Recovered text
Read end to end — the lower parts of about twenty-two columns across roughly 1.4 m of papyrus, transcribed and reviewed by papyrologists. A philosophical treatise on ethics; the evidence points to a Stoic work, and its final preserved column names Aristocreon, nephew and disciple of the Stoic Chrysippus, placing it in the 2nd century BC.
⚠️ Only the compact inner core survives — about 8 cm of an original 19–24 cm height — after earlier attempts to open the scroll by hand destroyed its outer layers, so only the lower parts of the columns remain.

About this scroll
Scroll 4 — the first Herculaneum scroll virtually unwrapped and read in full, end to end, without ever being physically opened. Scanned and read at 2.4 µm.
PHerc. 1667 is a rolled Herculaneum papyrus from the Biblioteca Nazionale di Napoli, carbonized during the eruption of Mount Vesuvius in 79 AD. It was first scanned at the Diamond Light Source in Oxfordshire, UK (2023, at 3.24 µm and 7.91 µm), and later rescanned at 2.4 µm at the ESRF in Grenoble, France (2025) — the scan from which it was virtually unwrapped and read in full. It is similar in size to PHerc. 332 (Scroll 3).
