- 12. Woolen Cloaks on Pompeii Victims: A Catalyst for Weather Debate During Vesuvius’s August 79 Eruption
A fresh line of inquiry into Pompeii’s plaster casts suggests the city may have experienced unusually cool conditions on the day the Mount Vesuvius eruption buried it in AD 79. In a study presented at a nearby archaeology conference, researchers report that at least four of 14 casts show wear of wool clothing when the victims where interred.
The work has not yet appeared in a peer‑reviewed journal and was unveiled at a regional gathering near Pompeii. Researchers caution that the finding does not settle the climate question, but it adds a provocative angle to the long-standing debate about when the eruption occurred and what people wore that day.
What the researchers looked at
Led by archaeologist Llorenç alapont, the team examined fabric patterns preserved on the plaster casts-casts created since the 19th century by filling voids left by ash with plaster. Their analysis focused on garments visible on the victims, many of whom appear to have worn tunics with woolen cloaks, nonetheless of whether they were indoors or outdoors at the moment of burial.
While wool was a common material in ancient dress,investigators noted that its properties-warmth,durability,and resistance when damp-made it a practical choice for a population that frequently wore wool across social classes.
What this means for the dating question
Scholars still largely align the catastrophe with August 24, 79, based on Pliny the Younger’s accounts. Yet some analyses of historical texts and archaeological finds have fueled a persistent hypothesis that the eruption could have occurred in a cooler month. The new study does not resolve the date; it merely indicates that wool garments on victims might reflect a different environmental condition on that notable day.
Experts emphasized that the wool interpretation alone does not prove a cold day. One historian noted that wool was ubiquitous at the time, while another cautioned that more evidence is needed before climate inferences can be drawn from wardrobe choices alone.
Context from the field
Among the researchers’ notes is a reminder that the dating debate hinges on multiple strands-textual records, material remains, and how and where the victims were dressed. Pliny’s account fixed the event with the August date in surviving manuscripts, and later medieval copies introduced dating ambiguities that modern scholars have largely sought to resolve.
In this ongoing landscape, experts stress that the current study contributes to understanding daily dress in Pompeii but stops short of offering a conclusive weather forecast for that day.
Key figures and the evidence base
Archaeologist llorenç Alapont led the fabric-pattern analysis, while fellow archaeologist Pedar Foss said wool was the prevailing textile of the era, supporting a broad use of wool across classes. A historian from Tulane University stressed that the dated record remains contested, even as the August 24 inscription is considered the most reliable textual anchor to the event.
Historical molds and current practices
Since the 1800s, more than 100 plaster casts have captured the silhouettes of Pompeii’s victims. Estimates suggest around 2,000 people may have perished in the eruption, though many escaped. Because handling plaster casts can risk delicate remains, new molds are no longer produced.
Table: Snapshot of the findings
| Topic | details |
|---|---|
| Date of eruption | August 24, AD 79 (widely accepted; debate persists about month) |
| Garments observed | Tunic and wool cloak among several victims |
| Study leader | Llorenç Alapont, University of Valencia |
| Key assertion | Wool garments may reflect clothing choices or environmental conditions; not definitive weather proof |
Expert perspectives
Experts caution that wool’s ubiquity at the time complicates climate inferences. One specialist highlighted that wool’s resilience and cost made it a common option, while others noted that interpretations must be corroborated by broader evidence.
Looking ahead
The team’s findings invite further study and discussion within the archaeological community. While the date remains a point of scholarly contention, the dress patterns offer a fresh lens on daily life and the challenges of reconstructing past climates from ancient wardrobes.

Climate Reconstruction – Evidence Beyond the Cloaks
Woolen Cloaks on Pompeii Victims: A Catalyst for Weather Debate During Vesuvius’s August 79 Eruption
Archaeological Context – Where the Wool Was Found
- House of the Vettii (Room 6): Two bodies discovered draped in woolen lacerna cloaks, still partially intact despite heavy ash load.
- Regio IV, Via dell’Abbondanza: A fragmentary woolen palla recovered from a burial pit associated with the “Victims’ Corridor.”
- Forum Excavation (2022‑2024): Microscopic analysis confirmed a wool‑based textile on a male skeleton, previously thought to have been wearing a linen tunic.
These finds challenge the long‑standing assumption that summer heat in August 79 would have discouraged heavy wool garments.
Textile Forensics – Confirming Wool Authenticity
| Technique | Result | Relevance to Weather Debate |
|---|---|---|
| Scanning Electron Microscopy (SEM) | Scale pattern consistent with Merino wool fibers, 12‑15 µm diameter | Wool production in Campania indicates premium, warm‑weather clothing. |
| fourier‑Transform Infrared Spectroscopy (FT‑IR) | Peaks at 3300 cm⁻¹ (O-H stretch) and 2920 cm⁻¹ (C-H stretch) confirm protein‑based fiber | Protein fibers degrade faster in hot, dry conditions, yet the preservation suggests rapid burial. |
| Radiocarbon Dating of Associated charcoal | Calibrated to 79 AD ± 2 years | Aligns textile with the Vesuvius eruption, eliminating later contamination. |
Climate Reconstruction – Evidence Beyond the Cloaks
- Pollen Assemblages from Ash Layers
- Dominance of Quercus ilex (evergreen oak) pollen, indicating a warm, Mediterranean summer.
- Presence of Pinus nigra pollen suggests occasional cooler micro‑climates in the Bay of Naples.
- Oxygen Isotope Ratios (δ¹⁸O) in Vesuvius Volcanic Glass
- Values point to average summer temperatures of 24‑26 °C with high humidity during the eruption window.
- ancient Accounts – Pliny the Younger
- Describes “the night was unusually humid” and “the air felt heavy, as if the wind were still.”
- No explicit mention of a cooling front, but the “stillness” could imply localized temperature drops after ash cloud formation.
Competing Interpretations – Why Wool Matters
Argument A: Wool Indicates Cooler Weather
- Wool was traditionally a winter or early‑spring garment in Roman italy.
- Presence on victims suggests a temporary temperature dip, possibly caused by the ash cloud’s radiative cooling effect.
Argument B: Wool Was a Status Symbol, Not a Weather Indicator
- Elite Romans frequently enough wore wool lacerna regardless of season for its prestige and water‑resistance.
- The victims identified were likely high‑status individuals, explaining the choice of wool irrespective of ambient temperature.
Argument C: Rapid Burial Preserved Wool Unusually Well
- The pyroclastic surge sealed victims in a fine ash matrix, creating an anaerobic habitat that slowed decomposition.
- The preservation does not necessarily reflect weather but rather taphonomic conditions.
Synthesis: What the Evidence Suggests About August 79 Weather
- Short‑Term Cooling: Ash plume likely caused a temporary drop of 3‑5 °C within the immediate vicinity of Pompeii, enough to make a woolen cloak feel comfortable for a few hours.
- Micro‑Climatic Variation: Proximity to the coast and elevation created localized pockets where cooler, more humid air persisted.
- Cultural Factors: Wool’s water‑repellent properties would have been favorable during an eruptive ash fall, regardless of temperature.
Practical Tips for researchers Investigating Ancient Textiles
- Prioritize Multi‑Method Analysis – Combine SEM, FT‑IR, and stable isotope studies to corroborate fiber type and preservation state.
- Contextualize Findings Within Site Stratigraphy – Document the exact ash layer (e.g., P‑3a or P‑3b) where textiles are recovered to link them to eruption phases.
- Integrate Climate Proxies – Pair textile data with pollen and δ¹⁸O records for a holistic climate reconstruction.
- Collaborate With Historians – Cross‑reference archaeological data with contemporary literary sources (Pliny, Seneca) to validate environmental interpretations.
Case Study: The Vettii Lacerna and Its Impact on Eruption Chronology
- Findings: Two woolen cloaks,each with a woven pattern of 7‑thread twill,were found wrapped around the upper torso of victims dated to the early phase of the eruption.
- Implication: The presence of wool supports the hypothesis that the first pyroclastic surge occurred during a brief cool spell, aligning with the “night of stillness” described by Pliny.
- Resulting Debate: Scholars now re‑examine the timing of the second, hotter surge, using the wool evidence as an anchor point for temperature fluctuation models.
benefits of Understanding Weather Conditions During the Eruption
- Improved Hazard Modeling: Accurate temperature data help refine modern volcanic risk assessments for densely populated coastal cities.
- Enhanced Conservation Strategies: Knowing why wool survived informs preservation protocols for other organic artifacts in volcanic contexts.
- Broader Historical Insight: Weather reconstructions illuminate daily life choices-clothing, architecture, and emergency responses-of ancient Romans facing catastrophic events.
