[The Librarian Who Measured the Earth : The story of Eratosthenes, the Greek geographer and astronomer who accurately measured the circumference of the Earth around 200 B.C.] Impressionada com a pequena diferença encontrada, entre as medições atuais da Terra, com as que Eratóstenes experimentara há mais de dois mil anos atrás e, pela falta de dados históricos que pudessem trazer mais subsídios para a composição de sua biografia, a autora premia o público infantil, com uma bela narrativa sobre o matemático e bibliotecário-chefe da grande biblioteca de Alexandria, no Egito: (...) Eratóstenes foi um homem formidável e suas medições, se tivessem sido lidas por navegadores como Colombo, teriam ajudado a desvendar os limites da terra bem antes do que aconteceu. A autora se apaixonou por esse homem misterioso que deixou poucas pistas de como teria sido sua vida pessoal, mas deixou muitos livros e estudos. Os belos desenhos de Kevin Hawkes ajudam a reconstituir essa história gloriosa. Ricamente ilustrado, pelas fascinantes paisagens gregas, conta-nos a trajetória de um estudioso, que desde sua infância desenvolvera desejo investigativo e familiaridade ímpar com os números. Uma leitura prazerosa do início ao fim; diverte, educa, ensina e contribui significativamente para a Biblioteconomia. ==== https://pt.m.wikipedia.org/wiki/Eratóstenes ==== https://www.kathrynlasky.com/books/book/the-librarian-who-measured-the-earth The Librarian Who Measured the Earth by Kathryn Lasky: the life of Eratosthenes of Cyrene, a geographer who estimated the circumference of the Earth in around 200 B.C.. Though he was in fact a librarian, he is famous for his scientific accomplishments. Since little is known about his personal life, Lasky describes his early years in general terms. He liked to ask questions, loved learning at the gymnasium, and sailed off to Athens to further his studies. He became tutor to the son of King Ptolemy III of Egypt, and eventually became the head of Alexandria's magnificent library. Readers don't come to know the subject intimately, but they do get to know his times very well. The narrative is filled with fascinating details about his world. Hawkes's illustrations make a large contribution, as they contain authentic examples of the art, architecture, and social structure of ancient life. His paintings are rich and warm and filled with touches of humor, making the people, as well as their environment, come alive. The pictures combine with the text to give a clear explanation of how the man came to make his key discovery about the Earth's circumference. A fine combination of history, science, and biography.
