The Islands

A remarkable 10th-century manuscript from southern Italy, perhaps from Monte Cassino, reveals  some of the first tender shoots of medieval illustration. Vat.lat.3342, just digitized by the Vatican Library, is a copy of Solinus's Collectanea rerum memorabilium (above), a compilation of marvels such as lotus-eaters, Amazons and the Blemmye with eyes in their chests and other racy bits from Pliny's Natural History.

There are no monsters in this codex, but a user has added little sketches of the islands of the world and their characteristic forms, as taught in schools since antiquity. Here are Corsica, Sardinia, Sicily and Crete:

Britain has the scholiast stumped: how on earth is it shaped? Too weird. So he leaves it out, providing the gloss only in his own Carolingian-style handwriting. In the case of Taprobane (modern Sri Lanka), no one knows what is there so he shows it as an empty blob:

The main script is Beneventan according to Lowe, or as an earlier librarian called it on the flyleaf, lettera longobarda. Patrick Gautier Dalché, who notes that this the oldest extant manuscript of Mommsen's Class I of Solinus witnesses, identifies the glosses as coming from the Historiae of Orosius.

In Latin antiquity it was more or less settled that the known world comprises three continents and six main islands. The shapes were taught to help the student remember islands by their classically known outlines: much indented Corsica, four-cornered Sardinia, triangular Sicily, elongated strip-like Crete and pear-shaped Sri Lanka.

Lectio Brevior

It's a modest little drawing at the bottom right corner of a page, yet it's a key to the history of visualization. Last week I blogged about the little T-O map attached in late antiquity to the Jugurthine War by Sallust, but could only offer you a much padded example with lots of medieval additions.

This week, the Vatican Library has digitized a purer example, one of the oldest surviving. It dates from the 10th century, is quite simple, and must be much closer to what a late-antique grammarian doodled on a Sallust text to assist students: a circle marked east at top, with half its surface marked Asia and the rest divided between Europe and Africa:

It appears in Vat.lat.3326, a Sallust codex containing the Bellum Catilinae, the Bellum Iugurthinum, and the spurious Epistulae ad Caesarem senem (Letters to Caesar in his Later Years), and as you can see, this week's diagram is less wordy than that of last week in Vat.lat.3328 (dated to the late 10th or early 11th century):

Text scholars generally apply a rule, lectio brevior praeferenda, whereby the less wordy of two versions is assumed to be the older one. Scribes and editors tended to augment texts, not to cut them.

Here is the full list of new digitizations:
  1. Chig.E.VII.215 (Upgraded to HQ), book of recovered manuscript fragments
  2. Ott.lat.3372,

Map of War

One of the more mysterious of ancient diagrams is a T-O "map" found in medieval manuscripts of the Jugurthine War by Sallust. Who drew it? I've been gathering information about this in the last few weeks, so it was a pleasant surprise to see the diagram pop up in this week's list of Vatican Library digitizations:
This version in Vat.lat.3328 which is dated to the end of the 10th or start of the 11th century is perhaps of German provenance. Curiously the codex has been rebound at some stage using strips of parchment from a newer manuscript in 13th-century Beneventan writing to strengthen the binding (noted by Lowe of both this codex and Vat.lat.3262.)

Asia, and thus the direction east, is at the top in this version of the diagram, which has been much "improved" by the scribes with extra toponyms. Other recensions of the graphic are rather bare.

Where does it come from? I would be highly sceptical of the claim that Sallust himself drafted the diagram while writing his history of a war in North Africa, since visualizations of this sort were not a part of the literary man's repertoire in the classical period. So the diagram may well be an addition by a late antique grammaticus.

Patrick Gautier Dalché has written a series of splendid syntheses about such diagrams where he argues that their models arose in education in the 4th to 6th century (see below). Whether any scholar has yet collated the Jugurtha's World diagram and constructed a stemma of its development I simply don't know yet.

Recently I added a couple of mappamundi to my Library of Latin Diagrams, and the Jugurtha T-O will join the collection later, once I have figured out what the prior recension is.

Before proceeding to the full list of 42 new items of the past week on the Vatican portal, I must recommend a series of more than 100 tweets with the tag #PolonskyProject posted on May 30 by participants at a one-day conference at the Vatican about the future of manuscript digitization. I wasn't present unfortunately, but am grateful that someone in the audience asked why the Library puts an ugly ownership watermark on its online images:

Cicero's Witness

I've blogged a couple of times before (here and here) about the world's most famous unreturned library book, the unique copy of Cicero's guide to oratory in the bishop's palace at Lodi. It has not been seen since 1425, but fortunately multiple copies were made before it vanished.

This week, the Vatican's digitization portal placed online Vat.lat.3237, a valuable secondary witness to the content of the so-called Codex Laudensis.

There's a detailed article by Paola Scarcia Piacentini, La tradizione laudense di Cicerone ed un inesplorato manoscritto della Biblioteca Vaticana (Vat. Lat. 3237), about it. De Oratore, as I have mentioned, is especially important as a source for Cicero's theories of memory and visualization, and thus a landmark in the history of cognitive science.

Via Appia Found on Satellite Image

The Appian Way is perhaps the world's most celebrated road. On the outskirts of Rome it is a major tourist attraction. I have just discovered you can see some of its far reaches on photographs from space.

The Way seems to be the source of a common misconception in the English-speaking world that all Roman roads were solidly paved and ran straight as a laser, up hill and down dale, never yielding to the lie of the land. Beyond Terracina, much of the Via Appia was neither paved nor straight, but wriggled along long-worn prehistoric ridgeway routes, where the ground was drier (and harder) and the traveler had the best chance of spotting approaching attackers, whether they were bandits or bears.

Begun under the direction of Appius Claudius, a consul, in 312 BCE, the Via Appia initially connected Rome to Capua near Naples. Later it was extended to Brindisi on the Adriatic Coast. It was any physical traces of this latter extension that I was hoping to find while on a visit last week to Italy.

We were staying in the newly elegant city of Matera which is dolling itself up to be one of two European Capitals of Culture of 2019. In Roman times, Matera was just a remote warren of hand-hewn caves, never mentioned in the ancient sources. Perhaps it was a refuge of the above-mentioned bandits, who could murder a merchant on the Via Appia at dusk and carry the booty 15 kilometers away to the caves to hide it, safely holed up by midnight like the Ahlbergs' brigands:

Near Matera one finds two modern highways named Via Appia. The one beginning from Ferandina, national highway SS7, and proceeding via Matera to Massafra is a fake, although it too terminates at Brindisi. The other, Puglia provincial road SP28, marked "Strada Provinciale Appia" on maps, is, in some stretches at least, the real thing.

Recent articles by Luciano Piepoli dispense with the armchair scholarship (mainly German) about this part of the Via. They assemble new hard archaeological evidence about its course and stage-stops. Unfortunately Piepoli does not provide GIS geolocations (this ought to be prescribed by the style guides of every journal dealing with historical geography). He writes:
The Appian Way, at the exit from the current town of Gravina in Puglia, begins its path in a south-easterly direction near Scomunicata and, after having touched the localities of Graviscella and Ponte Padule Cardena, reaches the rocky outcrop of the Murgia Catena, located about 7 km southeast of Altamura. The road runs along the southern slope of this last location to Iesce, where there are the remains of an important settlement that had been abandoned by the 2nd century B.C. On the territory of Altamura, in a flat section between the southern slope of the Murgia Catena and the hillock of Montepovero, the projecting traces of wheel ruts are visible in the rocky surface for a length of about 200m and a total width of more than 30m, forming multiple lanes. Although they are not contemporary with one another, it appears highly probable by virtue of their topographical location that some of them must derive from the consular Via Appia. (My English, helped by Apple and Google Translate).
Hoping to see these traces of the wheels of ancient or medieval carts, we stopped our car on the shoulder of the SP28 at what we thought was the spot. Since a narrow lane of wheat was growing there on the verge of the road itself, we searched the rocky field behind it, but to no avail. On the point of giving up, and after nearly stepping on a sturdy snake, I finally discovered the ruts further up the road.

In the 50-second video above you may hear a cicada and will see the colorful wild flowers of a southern Italian spring including tall fennel, all growing in the dirt that has collected in the ruts.

The most pronounced track is at the left, close to the dry-stone wall. There are no doubt specialists who could estimate from the wheelbase whether this track is ancient or medieval. A second, shorter bunch of tracks can be found about 50m further down the hill (in a 24-second video). I have uploaded videos of both to my YouTube Channel.

The greatest surprise came later: these ruts are visible on common garden satellite imagery. When I studied the same location on Google Maps later, I was amazed to see the big set of ruts quite clearly at the location 40.76424, 16.61516 (tip: copy just this to any sat-nav or mapping app to find it):

As far as I know, this remarkable, aerially visible archaeological site is not listed on any of the ancient geographical portals such as the Digital Atlas of the Roman Empire, Pelagios or Vici. I can see how to add it to Vici (and will add it later), but I must admit that I have no idea yet how to contribute it to the former two. They do not offer any "guide for dummies" instructions.

These stone remains are no longer 30 meters wide, since the new road passes through the middle, and they do not seem to have gained any legal protection, although the feature is surely known locally. The IGM map of 1919 (reproduced as British AMS M791 of 1939) labels a nearby stretch of the road "od via antica Via Appia" (I don't know what "od" means).

Piepoli relies on a survey of the area by the great aerial archaeologist of the 1920s to the 1950s, Giuseppe Lugli, so I presume these remains are mentioned in Lugli's books or articles. As far as I can tell, they are the only surface evidence left of the ancient Via Appia between Gravina and Tarento.

The fact that wheels ran across bedrock here is an indication that the highway was unpaved. A few kilometers away, the route has been archaeologically excavated. Piepoli writes:
Near Masseria Capitolicchio Vecchia, recent excavations conducted by the Archaeological Superintendency of Puglia have highlighted a short stretch (about 200 x 4.90 m) of a road - of the glareata type - interpreted, on the basis of the construction technique, orientation and topographic context, as a segment of the Appian Way [Mattioli, 2002]. An interesting fact which emerged during the excavations is that the roadway is partially obliterated by a layer of relative collapse likely due to a structure located near the road axis. The ceramic finds and coins found can be dated between the end of the 2nd century BC and the 3rd century AD, which could be considered as a terminus post quem for the abandonment of the Via Appia in this section.
The simple glareata road had a base of stones, built up to a sand or gravel surface, and would be kicked or ground apart by heavy traffic if it were not maintained. This is probably what happened at 40.76424, 16.61516, exposing the bedrock to the grinding of cart and carriage wheels. Above, I mentioned a narrow crop of wheat growing in the queen's acre (the roadside). It too is clearly visible in the space imagery, and occupies what seems to have once been a ford through a seasonal stream, the Vulle. No doubt the silt, organic particles and the churning of the wheels created a fertile slough in this rocky landscape which, as the 1919 map shows, travelers had to edge around.

Most of the Via Appia in this area follows the watershed. Here's a more open location, looking towards the Murgia Catena from the north-west, where you may be able to see that the land slopes very lightly away to both sides.

To the left of this spot, the drop to the base of the valley is quite substantial, as the next image shows:

In an article this year, the scholar Tønnes Bekker-Nielsen compares the posterity of this southern Via Appia built in the 3rd century BCE to the highly engineered Via Traiana built with cuttings and bridges in the 2nd century CE. The bridges ultimately fell down, whereas the prehistoric footpaths and droving tracks along the watersheds proved indestructible. The self-maintaining character of ridgeway routes even after all their gravel has eroded away is the reason that the Via Appia remained in continuous medieval and modern use and was then resurfaced in the 20th century:
For the Roman traveler, the Via Traiana was a significant improvement. It was shorter, had far fewer inclines and declines and was less vulnerable to snowfall. But despite the many advantages of the Via Traiana, it is the Via Appia which has survived to this day. An estimated 90% of the total length of the Appia is still in use as graveled or asphalt road. Large portions of the Via Traiana, on the other hand, are overgrown and impassable. (My assisted translation from the Danish.)

First Accounting Handbook

Luca Pacioli, the mathematician who instructed Leonardo da Vinci and for a time lived in the same house, hand-wrote a remarkable textbook, the Tractatus mathematicus ad discipulos perusinos, for his students at the University of Perugia, where Pacioli taught from 1477 to 1480.

This celebrated source-book of merchant arithmetic, preserved as Vat.lat.3129 at the Vatican Library, is seen as the start of the formal study of accounting. A color scan has just been presented online, replacing a murky black and white image on the library portal.

Early Physics

Basic ideas of modern physics go back well beyond Isaac Newton to the English scientist Richard Swineshead, who enters the scene in about 1340 as one of the Oxford Calculators. These brilliant men were interested in velocity, force and other values, and drew on mathematical work by Thomas Bradwardine (c.1300 – 26 August 1349), who went on to become Archbishop of Canterbury.

Younger scholars were hard pressed initially to make sense of their equations, and this week's batch of Vatican Library digitizations includes one codex, Vat.lat.3064, with traces of that student shock. I will let John E. Murdoch's Album of Science: Antiquity and the Middle Ages, Topic 256, (1984) take up the story:
Another tractate of Swineshead's Liber calculationum applied Bradwardine to a quite specific problem. Briefly put, the problem was whether a thin rod in free fall near the center of the universe will ever reach that center in the sense that the center of the rod will eventually coincide with the center of the universe. The problematic part of the question derived from the fact that as soon as any part of the rod passes the center of the universe, that part may be considered a resistance against the rod's continued motion.

Assuming that the rod acts as the sum of its parts and that the relevant forces and resistances determined by these parts follow Bradwardine's "law," Swineshead concludes that the center of the rod will never reach the center of the universe (which is correct, under the assumptions made, since the time intervals for each increment of distance will increase ad infinitum). The marginal sketch [...] accompanies this particular text of Swineshead in a fourteenth-century manuscript of his work. Possibly drawn by a reader trying to puzzle his way through this segment of the "Calculator," the rod (here termed terra simplex to indicate that it is a heavy body) is appropriately divided into parts, one of them depicted as already having passed the center of the universe, which is duly labeled centrum mundi.
