Editorial Reviews

KLIATT
An impressive, thorough addition to the middle school reference shelf, this summary of time designation and calculations answers the younger YAs' need for data on the beginnings of number systems, clocks, and calendars. The narrative pairs beautifully with stylized drawings of seasonal record keeping, the study of constellations, notations on the agricultural year, and the adoption of mechanical clocks. The authors cover global contributions to time keeping along with pictures of archival materials, holiday celebrations, and the ongoing human appreciation of the dependable cycles in nature. Significant names—Augustus Caesar, Pope Gregory, Sosigenes, and Dionysius Exiguus—indicate the impact of human control on methods of recording the passage of time. Commentary on the importance of calendars to religion is nonjudgmental. This work would serve the classroom teacher or librarian for a read-aloud adjunct to science texts or as a recommendation to the intellectually curious student. KLIATT Codes: J—Recommended for junior high school students. 1999, HarperTrophy, 48p. illus. index., Ages 12 to 15.
