Nicomachus of Gerasa was an ancient Greek mathematician and philosopher who lived in the 1st century AD. He was born in the city of Gerasa, which is now modern-day Jordan. Nicomachus is best known for his mathematical treatise called the “Introduction to Arithmetic,” which was a comprehensive guide to number theory, arithmetic, and music theory. It is this text that we study in the Academy’s Classical Arithmetic course.
Nicomachus was heavily influenced by the Pythagorean school of thought, which was focused on mathematics and its connection to the natural world. He believed that mathematics was a way to understand the underlying order of the universe, and he aimed to make this knowledge accessible to all people. This is reflected in the title of his book, “Introduction to Arithmetic,” which was meant to serve as an entry point for anyone wishing to study mathematics.
In “Introduction to Arithmetic,” Nicomachus discussed various mathematical concepts, including prime numbers, perfect numbers, and the properties of the different types of numbers. In addition, he explored the relationship between mathematics and music, which was a key area of interest for Pythagoreans. He explained how musical notes could be understood as mathematical ratios and how musical harmony was a reflection of the harmony, or order, of the universe.
Nicomachus of Gerasa is the author of the “Introduction to Arithmetic” textbook that is studied in the Academy’s Classical Arithmetic course.
One of the most interesting aspects of Nicomachus’s work was his discussion of the “mathematical virtues.” He believed that the study of mathematics could help to develop important character traits, such as honesty, justice, and wisdom. He argued that mathematicians should strive to cultivate these virtues in their own lives, in order to better understand the truth about the world.
Despite its importance, Nicomachus’s “Introduction to Arithmetic” was not widely known in the ancient world. It was not until the Middle Ages that his work was rediscovered and became widely studied. During this time, it was widely used as a textbook in European universities and was considered one of the most important works on mathematics of the ancient world.
