A Cincinnati classicist rebuilds one page of a Roman pocket law book from seven scraps of skin
Matthijs Wibier read the faded Latin under ultraviolet light and found provisions that match no surviving Roman code, which is a real find and also a measure of how little fourth-century law survives.
The Scientist · Science desk
What happened
- Matthijs Wibier, a classicist at the University of Cincinnati, joined the seven largest of 50 animal-skin fragments held at the Penn Museum into a single double-sided page and translated the Latin on it.
- The museum bought the scraps from an antiquities dealer in Egypt in 1911, and the reassembled page is the only Latin manuscript among its hundreds of texts from Egypt.
- The decrees on the leaf belong to the reigns of Constantius II and Julian, who ruled between 337 and 363, and the hand is polished enough that Wibier reads it as a carefully produced book.
- He argues the leaf came from a small late-fourth-century compilation of imperial laws made for tax officials, landowners or their lawyers, rather than from any of the known codes.
Why it matters
- What it limits constraint So little fourth-century legal writing survives intact that the case for a book with no parallel rests on an argument from an empty shelf, and it stays revisable by the next legible fragment out of Egypt.
- What's now possible capability Ordering a leaf from the texture of the skin and the placement of red ink, rather than from continuous prose, means badly damaged manuscripts can be sequenced before they can be fully read.
- Who's exposed exposure The hundreds of fragmentary Egyptian manuscripts in the collection Jennifer Houser Wegner curates become a candidate pool worth rechecking under the same lamp, with the same physical clues in mind.
- What it sets up precedent If compact excerpt books circulated beside the enormous codes, then administrative history built on the codes has been reading the archive copy rather than the one an official carried.

Start with what fixes the page order, because it is the one part of the argument that does not depend on reading a continuous sentence. Parchment keeps a memory of the animal it came from: one face of the skin is smooth, the other more textured, and Wibier places the textured face first, as the odd-numbered page that sits on the right of an open book [7]. Three red ink highlights appear on that face and not on the reverse, and their distribution, together with which imperial decrees fall where, is what let him work out which way the leaf faced [8]. Ultraviolet light did the reading [6]; the skin did the sequencing. The second claim can be checked by anyone who handles the object, whether or not they agree about the first.
The novelty claim, by contrast, is a negative one, and it is worth saying so plainly. Wibier's line is that no book like this is known, which makes it the first of its kind [14], and Discover reports that none of the surviving Roman legal codes contains this sort of text [15]. Daniel Markovich, who heads Cincinnati's Classics department, puts it in the same shape: unlike nearly all other fragmentary Roman law books, this one corresponds to no known imperial code [16]. The denominator behind that absence is thin. Very few books from the period survive intact, which is why scholars work from damaged and partial copies at all [22]. The closest comparison, the Theodosian Code, runs to 16 books and preserves more than 2,500 decrees issued between 311 and 437 [17] - an average near 156 decrees per book [27], across a 126-year window that comfortably contains the 337 to 363 reigns behind the Penn text [28]. Wibier does not think his page came from either of the two Theodosian books covering similar subjects, and he says he cannot completely rule it out [18]. That is the right posture, and it is also the finding: this matches nothing we hold, which is a smaller statement than matching nothing that existed.
The road-and-grain provision is the most quotable line in the coverage and the softest claim in it. Wibier introduces it with a hedge of his own, saying that if he had to speculate, this was a law requiring wealthy citizens to keep roads in good repair and supply grain for the food supply [10], and the passage carrying it is damaged [11]. The warning against treating public buildings as private property arrives without that hedge [12]. The thing the leaf does not tell you is how common such compilations were, who commissioned them, or whether this copy was official. Wibier's guess that it was an official's book rests on the quality of the hand, which he calls high-end scriptorial writing [19], and on the argument that a travelling officer wanted the few rules he used rather than the thousands he did not [21]. His summary of the likely readership is blunter: to dodge the law, you have to know the law [20].
One more denominator. Seven of the fifty scraps are in the page, which leaves 43 unplaced [26], so this is part of one leaf from a book of unknown length. The full account appears as a chapter in Il Codice Teodosiano, edited by Detlef Liebs and Dario Mantovani and due this year from Pavia University Press [23], with support from the European Research Council and the Semple Classics Fund [24]. Until the images and apparatus are public, the proposition worth watching is the format rather than the tax content: evidence that imperial law reached the people who had to comply with it in editions sized for a pocket [13], alongside the vast codes that happen to be what survived.
What to watch
- Publication of the Pavia chapter with images and apparatus, which would let other papyrologists test the join and the readings.
- Whether any of the 43 unplaced fragments join this leaf or a second one, which would constrain the book's format and length.
- Whether a matching text surfaces in the Theodosian Code's transmission or another papyrus, which would collapse the no-parallel claim.

Matthijs Wibier is an assistant professor of Classics at the University of Cincinnati who edited and translated a Latin legal text pieced together from fragments.
- [2]
The 50 animal-skin fragments come from a collection of Egyptian antiquities at the Penn Museum at the University of Pennsylvania in Philadelphia.
- [3]
With the museum's help, Wibier pieced together a double-sided page from the seven largest tattered fragments.
- [4]
The Penn Museum obtained the fragments from an antiquities dealer in Egypt in 1911.
- [5]
The animal-skin page is the only Latin manuscript among the museum's hundreds of texts from Egypt.
- [6]
Wibier used ultraviolet light to draw out the contrast in the ink for the recovery of the Latin text and its translation.
- [7]
One side of animal skin is smooth and the other more textured; the textured side of the page came first, representing the odd-numbered page that sits on the right side of the book when opened, so the opposite side appeared on the left.
- [8]
One side of the page has three examples of red ink added to highlight something important, and from the absence of those highlights on the reverse side along with the imperial decrees discussed, Wibier determined which way the pages faced in the book.
- [9]
The laws on the parchment date to the reigns of Constantius II and Julian, who ruled between 337 and 363.
- [10]
Wibier said: "If I had to speculate, this was a law saying wealthy citizens had to keep the roads in good shape and provide grain for the food supply."
- [11]
Discover reports that the passage appearing to put wealthy citizens on the hook for road repairs and grain is damaged.
- [12]
Another law on the page warned people to stop treating public buildings as if they were private property.
- [13]
Wibier said the text likely came from a small compilation of imperial laws from the late fourth century that was distributed for official use by tax officials or private use by landowners or their attorneys.
- [14]
Wibier said: "We don't have a book like this that we know of, which makes it the first of its kind."
- [15]
None of the surviving Roman legal codes contains this kind of text.
- [16]
Daniel Markovich, head of the University of Cincinnati's Department of Classics, said that unlike nearly all other fragmentary Roman law books, this text does not correspond to any known imperial legal code.
- [17]
The Theodosian Code, Wibier's closest point of comparison, is spread across 16 books and preserves more than 2,500 imperial decrees issued from 311 to 437.
- [18]
Wibier does not think the Penn parchment came from either of the two Theodosian Code books covering similar subjects, although he cannot completely rule it out.
- [19]
Wibier said the page was very carefully produced, the handwriting very beautifully done, and "this is very high-end scriptorial writing", and that if he had to guess it could have been an official's book.
- [20]
Wibier said: "To dodge the law, you have to know the law."
- [21]
Wibier said he does not think the book contained thousands of laws like most known Roman codes, and that he thinks it was a book travelling officials could put in their pocket.
- [22]
Precious few books from that period survive intact, so scholars must rely on damaged or partial manuscripts to recreate them.
- [23]
Wibier described the translation work in a chapter of the upcoming book "Il Codice Teodosiano", edited by Detlef Liebs and Dario Mantovani, scheduled to be published this year by Pavia University Press.
- [24]
The project was supported with grants from the European Research Council and the Semple Classics Fund.
- [25]
Jennifer Houser Wegner, the Penn Museum's curator-in-charge for the Egyptian collection, said the museum preserves hundreds of manuscripts from Egypt, many surviving in fragments.
- [26]
43 of the 50 fragments are not part of the reconstructed double-sided page.
- [27]
The Theodosian Code averages roughly 156 decrees per book.
- [28]
The Theodosian Code's collection window spans 126 years, and the 26-year span of the reigns behind the Penn text falls inside it.
