A mid-nineteenth century astronomical chart, outlining the necessary positions of sun, earth, and moon to create the greatest number of eclipses in a single year, from the 1866 edition of 'Smith's Illustrated Astronomy.' Assuming that on the first of January it is a new moon within 17 degrees of the ascending node, there would be seven eclipses in that calendar year, five of the sun and two of the moon. Asa Smith estimates that this happens not more often than once in a century. Smith's Illustrated Astronomy, Designed for the Use of the Public or Common Schools in the United States was a general astronomical textbook, first published in 1848 but improved and reprinted a number of times. The author, Asa Smith, described himself as 'Former Principal of Public School No. 12, City of New York,' and the text of the book is designed as a number of lessons, positing questions that teachers could address to their pupils, along with the answers, both simplified and in depth. Smith's knowledge of his subject was enthusiastic but often flawed, perpetuating numerous mistruths or historical misunderstandings, particularly in regards to the historical appreciation of astronomy. The most egregious of these occurs in Smith's very first lesson, which denies any ancient knowledge of the spherical shape of our planet, instead telling students that ancient peoples believed the world to be a flat disc supported by an elephant or a turtle. While true for some Huron, Hindu, and Chinese mythemes, it in no way compares to the beliefs of the classical astronomers upon which Smith purports to rely. For later editions, the numerous illustrations and diagrams were updated and improved by Prof. Newcomb from Harvard's Astronomical Department, though the lessons themselves remained relatively unchanged. Asa Smith (fl.1848) was a New York based educator, best known for his very popular Illustrated Astronomy, a textbook created for use by American Public Schools.
