No, Plato was not one of the teachers of Hippocrates. Plato was a Greek philosopher and mathematician who lived from 427 to 347 BCE. He founded the Academy in Athens, which was an influential school of philosophy. Plato's most famous student was Aristotle, who later became the teacher of Alexander the Great.

On the other hand, Hippocrates, also known as the "Father of Medicine," lived from around 460 to 370 BCE. He is associated with the Hippocratic Oath, which set ethical standards for physicians. Though Hippocrates lived during the same time period as Plato, there is no historical evidence to suggest that Plato was one of his teachers.
