Eratosthenes de cyrene biography of mahatma: Eratosthenes was a Greek

Eratosthenes was the founder of scientific chronology; he endeavored to revise the dates of the chief literary and political events from the conquest of Troy. In number theory, he introduced the sieve of Eratosthenes, an efficient method of identifying prime numbers. He was a figure of influence in many fields. According to an entry in the Suda a 10th-century referencehis 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. Now part of modern-day Libya, Cyrene had been founded by the Greeks centuries earlier and became the capital of Pentapolis North Africaa country of five cities.

Like any young Greek, Eratosthenes would have studied in the local gymnasium, where he would have learned physical skills and social discourse as well as reading, writing, arithmetic, poetry, and music. Eratosthenes went to Athens to further his studies. There he was taught Stoicism by its founder, Zeno of Citium, in philosophical lectures on living a virtuous life.

He then studied under Ariston of Chios, who led a more cynical school of philosophy. He also studied under the head of the Platonic Academy, who was Arcesilaus of Pitane. His interest in Plato led him to write his very first work at a scholarly level, Platonikos, inquiring into the mathematical foundation of Plato's philosophies. Eratosthenes was a man of many perspectives and investigated the art of poetry under Callimachus.

He was a talented and imaginative poet. He wrote poems: one in hexameters called Hermes, illustrating the god's life history; and another, in elegiacs called Erigone, describing the suicide of the Athenian maiden Erigone daughter of Icarius. He wrote Chronographies, a text that scientifically depicted dates of importance, beginning with the Trojan War.

His father, Aglaus, encouraged him to study in Alexandria, which at that time was the greatest center of learning in North Africa. He was taught by the great grammar tutor, Callimachus, and began to learn philosophy from the likes of Ariston of the Stoic school and Arcesilaus the Academician. Having excelled at his studies, his abilities were noticed by King Ptolemy III Eurergetes, who commanded him to continue working in the city, replacing none other than Callimachus as the Chief Librarian at the Great Library.

He quickly became known as one of the most learned scholars in Alexandria, producing works on a wide variety of subjects. He effectively invented geography as a scientific discipline, producing a map which showed both parallels and meridians for the first time. He produced two books of mathematics, although these have been lost since ancient times.

From remarks made by some of his contemporaries, it seems that they touched on the nature of means and loci. Eventually, the only numbers remaining that had not been removed by one of these filters would themselves be primes.
