PETRUS CAMPER AND HIS ART WORKS DEPICTING THE RHINOCEROS
Petrus Camper (1722–1789), Dutch physician, artist
Camper writes in his lecture (delivered in Groningen in the Akademische Schouwburg der Ontleedkunde on 6 February 1772) that he saw the rhinoceros when she was in Leiden in 1748 (source 1801). He made several drawings (source 1802). Besides a painting in oil and a clay model, which were added to the collection of Gronovius (source 1804). Camper states that he had to buy them back at the auction of Gronovius in 1779 (actually 1778, source 1805).

Selected text in Dutch edition:
[p.139] En, Gyl. Hebt, genoegzaam alle gezien den Rhinoceros in den jaare 1741 door den Ed Heere Sichterman overgezonden, welke één enkelen hoorn hadt! Deeze is door J. Wandelaar by de Ontleedkundige Plaaten van den grooten Albinus gevoegd, en door gansch Europa omgevoerd, in Parys door den grooten Beesten-Schilder Oudry afgemaald, mede door anderen.
Van gelyken heb ik dien verscheidene maalen getekend, en in olie verwe geschilderd, ook in klaai gebootzeerd, in den jaare 1748. Welke twee laatste stukken lang geweest zyn in de verzaamelingvan den Heere Th. Gronovius, aan wiens vader ik dezelve als aan mynen grooten Begunstiger ten geschenk gegeeven hebbe (a).
(a) De familie heeft deeze naa het overlyden van dien Heer openlyk verkogt in den jaare 1779. En niet konnen goedvinden my dezelve te rug te geeven, zoo dat ik myn eigen werk, eerst geschonken, tegens geld verplicht wierdt in te koopen: offschoon ik voorgesteld hadde, dat de naagelaatene kinderen, die stukken myner jeugd tot een aandenken bewaaren zouden.
[p.147–148] De Kop van den Rhinoceros te Versailles was op het oog, en in schyn korter, om dat de plooi, die van boven den Kop langs den rand der onderkaak nederwaarts liep, zeer dik, en merkelyk dikker was dan in den Rhinoceros, dien ik in den jaare 1748 te Leiden afgetekend, en gebootzeerd.hebbe, . . . De Rhinoceros, die in Holland, en elders over 30 jaaren van veelen met my gezien wierdt, deedt hetzelfde.
[p.176] De Rhinoceros, welke ik te Leiden dikwerf gezien hebbe, at allerleie groentens, doch liefst geele wortels.
[p.176] De Rhinoceros schynt niet kwaadaartig. Die voormaals te Leiden was heb ik dikwerf uit de hand gevoerd, en den muil doen openen, door haar, want zy was een wyfje, een wortel voor te houden; als wanneer ik met vermaak het uit- en intrekken van haaren vinger der bovenlip zag.
English translation
[p.139] And, you have all seen the Rhinoceros sent over in 1741 by Mr Sichterman, which had a single horn! This one was added by J. Wandelaar to the anatomical plates of the great Albinus, and was transported throughout Europe, depicted in Paris by the great animal painter Oudry, as well as by others. Similarly, I have drawn it several times, painted it in oils, and also copied it in clay, in 1748. These last two pieces have long been in the collection of Mr. Th. Gronovius, to whose father I gave them as a gift as my great patron (a).
(a) The family openly sold these after the death of that gentleman in the year 1779. And they could not agree to give them back to me, so that I was obliged to buy my own work, which had first been donated, for money: even though I had suggested that my surviving children should keep these pieces of my youth as a memento.
[p.147–148] The head of the Rhinoceros at Versailles was visually and apparently shorter, because the fold that ran downwards from above the head along the edge of the lower jaw was very thick, and noticeably thicker than in the Rhinoceros that I drew and modelled in clay at Leiden in 1748. . . The Rhinoceros that many besides me saw in Holland and elsewhere through 30 years did the same.
[p.176] The Rhinoceros, which I have often seen in Leiden, ate all kinds of vegetables, but preferably yellow carrots.
[p.176] The rhinoceros doesn’t seem malicious. I often led the one that used to live in Leiden by hand and forced it to open its mouth by holding a carrot in front of her, as she was a female. I also enjoyed watching the finger of her upper lip extend and retract.

[p.69] Clara was also sketched by the young Petrus Camper (1722–1789), who was an accomplished and prolific artist besides his illustrious career as a scientist. Three drawings (black and white chalk on blue-grey paper) were first rediscovered among his papers and illustrated by Rookmaaker (1978a), showing an oblique front view, two views of the head, and a full side view (also figured in colour by Verhey 1992:31–34 and van der Ham 2022, figs. 15, 16, 17). An oil painting by Camper remains lost, after it was listed in the legacy of Laurentius Theodorus Gronovius (1730–1777): “no.51. Rhinoceros or two depictions of the animal painted in oil on a canvas in a black frame, 12 inches high and 10 inches wide [31 x 26 cm]” (Gronovius 1778:42). Two of these drawings include the date 1748 (figs. 05–27, 05–28), which is clearly repeated (“Rhinoceros, drawn and sculptured in the year 1748 in Leiden”) and linked with the history of Clara in Camper’s published lecture on the rhinoceros (Camper 1782:139,147). This date 1748 doesn’t fit Clara’s known history, neither do these drawings depict a full-grown rhinoceros. Camper’s side-view with a scale along all sides seems to indicate an animal with length of about 280 cm and height of 140 cm. This is similar to the size of a male calf in Basel Zoo which at an age of 3 years and 5 months measured 287 cm long and 131 cm high, with a horn length of 16 cm (Lang 1961:407). This shows that Clara’s assumed birth in the middle of 1738 and a proposed date of Camper’s drawings in late 1741 are the most likely scenario.

He was professor at Groningen at same time as Camper
A terracotta clay model was listed in the collection of G. van Doeveren (in The Netherlands), catalogue of 1785, with a date as “seen in Paris in 1749”. Camper and Van Doeveren were together in Paris in February 1753 when they recorded seeing the rhinoceros. Camper is known to have visited Paris from 15 June 1749 to 30 September 1749 – which is after the departure of Clara towards the south of France.
