Over 1500 years before Leonardo Da Vinci became the Renaissance Man, antiquity had its own in the form of Archimedes, one of the most famous Ancient Greeks. An engineer, mathematician, physicist, scientist and astronomer all rolled into one, Archimedes has been credited for making groundbreaking discoveries, some of which are undoubtedly fact and others that are almost certainly myth. Regardless, he's considered the first man to determine a way to measure an object's mass, and also the first man to realize that refracting the Sun's light could burn something, theorizing the existence of lasers over two millennia before they existed. People still use the design of the Archimedes screw in water pumps today, and modern scholars have tried to link him to the recently discovered Antikythera mechanism, an ancient "computer" of sorts that used mechanics to accurately chart astronomical data depending on the date it was set to.

Archimedes was a legend even among the Romans, who were expanding their empire during the great scientist's own lifetime. A Roman soldier has long been blamed for killing Archimedes after taking over Syracuse, but not before Archimedes reportedly helped the island's defenses with ingenious devices that burned Roman ships and even lifted some of them out of the water. The stories are probably apocryphal, but they speak to the man's reputation even among his contemporaries, and Cicero himself went to visit Archimedes' tomb.
