Historic Volvelle Puts the Cosmos at Your Fingertips

Volvelles, a type of rotating paper chart, have been used for centuries in books to explain complicated subjects, especially in the area of science.

A recent acquisition of ISU Special Collections and University Archives brings the cosmos to life.

“This moveable book which includes interactive elements like volvelles, is a text on cosmosgraphy which was an early term for the study of the universe – astronomy, geography, geology – everything between the heavens and the earth,” said Amy Bishop, rare books and manuscripts archivist. “The word volvelle originates from the Latin verb volvere, which means to roll or turn.”

The Italian book, "Epitome Cosmografica," was written by Vincenzo Coronelli and published in 1693. Coronelli was the official cosmographer of the city of Venice, Italy, at the time. He founded the first geographical society and became renowned for his celestial and terrestrial globes.

Epitome Cosmografica includes three sections: astronomy and cardinal directions; geography and natural phenomena; and globes, armillaries (spherical frameworks of longitude and latitude), and astrolabes (instruments to make astronomical and navigational calculations).

Plates used in the volume detail the progression of scientific advancements at the time including placing the Sun at the center of the solar system rather than the Earth. The book’s circular pieces are layered together and rotate around a central pin to reveal different information when turned various ways.

This distinctive volume was acquired with funds provided by donors to the University Library.

Bishop is interested in expanding Iowa State’s collection of movable books featuring volvelles, flaps, and pop-up elements, especially in the areas of science.

“Pieces such as this are helpful for scholars to see the cultural heritage of the science they’re studying and there’s impressive design and engineering elements to be considered in the construction of these manuscripts,” Bishop said. “I work with a lot with College of Design students in an array of majors, and these volumes show students what’s possible and inspire their own unique creations.”
