Summary and Keywords

Ancient Greek and Roman scientific and technical works, especially in the exact sciences, were much more commonly illustrated than texts in other genres. The images in those texts ranged from the relatively abstract diagrams in mathematical, astronomical, and harmonic texts to the more pictorial images of botanical, medical, and surveying texts. For the most part, the images that survive are found in medieval manuscript copies. Although there are often striking variations from one manuscript to another, and the parchment or paper codex offers very different possibilities for illustrations than the papyrus rolls on which the ancient texts would originally have been composed, the texts themselves often offer clues about the author’s intentions for the images that accompanied the text.

Keywords: ancient engineering, ancient mechanics, ancient medicine, ancient science, ancient surveying, ancient technology, manuscript illustrations, technical drawing

Illustrations ranging from schematic diagrams to veristic pictorial images are found in surviving copies of many Greek and Roman works on mechanics, harmonics, surveying, medicine, zoology, pharmacology, and other technical subjects.1 However, very few ancient illustrated texts of any kind, including technical texts, survive; the vast majority of illustrations are found in medieval copies of the texts. Kurt Weitzmann influentially posited a transition from “papyrus-style” ink illustrations, set “integrally” into columns of text, to a more “pictorial” style of painted illustrations in codices, and argued that during this transition illustrations became increasingly independent from the text.2 Further studies have complicated and expanded upon Weitzmann’s model.3 Nevertheless, images in surviving papyrus rolls are indeed often inserted into columnar blocks of text, while those in a codex more often occupy an entire page facing or near their accompanying text or are relegated to the margins of the page.

The codex is certainly a better host for painted images than the papyrus roll, since the pigments are not subject to the same mechanical stress on a page that remains flat as on a papyrus intended to be rolled and unrolled.4 Surviving technical illustrations in codices are outlined in ink and often colored with paint or ink wash. The precision with which they are drawn, depending on whether the illustrator availed himself of tools like compass and straightedge, varies widely even between copies of the same text.5 Three-dimensional structures are generally represented using a simple orthographic projection; isometric and oblique projections did not become standard until the 16th century. Images may be linked to their associated text via letter labels; the use and density of labels varies quite widely between authors. Though the manuscripts of ancient technical works were created considerably later than the texts they transmit, in most cases they are the sole surviving evidence for the images those texts contain. Letter labels and other textual references can help to regulate the transmission of the images, but some variation occurs in any case.

The few surviving illustrated papyri of technical texts are predominantly mathematical and astronomical works (see diagrams). The illustrated astronomical papyri most commonly feature tools used in the astronomer or astrologer’s work like parapēgmata and other tables, such as the 3rd-century bce Hibeh weather parapēgma (P. Hib. i 27).6 Other tables, sometimes drawn in both red and black, were used in the calculation of horoscopes (e.g., P. Oxy. Astron. 4148–4235).7 Zodiacal diagrams and other visual elements on the surviving inscriptional parapēgmata and parapegmatic molds suggest that comparable images might sometimes have accompanied the verbal and numerical lists and tables known from the surviving papyrus parapēgmata.8 The so-called Eudoxus papyrus (P. Par. 1), a quite early example of an illustrated papyrus, probably dates to the 2nd century bce.9 This papyrus in fact contains not a text of Eudoxus but an astronomical miscellany citing him among others, so-called from an iambic acrostic on the verso which spells out his name. Its line drawings, in red and black ink, depict the zodiacal constellations, as well as interactions between cosmic bodies such as eclipses.


The surviving manuscripts of the Roman surveyors or agrimensores (see gromatici) include a wealth of illustrations, ranging from maplike drawings of settlements to diagrams of the areas a surveyor must learn to measure. Diagram-style illustrations are a particular characteristic of the text Expositio et ratio omnium formarum (or Expositio et ratio omnium mensurarum) by the surveyor Balbus, who probably wrote in the 2nd century ce.10 Balbus’s text is explicitly structured after Euclid’s Elements, plainly intended to assimilate the surveyor’s work to geometry, though his diagrams do not include letter labels.11

The maplike illustrations found in other texts from the Corpus Agrimensorum, included notably in the Codex Wolfenbüttel Arcerianus A (Cod. Guelf. 36.23 Aug. 2°, which probably dates to the 6th century ce) are quite different (see figure 1).12

Though the settlements depicted are overlaid with the rectilinear grid of centuriae, the scenes are drawn from an elevated perspective; feature different kinds of buildings; and are often adjacent to rivers, seas, or mountains. However, while the scenes in the surviving manuscripts are drawn in a veristic style that suggests real rather than idealized locations, they typically show generic rather than particular settlements, and it is doubtful that they derive from actual maps.13

A tradition of actual maps executed in bronze and marble formed part of the surveyor’s work long before the surviving manuscripts of their texts. Several of the agrimensorial texts mention bronze cadastral maps of settlements; though these records have been almost completely lost, a fragment of a bronze plaque depicting part of the territory of the Roman settlement at Lacimurga has been discovered in Spain.14 The most spectacular surviving evidence for agrimensorial maps is the immense marble map at Orange, which includes a pictorial representation of the settlement’s centuriated land, each centuria inscribed with information about ownership and land use, as well as topographical features like rivers and roads (see centuriation).15

Beyond the extant cadastral maps, very little evidence survives for what ancient maps looked like and how they were used. Indeed, Pietro Janni and Kai Brodersen have argued that space was conceived by Romans through one-dimensional lines, as ancient itineraries and periploi suggest, rather than two-dimensional visual maps; this argument has been effectively criticized by Richard Talbert.16 Whether or not travellers used visual maps, they were present at Rome; the most notable survivor is the Forma Urbis Romae, inscribed on a wall in the Forum of Vespasian in the early 3rd century ce.17

While ancient geographical works make frequent reference to maps, the texts themselves (like those of the surveyors) seem usually not to have included maps (see geography). The so-called Artemidorus papyrus represents an unusual opportunity to observe what ancient maps might have looked like, as it features a map of at least part of Spain peppered with symbols that may represent settlements, monuments, watercourses, and so forth.18 The map is evidently correlated with the textual description of Spain on the papyrus. Though many of the surviving medieval manuscripts of Ptolemy’s Geographica include detailed maps, in the text itself Ptolemy recommends transmitting geographical information in tabular rather than graphical form, because copying maps introduces errors.19 As Berggren and Jones note, there is no guarantee that maps originally accompanied the text of the Geographica at all.20 Much of the text is devoted to tables of latitudes and longitudes, along with instructions for reconstituting the tabular data into a planar or spherical map.


Texts on mechanics very often make reference to diagrams, and the surviving manuscripts include a varied stock of illustrations ranging from schematic diagrams of individual components to depictions of completed machines in action.21 The tradition of theoretical mechanics, along with its distinctive images, survives best in Greek in the Peripatetic Mechanica, as Hero’s Mechanica survives more completely in its Arabic and Persian traditions.22

Hero of Alexandria’s works on pneumatics and automaton-making are the sole surviving Greek texts on those subjects, though Philo’s earlier work survives to some extent in Arabic and Latin, with a distinctive tradition of illustration.23 Pneumatic devices and automata were highly decorative as well as mechanically complex; the illustrations usually show the internal components clearly, adumbrating the exterior decorations in a way that does not obscure the working components.

Hero’s Dioptra, a work on surveying, includes illustrations of the eponymous sighting instrument as well as diagrams of the surveying problems it is used to solve; the end of the text describes as well the construction of an odometer, whose gearing system is depicted in surviving manuscripts as early as the 10th-century Mynas codex (Par. suppl. gr. 607).

The same codex includes Hero’s Belopoeica and Cheiroballistra, two texts on ballistic machinery which judging by the population of surviving manuscripts were extensively illustrated and frequently copied (though the Cheiroballistra survives only partially in this tradition) (see artillery). The Cheiroballistra focuses on a single type of small catapult and its manuscript tradition features detailed schematics of individual components, whereas the Belopoeica gives a history of different types of catapults and depicts their complete forms as well as selected components. Also included in this codex are the works on siege engines by Athenaeus Mechanicus and Apollodorus of Damascus, probably written in the 1st century bce and the 1st century ce, respectively. The illustrations of both those works show the devices they describe as complete machines, often engaged in military action.24 The same works are also contained in the 11th-century Paris Grec 2442, an opportunity to compare two instantiations of these texts’ transmission histories.


Ancient manuals of military tactics yielded a long-lived tradition of diagrams depicting soldiers in formations and their manoeuvres. The earliest surviving text to include these images seems to be Asclepiodotus’s Tactica. Not much is known about Asclepiodotus as an author, though it has been supposed that he may be identified with Posidonius’s student of that name mentioned by Seneca (and the Tactica itself even ascribed to Posidonius). Asclepiodotus’s work survives in a 10th- or 11th-century manuscript in the Biblioteca Medicea Laurenziana (Cod. Laurentianus Plut. 55.4), from which the later manuscripts descend. Asclepiodotus’s diagrams of military formations adapt the mathematicians’ letter-labeling techniques to soldiers in formation. He labels each rank, file, or even each individual soldier with its own letter, facilitating his verbal representation of manoeuvres like ranks exchanging positions or entire battalions performing quarter-turns. Aelian composed his own Tactica in the 1st or 2nd century ce, and while his text bears a very close resemblance to that of Asclepiodotus, his diagrams are quite different (see, for example, the 11th-century Codex Parisinus gr. 2442, where they accompany the works on military engineering described above). Rather than representing soldiers by letters, Aelian’s diagrams use symbols to indicate infantry, file-leaders, and cavalry. Although the resulting diagrams are not connected to the verbal text with Asclepiodotus’s dense references to individual letter labels, they are easier to parse and orient, which perhaps explains why later Byzantine tactical compendia seem to have adopted Aelian’s diagrammatic strategy rather than Asclepiodotus’s.


The surviving evidence for architectural drawings from ancient Greece and Rome is quite sparse, surprisingly so given the well-known centrality of visual representations to western European architecture from at least the 15th century onwards.25 Vitruvius’s De architectura, the sole complete treatise on architecture surviving from antiquity, refers to included illustrations. However, his manuscript tradition omits these, though modern editions and translations often reproduce images from Renaissance architectural treatises derived from Vitruvius.26

Heisel catalogues much of the surviving Greek, Roman, Mesopotamian, and Egyptian evidence for architectural drawings, both material evidence and textual references.27 The surviving Greek materials, largely engravings of columns, roof inclinations, and decorative elements, are almost all done at full scale on stones later incorporated into different parts of the building and oriented so the engravings would not be seen. Such large engravings are obviously a very different product from scaled-down plans of whole building installations; Greek and Roman architects might have used such plans but they have hardly survived. A rare exception is the “Pytheos sketch” from the temple of Athena at Priene, a scaled-down plan of the temple as a whole.28

Though very little direct evidence for Greek or Roman architectural illustrations survives, Vitruvius’s description of the architect’s drafting practices offers some indications as to what forms they, and perhaps other types of technical illustration, might have taken. He stipulates three varieties of drawing: ichnographia, orthographia, and scaenographia.29 The first of these, for which Vitruvius prescribes the use of compass and ruler, refers to a ground-level architectural plan. The second is an elevation of the side of a structure, with some added color. The third depicts the face and sides of the building, with all lines converging on the center of a circle; Vitruvius later relates this perspectival system to the illusion of depth in theatrical paintings (see Agatharchus, painter).30 Scaenographia is discussed as well in a passage attributed to Geminus and later integrated into Hero’s Definitiones as a branch of optics addressing optical illusions of perspective; it furnishes techniques for proportioning a building in such a way that it will appear symmetrical to a viewer on the ground.31

Pharmacology and Medicine

Dioscorides’s pharmacological work De materia medica, written in the 1st century ce, was possibly not originally illustrated, but its manuscript tradition includes a broad range of detailed illustrations.32 The best-known of these manuscripts is the sumptuously illustrated 6th-century “Vienna” Dioscorides codex which includes lavish, veristic full-page painted portraits of the plants and animals of Dioscorides’s De materia medica, as well as the birds of Dionysus of Philadelphia’s Ornithiaca and the snakes of Nicander’s Theriaca.33

Human figures are not commonly illustrated in the surviving anatomical and medical texts. A rare exception is Apollonius of Citium’s commentary to the Hippocratic text On Joints; manuscripts as early as the 10th-century Codex Laurentianus 74.7 show patients having their joints manipulated or bandaged, or being hoisted onto devices designed to stretch or compress the limbs. Images of the fetus in various abnormal positions appear in medieval medical manuscripts including gynecological and obstetric material, notably Mustio’s Latin version of Soranus’s work Gynaecia (see the 9th-century Koniklijke Bibliotheek van België/Bibliothèque Royale de Belgique, Codex 3701–3715, fols. 26v–29r). Quite possibly this tradition of illustrations goes all the way back to Soranus’s descriptions of the abnormal positions in which the midwife may encounter the fetus.34 Overall, however, ancient medical texts seem rarely to have been illustrated, as their references to the acquisition of anatomical knowledge point to dissection rather than study of images in books.
