Today, de Patra is known as one of the world's greatest thinkers and inventors as well as a renowned scientist for his exploration of basic hydrodynamics and human anatomy.
Carlo de Patra was born to Fernando de Patra and his wife Maria on the 15th of March, 1439. He was the oldest child and the only one to live past childhood out of five other siblings. His father was a Latin military officer who had served in the Achaean army, surviving the Roman Invasion of Achaea. He later went on to serve in the Roman military and was one of the few Latin officers who remained loyal to the Romans when the Latins later began the Latin Revolt. His mother was a native Greek merchant's daughter from Elis, further down the coast of Achaea. Because of this, de Patra had a comfortable early life and grew up loyal to the Roman Empire, unlike many other Latins who were hateful or at best ambivalent.
When Carlo de Patra was eleven, the Roman Empire went to war with the Ottoman Empire, which had claimed most of Greece. de Patra wanted to serve, but he was too young. However, when he was 17, he joined the military and participated in hunting down Turkish ghazis who still plagued Macedonia and Thrace, which were now free of Ottoman rule. His quick intelligence became apparent to his commanders, and de Patra was promotted to a low ranking officer position just like his father. de Patra remained in military service until 1462 when his enlistment expired.
While de Patra enjoyed his military experience, he had always wanted to attend an institution of higher learning and become a member of the Roman elite. Only the University of Constantinople offered such education, but the cost was high. de Patra's connections in the military gained him favor in the capital and his Greek grandfather eventually agreed to fund his education after considerable begging.
The University of Constantinople was entering into a new age of education and knowledge, much like the Empire was at the same time. At the University, de Patra excelled at many subjects like mathematics, chemistry, chemistry, and astronomy. His appetite for knowledge was well renowned by his peers and professors.
Following his graduation from the University of Constantinople, de Patra returned to Achaea. He began working as a scientist and physician, using his knowledge of common ailments to sustain his passions of research and invention. His inventions were and still are considered as far ahead of his time, and while many did not have the purpose to be utilized, they amazed his compatriots and even attracted attention in Constantinople, where de Patra was knighted for his work in science.
de Patra divided his research around the four basic elements of air, fire, water, and earth, focusing his inventions around basic principles associated with those elements. For fire, he focused on firearms and invented the first documented rifle in history as well as ways to refine gunpowder into a more powerful form. For air, he explored the mechanisms that made birds fly and how air reacted with solid objects, creating and testing the first parachute in Constantinople. For earth, he tested various ways of automatic motion and energy. And for water, he explored the motions of liquids and how they flowed, created the first diving suit in recorded history and also re-invented the Greek Fire thrower, which utilized the infamous liquid to burn enemies. To this day, de Patra is noted as the founding father of hydrodynamics.
