Joseph Priestley’s very rare New Chart of History, a “masterpiece of visual economy” (Rosenberg and Grafton) and a landmark in the display of information. Offered here in extremely fresh condition, with vibrant original color.

The polymathic Joseph Priestly (1733-1804) was a British clergyman, theologian, scientist, political theorist, educator and prolific author with more than 150 works to his credit. Best known as a chemist, he is credited by many with the discovery of oxygen (Though Antoine Lavoisier also has a claim.) His fascination with electricity brought him into close friendship with Benjamin Franklin, who nurtured his career at key points and nominated him for membership in the Royal Society. A committed Whig, friend of America, and supporter of the French Revolution, his controversial views eventually made him unwelcome at home, and he spent the last decade of his life in self-exile in Pennsylvania.

Priestley became fascinated by “chronography,” the attempt to convey historical information in graphical form. Hitherto the field had been dominated by a straightforward tabular approach, with dates listed across one axis and regions or empires across the other, with the individual cells populated by discrete events. While information rich, such tables required much reading and prodigious feats of memory, while doing little to reveal the patterns underlying individual events.

Priestley’s first major chronographical production was his 1765 Chart of Biography. This charted the lifespans of some 2000 historical figures across three thousand years, grouped into six areas of endeavor: Historians Antiquarians and Lawyers Orators and Critics, Artists and Poets, Divines and Metaphysicians, and Statesmen and Warriors. It is impossible to find a good image of the Chart on line, but a “specimen” included as a plate in his Description of a Chart of Biography may be viewed here.

Priestley then turned his attention to historical events, and in this he was deeply influenced by Jefferys’ Chart of Universal History (1753), of which the only known example resides at the British Library. The significance of Jefferys’ chart was to combine the tabular format with a depiction of peoples and empires as continuous colored blocks rather than cells listing discrete events. While this lost detail, the great advantage was that one could take in the ebb and flow of empires at a glance: that of Alexander as a flat “pancake,” wide in extent but brief in duration; that of Rome as a huge colored mass (For an image of Jefferys’ chart, see pp. 114-115 of chapter 4 of Cartographies of Time, viewable here.) As Priestley wrote in a “Short Explanation, “This Chart is intended to exhibit a picture of history, or to give a clear view of the rise, progress, extent, and duration of every considerable empire or state.”

In his New Chart of History (1769), Priestley refined Jefferys’ approach by introducing a consistent time scale, whereas Jefferys’ version features a severely compressed scale for the epochs through 1000 AD. Priestly also introduced a variety of helpful visual conventions for clarifying the origins and terminations of countries and empires. As described in the “Explanation,”

“Each separate country or province is represented by a space bounded by line drawn parallel to the horizon. The termination of a space by a full [i.e., solid] line expresses its being annexed to some other country by conquest. If the termination be by a Broken line, the accession was not violent but peaceable. The name of the country, which make the acquisition, always appears in the continuation of the same space, or of a larger one in which it was absorbed. Dotted lines, in all cases, express uncertainty. The distant parts of very great empires are distinguished by colours.”

In another innovation, whereas Jefferys’ chart read top to bottom, Priestley rotated his so that time flows left to right. This had the great virtue of matching Western patterns of writing and reading, while also conveying the Enlightenment view of history as a narrative marked by forward progress. He dedicated the chart to his friend and supporter Benjamin Franklin, who must have appreciated both the honor and Priestley’s ingenuity.

In their Cartographies of Time, Rosenberg and Grafton describe Priestley’s charts as “masterpieces of visual economy” (117). To use a modern phrase, they enabled contemporary viewers to see “history at a glance.” In his Description of a New Chart of History, also published in 1769, Priestley wrote:

“If the reader carry his eye vertically, he will see the contemporary state of all the empires subsisting in the world, at any particular time. He may observe which were then rising, which were flourishing, and which were upon the decline. Casting his eye a little on each side of the vertical line, he will see what empires had lately gone off the stage, and which were about to come on.”

Priestley’s two charts were tremendously influential.

“Within very few years, variations on Priestley’s charts began to appear just about everywhere. When his own charts were not copied outright, they were adapted and interpreted, and, over the course of the nineteenth century, envisioning history in the form of a timeline became second nature.” (Rosenberg and Grafton, 130)

This influence reached well beyond chronography. For example William Playfair, who pioneered the presentation of economic data in graphical form, credited Priestley’s work as a valuable precursor.

A New Chart of History is extremely rare. Between ESTC and OCLC I find examples at only eight institutions worldwide, while the most recent example noted by Rare Book Hub on the antiquarian market was offered by Sotheby’s in 1963. I am aware of another impression that traded hands privately in this country a few years back. It is worth noting that in 1792 engraver Amos Doolittle of New Haven, Connecticut produced a new edition of the chart, which if anything is even more scarce than the London edition.

In all, a spectacular display piece and a significant rarity in the history of graphic design.
