The Greeks were the earliest discoverers of much of the knowledge that went on to lay the foundations of scientific studies for thousands of years and one of the most important figures from that period is undoubtedly Eratosthenes, who was a mathematician, geographer as well as an astronomer of rare quality. Additionally he was also a music theorist which well and truly shows the sort of versatile knowledge and gifts that he possessed. Eratosthenes was responsible for bring to notice some of the most important discoveries in geography, astronomy and mathematics. Born in the Cyrene, the young lad was remarkably curious from an early age. He pursued higher education from Athens where he was taught by the best teachers of the day. Aristo of Chios and Arcesilaus in particular left a lasting impression on the budding philosopher. His reputation as a mathematician was affirmed when he measured the circumference of the earth using the shadows cast by the sun. He also made immense contribution to the field of geography by demarcating the five different climate zones existing in the earth. In fact the term geography was also coined by this eminent scientist. It can be unarguably said that this erudite scientist made discoveries that were way ahead of his time.

He was a figure of influence in many fields. According to an entry in the Suda (a 10th-century reference), his critics scorned him, calling him Beta (the second letter of the Greek alphabet) because he always came in second in all his endeavors. Nonetheless, his devotees nicknamed him Pentathlos after the Olympians who were well rounded competitors, for he had proven himself to be knowledgeable in every area of learning. Eratosthenes yearned to understand the complexities of the entire world.


Eratosthenes later rounded the result to a final value of 700 stadia per degree, which implies a circumference of 252,000 stadia, likely for reasons of calculation simplicity as the larger number is evenly divisible by 60. In 2012, Anthony Abreu Mora repeated Eratosthenes's calculation with more accurate data; the result was 40,074 km, which is 66 km different (0.16%) from the currently accepted polar circumference of the Earth.


Eratosthenes of Cyrene (/ɛrəˈtɒsθənz/; Greek: Ἐρατοσθένης ὁ Κυρηναῖος, IPA: [eratostʰénɛːs]; c. 276 BC – c. 195/194 BC) was a Greek Mathematician, geographer, poet, Astronomer, and music theorist. He was a man of learning, becoming the chief librarian at the Library of Alexandria. He invented the discipline of geography, including the terminology used today.


Eratosthenes was one of the most pre-eminent scholarly figures of his time, and produced works covering a vast area of knowledge before and during his time at the Library.
