Gr. 3-5, younger for reading aloud. Introducing a person and a period largely unknown to children, this picture-book biography depicts the life of Eratosthenes, an ancient Greek who eventually became the head of the famous library in Alexandria. His most notable achievement was a remarkably ingenious method for measuring the earth's girth. After determining the angles of shadows in two cities and the distance between them, he used geometry to calculate the circumference of the earth. Illustrating the text with warmth and humor, Hawkes' acrylic paintings capture the period details of the setting and clarify the geometric concepts used in the measurement. The often dramatic compositions vary from page to page, while the sunlit reds, oranges, and yellows glow brightly against the cooler blues and greens. Even unnamed characters look like individuals, with their own concerns and personalities. Hawkes' attention to detail and his occasional visual humor will reward any child who studies the illustrations. Entertaining as well as instructional, the text presents the man, the story, the geometry, the geography, and the ancient world itself in simple prose. Lasky can be commended for making history so readable. And yet . . . is it history? Is it biography? Or is it fiction? In the introductory "Author's Note," Lasky explains that there are gaps in our knowledge of Eratosthenes and that "we cannot fill them in by making up facts, but we can try to responsibly imagine based on what we already know, which is what I've tried to do in this book." Unfortunately, the reader has no way of knowing what parts of the book are factual and what parts spring from Lasky's imagination. As a baby, was Eratosthenes really "curious and full of wonder"? Well, probably; most babies fit that description. Did he "crawl across the kitchen floor to follow the path of ants"? Maybe. Did he wonder "why there were beads of water on the cistern in the morning" and "why the stars stayed in the sky"? Or did the author "responsibly imagine" that part? How about the details of school life at the gymnasium in Cyrene? Was Eratosthenes "a real whiz in math" as a schoolboy? Or does Lasky imagine that he must have been a whiz as a child because of his later achievements in the field as an adult? A more careful wording of the text would separate knowledge from supposition, a fundamental principle of scholarship. When she speaks of Eratosthenes measuring the earth's circumference, Lasky says, "Perhaps he imagined the earth as a grapefruit." The word perhaps makes all the difference. If she had taken that approach from the beginning, this book would be outstanding. As fragmentary as the record may be, there's something special about real history, and readers can sense it. The old juvenile biographies with invented conversations fell out of favor for good reason. Readers count on nonfiction to deliver the truth: maybe not the whole truth, but nothing but the truth, within the limits of the author's knowledge. Eratosthenes sounds like a fascinating man, but it's difficult to sort out which parts of this book are historically accurate and which are not. The author's and illustrator's bibliographies of 25 books and articles reassure us that they know what is history and what is invention. But in calling the book a biography, the author has a responsibility to let readers know, as well. Otherwise, the book should be placed in the equally respectable category of historical fiction, which also requires enormous research but gives greater range for an author's imagination. Although flawed in its presentation of the main character, The Librarian Who Measured the Earth belongs in many libraries because it contains an entertaining introduction to the ancient world, a clear explanation of Eratosthenes' measurement of the earth, and remarkably vibrant illustrations.

Review by Publisher's Weekly Review
Newbery Honor author Lasky (Sugaring Time) deserves high marks for her attempt to present formal mathematical concepts in a picture-book format. The result, however, is a somewhat uneven amalgam of fable, history and science that struggles to find an appropriate age group. She tells the story of Eratosthenes, the ancient Greek librarian who figured out how to calculate the circumference of the earth by a sophisticated process involving sun and shadows. In an author's note, Lasky explains that since there is little extant documentation pertaining to Eratosthenes himself, her job as historian became to ``responsibly imagine based on what we already know.'' Unfortunately, the simplistic language and imagery she uses to describe his life contrast awkwardly with the somewhat daunting details of his mathematical innovations. Older readers who can understand abstract calculations might well be put off by such lines as ``More than two thousand years ago a very smart baby was born.'' Hawkes (see The Nose, reviewed above) handsomely illustrates both the mathematical and historical concepts with his signature touch of whimsy. His stunning acrylics add significant interest to the volume. Ages 6-10. (Sept.) (c) Copyright PWxyz, LLC. All rights reserved

Gr 2-5-This picture book covers 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.-Steven Engelfried, West Lynn Library, OR (c) Copyright 2010. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc.

Review by Horn Book Review
The imaginative prose and bright, lively illustrations of the ancient landscape tell the story of how Erathosthenes, the Greek mathematician and librarian, accurately measured the circumference of the earth more than two thousand years ago. His method for making the calculation, which involved insight and logistical finesse, is explained clearly in the text. Bib. From HORN BOOK 1994, (c) Copyright 2010.

Review by Kirkus Book Review
The story of Eratosthenes, a scholar of the third century b.c. Blending fact with informed conjecture, Lasky describes the education of a wellborn Greek boy, suggests questions he might have asked, and follows him from school in his native Cyrene (in what is now Libya) to further study in Athens and his post at the great library at Alexandria. Lasky highlights her subject's most notable qualities in a perky, lucid narrative. She depicts Eratosthenes's curiosity and orderly mind (he was an inveterate list maker) as the foundations of his greatest accomplishment: While writing a comprehensive geography, he estimated the circumference of the earth to within 200 miles of today's most precise measurements. With admirable clarity, Lasky explains exactly how he did it. Hawkes's pop-eyed characters burst with intelligence, while his lively full-bleed paintings include touches of humor amongst authentic details of the setting--in particular, some mischievous action on otherwise stately vases. An excellent contribution. Bibliographies for both Lasky and Hawkes; a note and an afterword place the librarian in histical context. (Nonfiction/Picture book. 5-10)
