Jehan Cousin’s Livre de Pourtraiture (1608)

Adam Green - February 11, 2013 in anatomy, collections, geometry, Images, Images-16th, Images-17th, Images-Engraving-Line, Images-People, Images-Science, proportion, the body

Selected images from a 1608 edition of Livre de Pourtraiture by Jehan Cousin the Younger (ca. 1522–1595), son of of the famous painter and sculptor Jehan Cousin the Elder (ca. 1490-ca. 1560) who was often compared to his contemporary, Albrecht Dürer. Just before his death, Jehan the Elder published his noted work Livre de Perspective in 1560 in which he noted that his son would soon be publishing a companion entitled, Livre de Pourtraiture. While there have been some reports that an edition of Livre de Pourtraiture was fist printed in 1571 and again in 1589, no copies appear to exist. Instead, the most likely first printing of the work was 1595 in Paris by David Leclerc, with woodcuts engraved by Jean Leclerc, just after Jehan Cousin the Younger’s death. The book is one of the most famous on the subject of artistic anatomy and was printed again and again into the late 17th century. (All images from the U.S. National Library of Medicine).

Illustrations of Snowflakes (1863)

Adam Green - December 4, 2012 in collections, geometry, ice crystal, Images, Images-19th, Images-Science, snow, snowflakes, winter

The illustrative plates from Snowflakes: a Chapter from the Book of Nature (1863), a collection of poems, extracts, anecdotes and reflections on the theme of snow and the snowflake. According to the preface of the book, apart from the first few geometrical figures at the top of the first plate, which show the primary geo- metrical forms under which the snow-vapor crystalizes, all the other forms shown are “representations of individual crystals, actually observed and sketched with the aid of the microscope”. See the full book, including various poems and extracts from literature related to snow, here in our Texts collection. For some more snowflake related content have a look at Keith C. Heidorn’s article on Wilson Bentley, “The Snowflake Man of Vermont”. (All images taken from the book Snowflakes: a chapter from the Book of Nature (1863) which is housed at the Internet Archive, contributed by the California Digital Library).
