LATER BESTIARY WITNESS · DOES NOT ILLUSTRATE THE VIRGIN-CAPTURE STORY
Two of our sources describe the same one-horned animal and disagree about the one thing everybody remembers. Isidore says it can be caught, with the help of a girl. The Aberdeen Bestiary says no one has ever taken one alive.
The heading De monocero falls at the foot of f.14v. The text and the miniature are on f.15r.
A horse’s body, an elephant’s feet, a tail like a deer’s, a terrible bellow, and one horn four feet long.
Too strong for any hunter to take by force. A girl is set before it; it lays its head in her lap and is caught.
It can be killed, but it cannot be captured. No living monoceros has ever come into human hands.
The later manuscript does not just add to Isidore here. It denies him.
THE LAYERS · KEPT DISTINCT
ISIDOREETYMOLOGIAE XII.2.12–13
Isidore’s entry opens with the rhinoceros, named in Greek for the horn on its nose, and gives monoceros, the unicorn, as its other name: an animal with a single horn in the middle of its forehead. It is so strong that no hunter can take it by force. A girl is set before it; it lays down its ferocity, rests its head in her lap, and is caught.
PHYSIOLOGUS LINEVIRGIN-CAPTURE ALLEGORY
The virgin-capture story is also carried by the Physiologus tradition, where it is read as an allegory. The chapter and version are not cited on this page yet. VERSION-SPECIFIC SOURCE REQUIRED.
MANUSCRIPT WITNESSABERDEEN MS 24 · f.14v–15r
The Aberdeen monoceros is a composite monster: a horse’s body, an elephant’s feet, a deer-like tail, a terrible bellow, and a sharp horn four feet long. The text says it can be killed but never captured.
The painter did not follow the words exactly. The university’s commentary describes the miniature with a stag’s head and a boar’s tail, and links the image to descriptions of the Indian rhinoceros. The miniature on f.14v, just before, shows two goats and is unrelated.
HOW WE KNOW WHAT WE THINK WE KNOW
Isidore XII.2.12–13 checked in two online editions. The entry begins with the rhinoceros.
Aberdeen f.14v and f.15r checked on the University of Aberdeen’s folio pages, including the no-capture statement and the miniature commentary.

Aberdeen’s comparison of f.9v–10r says leaves for antelope, unicorn, lynx, griffon and the elephant illustration are missing there. That lost unicorn entry is distinct from the later surviving De monocero text at f.14v–15r.
Record levels, status labels, the streams diagram and the interface framing are authored by Make It Believable. They are not historical testimony.
WHAT WE DO NOT KNOW YET
- Which earlier author the surviving Aberdeen De monocero text follows. Earlier notes linked it to Solinus; the f.15r folio page names no source.
- The Physiologus chapter and version behind the virgin-capture allegory.
