The last two volumes of the Catalogue of the Cotsen Children’s Library, a comprehensive index, have just been published, bringing this huge project to completion. This post will offer a survey of the pictures of children appearing in the preliminary pages of the eight volumes that illustrate the subject of teachers and pupils interacting in traditional and innovative classrooms.The frontispiece to vol. 1 of the pre-1800 imprints is a portrait of Margaret Bryan, a pioneering science educator for girls that appeared in her first such work, A Compendious System of Astronomy, in a Course of Familiar Lectures of 1797 (Cotsen 31780). The two young ladies are her daughters; this plate was engraved by William Nutter after a painting by Samuel Shelley. Bryan represents just one of many women writers for children whose works are described in the catalogue; she was unusual for attaching a likeness of herself in her book. Mothers are frequently portrayed in their role as their children’s first teacher. It is no surprise that the allegorical figures of instruction and grammar are also represented as females, as in this mezzotint print ca. 1720 engraved by J. Jacques Haid after a painting by Hans Rottenhammer (Cotsen 38458) used as the frontispiece to the second volume of the index. The rather masculine-featured woman solemnly shows a toddler a tablet of the letters of the alphabet, the first step towards literacy. The child seems engaged by the task he is being set.Children like the play the part of teacher. This little girl is too old for the alphabet blocks scattered on the floor, so perhaps she is preparing the doll in her lap for a lesson. This detail from a drawing in ink and gouache (Cotsen 18123) by British artist Helen Jacobs, possibly for Alice’s Alphabet.Jessie Wilcox Smith’s picture of a studious girl biting the end of her pencil from Carolyn Wells’s The Seven Ages of Childhood from 1902 (Cotsen 18997) was chosen as the frontispiece for the second volume of twentieth century imprints. We take for granted girls’ right to an education, but some illustrations in early modern school books are reminders that they were not welcome until comparatively recently, and if they were present, very much in the minority. The title page vignettes for the pre-1800 volumes, The Parents’ Best Gift: or, The School of Learning [between 1748 and 1776} (Cotsen 26265) and Edward Coote’s The English School-Master (1658) (Cotsen 34054).Documenting the history of visual learning was a subject very close to the donor Mr. Cotsen’s heart, so illustrations of learning spaces full of pictures were essential. If they really represent actual classrooms used for instruction, they were simply spectacular. This spacious room shown in the frontispiece to the second volume of the pre-1800 imprints comes from the picture dictionary Primitiva latinoe linguoe circa 1736 (Cotsen 1088).This one, which opens out into a formal garden,makes an extensive gallery and a collection of scientific instruments available to the pupils. It was taken from Sechzig eroefnete Wekstaette der gemeinnuezigstem kuenste und Handwerk fuer junge Leute of 1789 (Cotsen 91643). The illustration by Adrien-Emmanuel Marie of the father indulgently watching his son intent on assembling a jigsaw puzzle serving as the frontispiece to the L-Z volume of nineteenth-century imprints brings us back into the home, an important site for learning, especially in families that could afford novel aides to education. This came from Jules Jouy’s Le chanson de joujoux of 1892 (Cotsen 3253), as does the final picture in the post, a critical reminder that all work and no play makes Jacques a dull boy…Special thanks to Stephen Ferguson, Associate University Librarian for External Engagement and designer Mark Argetsinger, who together made Mr. Cotsen’s dream of a fabulously illustrated multi-volume catalogue of his collection a reality. As all of us who worked on this massive project can testify, along with the great children’s poet Kornei Chukovskii, “Ach! It’s no light task to pull a hippo from the marsh!” Thanks for persevering!
