"A most suitable book for any and all during the winter and holiday seasons is a reissue of a holiday present by the great mathematician and astronomer Johannes Kepler . . . The modern paperback includes not only Kepler's small masterpiece in English and Latin but also substantial descriptive and introductory pieces by Owen Gingerich of the Smithsonian Astrophysical Observatory and Harvard, and by Guillermo Bleichmar of St John's College in Santa Fe. Jacques Bromberg of the Tuxedo Park School provided the felicitous English translation, and snowflake drawings and a snowflake poem from 1990 are also included, the latter typographically displayed in snowflake form on the pages. Even the endnotes in this wonderful little book are interesting and educationally fun to read." -- Jay Pasachoff in The Key Reporter
