Siege of Veii & Marcus Furius Camillus – Lecture 17 (History of Rome)

Overview

The ten-year siege of Veii (405–396 BC) was the climax of Rome's oldest rivalry and the making of its greatest early hero, Marcus Furius Camillus. Veii — wealthiest of the twelve Etruscan cities, perched on a sheer plateau behind massive walls — could not be stormed, only starved, and only Rome's new year-round army made that possible. The blockade dragged on through disasters, mutinous quarrels among the consular tribunes, the defection of the Etruscan towns Falerii and Capena to Veii's side, and the strange prodigy of the Alban Lake, whose rise sent Rome to consult the oracle at Delphi.

The turning point came when Rome appointed Camillus dictator. He restored discipline, drained the lake as the oracle prescribed, and drove a mining tunnel (cuniculus) beneath the walls that surfaced inside the enemy citadel — in the very temple of Juno, whose favor he had formally called over to Rome. Veii fell in 396 BC, drowning Rome in plunder. But Camillus' vow of a tenth of the spoils to Apollo, and a triumph staged with the regal extravagance of four white horses, planted the resentment that would soon drive him into exile. The episode marks Rome's transformation from a struggling city-state into the dominant power of central Italy.

Key Concepts

Veii — The great Etruscan city on a fortified plateau above the Tiber, Rome's nearest and oldest rival; tradition traced their enmity back to the boundary drawn at the Tiber between Latins and Etruscans. It proved to be the richest of the twelve Etruscan cities.
The year-round siege — Rome ringed Veii with circumvallation plus a northern wall against Etruscan relief, then built permanent forts and winter quarters — its first truly continuous, all-season army, kept in the field by the new stipendium.
Falerii and Capena — Two smaller Etruscan towns that joined Veii, fearing they were next; they harassed the siege lines until Camillus crushed them in the field.
Volunteer surge — After a Veientine sortie burned the siege works, Roman equestrians volunteered with their own horses and plebeians enlisted as infantry, swearing to serve "until the war is won."
Publius Licinius Calvus (400 BC) — The first plebeian consular tribune, elected amid the strain of the siege — a landmark in the plebeians' long climb toward the top magistracies.
The Alban Lake prodigy — The lake near Alba Longa rose inexplicably with no rain; read as a divine sign, it prompted an embassy to Delphi and the interrogation of an Etruscan seer (haruspex).
Delphi and the haruspex — Both the captured Etruscan seer and Apollo's oracle at Delphi gave the same answer: Veii could not fall until the Alban water was drained into the fields, never allowed to reach the sea.
The lectisternium — During a plague year the Sibylline Books prescribed this propitiation rite: couches set out for pairs of gods with public feasts, doors thrown open, prisoners freed — eight days of enforced civic harmony.
Marcus Furius Camillus — Four-time consular tribune and, in 396 BC, dictator. Stern, pious, and disciplined, he decimated the units that had fled earlier and rebuilt the army's nerve before finishing the siege.
The cuniculus — A mine driven in six-hour shifts into the plateau; it broke into a drainage channel that emerged inside the citadel's temple of Juno, letting elite troops erupt into the city while a mass assault on the walls held Veii's defenders' attention.
Evocatio of Juno Regina — Before the assault Camillus performed the evocatio, ritually inviting Veii's patron goddess Juno to abandon the city and dwell in Rome; her cult statue was carried to a new temple on the Capitoline.
The fall of Veii (396 BC) — After ten years the city was taken and sacked; its people were enslaved to refill the treasury and its immense wealth distributed as plunder — a psychological shock to all of Italy.
The tithe to Apollo — Camillus had vowed one-tenth of the spoils to Apollo at Delphi. Because the plunder was already spent, matrons donated their gold to complete a golden bowl; en route, pirates who learned it was for Apollo escorted the ship safely — a measure of the shrine's reverence.
The triumph and its cost — Camillus rode in a chariot drawn by four white horses, unseen since the kings; that, plus the tithe and a later demand to tithe the captured land's value too, made him the most resented man in Rome, setting up his exile.

Worked Example

The tenth part for Apollo — reconstructing the scale of Veii's plunder. Camillus' vow was a fixed fraction, and the tradition preserves the physical form the gold tithe finally took, which lets the arithmetic run backward.

State the vow. Camillus promised Apollo the tenth part of the spoils. If $S$ is the total value of the spoils, the tithe is

T = \frac{1}{10}\,S.

The gold bowl. The tithe was embodied in a golden krater (mixing-bowl) dedicated at Delphi, which tradition weighed at 8 talents.
Convert to mass. Taking $1$ Attic talent $\approx 26$ kg,

8 \times 26 = 208 \text{ kg of gold}.

Express in Roman pounds. With the libra $\approx 0.329$ kg,

\frac{208}{0.329} \approx 632 \text{ librae}.

Back-solve the spoils. If that bowl represents the tenth part of the gold, the implied gold-equivalent of the whole plunder was

S = 10 \times 632 \approx 6{,}320 \text{ librae} \;\approx\; 2.08 \text{ tonnes of gold-equivalent},

which is why the matrons had to make up the shortfall once the distributed loot had been spent — and why a second tithe, on the assessed value of the captured land, provoked still more fury.

The ten-year echo. Reckoning from Rome's founding in 753 BC (AUC dating), the siege ran from 405 BC (AUC 349) to 396 BC (AUC 358) — a span consciously remembered as ten years, deliberately mirroring the tenth-year fall of Troy and casting Veii as Rome's own Ilion. $\blacksquare$

Summary

Veii, an impregnable plateau fortress and the richest Etruscan city, could only be starved out — which Rome's new year-round army finally made possible over a ten-year siege (405–396 BC).
The Alban Lake prodigy and the matching verdicts of the Etruscan haruspex and the Delphic oracle tied victory to a religious act: draining the lake into the fields.
Camillus, made dictator, restored discipline, drained the lake, called Veii's Juno over to Rome (evocatio), and won the city through a mining tunnel that surfaced in her temple.
The fall of Veii in 396 BC flooded Rome with plunder and enslaved captives, stunning all of Italy and marking Rome's rise to regional dominance.
Camillus' vowed tithe to Apollo and his regal four-white-horse triumph turned admiration into resentment — the seed of the exile to come.
