, which was a very difficult job because they had to solve difficult geometric problems in order to build it in the correct place.
