Seventeenth-century botanical engravings flower again

A detail of the plate for Section 12, Tab. 11 of Robert Morison’s herbal, after cleaning.

In 1996, 291 copper plates, engraved with images of botanical specimens, were re-discovered (according to a later account) ‘in use as counterweights to a lift in the Radcliffe Science Library’,[1] one of the Bodleian Libraries of the University of Oxford.

They had been engraved by leading engravers of the time for two volumes of Robert Morison’s herbal, Plantarum historiae universalis Oxoniensis, published in 1680 and 1699. They had been wrapped in newspaper in the 1950s and stacked together but were found to be in very good condition. Twenty plates were expertly cleaned by the Conservation and Heritage Science team at the Bodleian Library, and re-housed in acid-free tissue with foam surrounds.

When The Old School Press proposed to print from these cleaned plates, the opportunity was taken to print these exceptional survivors once more on the rolling (or etching) press; twelve of the twenty were chosen as examples.

The Old School Press printed from the twelve chosen plates for a limited edition book. To limit any possible degradation of the plates, just forty prints were allowed to be taken from each, and the work of printing them was entrusted to Master Printer Jim Nottingham. To accompany the prints, Professor Stephen Harris, Druce Curator of the Oxford University Herbaria, prepared descriptions of the subject matter of each of the plates; Cambridge historian Scott Mandelbrote provided an introduction to Morison’s herbal and its history; and Jim Nottingham described the plates and the process for printing from them. The book, Plates for a Herbal, was published in May 2025.

Following the cleaning of twenty plates, the Bodleian Library initiated a project to examine in detail portions of both cleaned and uncleaned plates. During 2019 these were scanned in Optical 3D profilometry (O3D) in an Alicona machine at the Department of Engineering Science, at the University of Oxford. (See the earlier blogpost: https://blogs.bodleian.ox.ac.uk/theconveyor/copper-plates-in-the-bodleian-libraries/ )

After printing of only a few pulls from a few of the plates in 2024, the same portion of one cleaned plate was measured again using O3D. The results showed that this method requires much refinement before it is able to provide conclusive measurements of the wear on the copper plates. The initial profilometry had been able to show the complete contours of the plate surface, including the canyon created by the engraved lines, but the re-scanning following printing was unable to follow the contours into the depth of the lines due to wet ink trapped below the surface of the plate; at the bottom of the lines the Alicona machine was not able to take an accurate measurement due to the reflectivity of the new ink. Considering that the abrasion to plates during cleaning is one of the sources of wear, it was decided to forego further cleaning for the purposes of measurement. On inspection the plates did not appear to have suffered damage in undergoing the process for which, after all, they had originally been made.

The imaging of copper plates contributed to the results of a project begun at the Bodleian in 2021, a collaboration with the Factum Foundation, to make high-resolution images of low-relief surfaces. The ARCHiOx project has yielded further discoveries, the technological equivalents of finding historical printing surfaces in a lift shaft. (See the earlier blogpost: https://blogs.bodleian.ox.ac.uk/theconveyor/archiox-research-and-development-in-imaging/ )

The entire collection of the surviving plates for Morison’s herbal has now been returned to the Sherardian Library of Plant Taxonomy at the University of Oxford.

Unearthing a Hidden Melody

The secrets of engraved printing plates brought to light by innovative imaging

How do we see the past? Are there new ways to look at library objects? The display ‘Prints, Plates & Pixels’ which I had the pleasure to curate, open at the Weston Library from the 18th of May until the 18th of August 2024, shows the advancements made possible by the use of innovative imaging techniques and the collaboration of humanities and sciences to look at heritage objects. I began work in 2020 to examine the history and future of several hundred printing plates bequeathed by Richard Rawlinson in 1755 and held at the Bodleian Library. These objects were used to print images, often for book illustrations. While the printed image shows us the end result, the printing plates are the only living proof of the engraver’s work, showing us how deeply they engraved the lines and even when they changed their mind and made corrections!

Printing plates have shallow engraved or etched lines that only show their true detail when impressed in ink on paper. Inevitably, those shallow lines were flattened by repeated use and corrosion. My initial approach to studying the plates’ manufacture adopted traditional methods of viewing artworks in closeup, like digital photography, raking light and a magnifying glass. But the plates’ deterioration hampered my efforts.

However, I did not let that defeat me, and when in 2022, the ARCHiOx Project at the Bodleian Library was launched, I grabbed with both hands the chance to get involved. The project aimed to digitise Bodleian artefacts using prototype photographic and 3D scanning systems. The collaboration between Bodleian academics and Factum Foundation experts facilitated the exploration of the physical properties of Bodleian materials like Sanskrit manuscripts and the Gough Map of Britain, revealing previously unnoticed details and techniques. The opportunity to image some of the Rawlinson copper plates was transformative for my research on this collection of copper plates and led to new discoveries.

The most astounding was the identification of the engraved music on the reverse of a small portrait plate depicting Cardinal Julio Mazarin, included in the ‘Prints, Plates & Pixels’ display. I had noticed the notation during my initial survey, but only my collaboration with John Barret, Senior Photographer at the Bodleian, and Peter Ward Jones, former Curator at the Library, brought the music back to light.

Thanks to the ARCHiOx rendering, it emerged that the reverse of the copper plate is a fragment of Psalm 9 from the Cantus Primus part of William Child’s The First Set of Psalmes of III Voyces published in London by James Reave in 1639 and reissued by John Playford (1623–86) from the original plates in 1650 and 1656 as Choise Musick.

I was not expecting the formal portrait of the Cardinal to hide such treasure on its reverse. The discovery was truly momentous, but we must briefly consider the history of music printing in England to appreciate that. As I realised, the use of copper plates for music engraving was comparatively short-lived. Music engraved on copper first appeared in the country around 1612–13, but by the early 18th century, copper plates were replaced with softer pewter plates, which allowed faster production and had the considerable advantage of being cheaper than copper. This re-purposed item is now possibly the earliest surviving copper music plate in the world. In fact, many engraved plates were indeed sold for scrap metal once their commercial value was exhausted. Furthermore, during the World Wars of the 20th century, the need for scrap metal led to numerous publishers donating their stock of plates to support the war effort. Therefore, the preservation of pre-1900 music plates is absolutely remarkable.

This blog and my display, ‘Prints, Plates & Pixels’, offer a small glimpse into the exploration of historical printing plates through the lens of innovative imaging techniques and interdisciplinary collaboration. Through projects like ARCHiOx, the fusion of humanities and sciences enables profound discoveries, showing us even more from the rare survivals carefully kept in libraries and museums. Cutting-edge imaging technology can open new pathways for studying cultural heritage objects. Above all, innovative digitisation methods enhance accessibility and facilitate deeper exploration of artefacts.

About Richard Rawlinson:

The antiquary Richard Rawlinson (1690–1755) had a passion for preserving Britain’s heritage and the wealth to collect books, manuscripts, charters, prints, paintings, coins, and many other artworks that filled his London house to the brim. He left most of his collections to the University of Oxford, where they are preserved and studied today, constantly revealing more about their origins, use and significance. Among his collections were several manuscripts of Chaucer’s works, a medieval Anglo-Jewish bowl (now at the Ashmolean Museum)  and one of the earliest manuscript copies of Magna Carta [MS. Rawlinson C 641, fols. 21v-29 https://magnacarta.cmp.uea.ac.uk/read/magna_carta_copies/Magna_Carta_1215]. Rawlinson didn’t limit his collections to precious and unique artefacts. He also gathered scrap paper from cheesemongers and chandlers and used objects that were not prized by art connoisseurs. The 752 printing plates, dating from the early 17th to mid-18th centuries, are typical of this impulse since two-thirds of them are second-hand. They perfectly match Rawlinson’s interests: pictures of places, objects, and people that told the story of British history as he saw it. Rawlinson also created a sort of picture archive, commissioning engravers to depict unique objects in his own vast antiquarian collections either for book illustrations or to circulate privately among other antiquaries and collectors.

The display in the Weston Library opens 19 May 2024
