Real and fictional

Fictional Made up for the Short

  • Felix
    Felix

    A baker. He stands in for the thousands of people in Pompeii whose names we'll never know.

  • Tullia
    Tullia

    His daughter, about eight. She stamps the loaves.

Real Documented

  • Days of small earthquakes before the eruption, shrugged off as normal for Campania.1

  • The eruption column at about 1 pm, shaped like an umbrella pine.1

  • Pumice and ash falling all afternoon and night.2

  • Round loaves scored into eight wedges, marked with the maker's bread stamp.5

  • 81 loaves found in a sealed bakery oven in 1862.4

The day, hour by hour

  1. For days before

    The ground keeps shaking

    Pliny the Younger writes that tremors had been felt for many days. They caused little alarm, because earthquakes were common in Campania.1 Parts of the town were still being rebuilt after a large earthquake in 62 or 63 AD.6

    Tullia, worried
    TULLIA

    Papa! The ground is shaking again!

  2. 24 October · morning

    An ordinary working day

    Pompeii's round loaves were scored into eight wedges before baking, and bakers pressed a stamp into the dough to mark whose bread it was.5

    Felix, smiling
    FELIX

    Eighty-one loaves today. Best bread in Pompeii.

  3. About 1 pm · the seventh hour

    A column like an umbrella pine

    Across the bay at Misenum, Pliny's mother pointed out a cloud of unusual size and shape. Pliny compared it to an umbrella pine: a tall trunk rising high, then spreading out at the top.1

    The eruption column rising over Vesuvius, the sky turning brown.

  4. Afternoon to night

    Stones from the sky

    Pumice and ash fell on Pompeii for 18 to 20 hours, building up to 2.8 metres deep.2

    Felix, afraid
    FELIX

    Leave the bread. Take my hand. RUN.

  5. 25 October · early morning

    The surges

    Pyroclastic surges, fast clouds of hot gas and ash, reached the town. Those still in the town were killed.2

  6. 1748

    Rediscovery

    Excavation began about 1,670 years after the eruption.7

1862. Archaeologists open a bakery oven in Pompeii.

Inside: 81 loaves of bread.

Felix is fictional. The bread is real.

Every line, checked

Each line from the Short that makes a historical claim, beside what the record says.

On screen · opening

To everyone here, the mountain is just a mountain.

The record

Vesuvius looked dormant, and vineyards grew up its slopes. Romans knew about volcanoes in general, but people in Pompeii probably did not think of this mountain as one in any practical sense.89

FELIX

Eighty-one loaves today. Best bread in Pompeii.

The record

The number comes from the find: 81 carbonised loaves in the oven of the Bakery of Modestus.4 Some accounts count 80. Whether they were being baked that day or stored is debated. Felix's boast is our invention.

It shakes every week. The gods owe us some quiet.

The record

Pliny writes that tremors had been felt for many days and caused little alarm, because they were common in Campania.1 "Every week" is our dramatisation.

Pliny dates the column to about the seventh hour, roughly 1 pm.1 The date itself is this entry's open question.

The pumice phase of the eruption lasted 18 to 20 hours and left up to 2.8 metres of pumice on Pompeii.2

The town is buried. It sleeps for almost 1,700 years.

Open question

Open question

Why does the Short say October, not August?

Traditional24 AUG 79 AD
From copies of Pliny's letter
Favoured24 OCT 79 AD
After the 2018 inscription

For centuries the eruption was dated to 24 August, from medieval copies of Pliny's letter. In 2018, archaeologists in Pompeii found a charcoal scribble on a wall dated to 17 October. Charcoal fades fast, so it was most likely written that same October, a week before the eruption.310

Most experts now lean towards 24 October, but it is still debated.

Contested

Think about it

  1. People in Pompeii lived with frequent earthquakes. Why might a familiar warning sign be easier to ignore than an unfamiliar one?
  2. Pliny wrote his letters about 25 years after the eruption, at the historian Tacitus's request. How should that change the way we read them?
  3. The date rests on copied manuscripts and one charcoal note. What other kind of evidence could help settle it?
  4. The Short invents Felix to tell a real story. What does a fictional character let a storyteller do, and what are the risks?

Glossary

Plinian eruption
A violent eruption that drives a tall column of gas and pumice high into the sky. Named after Pliny's description.
Pumice
Light, frothy volcanic rock full of gas bubbles.
Pyroclastic surge
A fast, ground-hugging cloud of hot gas and volcanic debris.
Carbonised
Turned to carbon by heat without burning away, so the object keeps its shape.
Panis quadratus
The Roman round loaf scored into eight wedges, the kind found in Pompeii's ovens.
Campania
The region of southern Italy around the Bay of Naples.
