Around 471 BCE, roughly 9,000 ostraka were dumped in the Kerameikos—ballots from a single ostracism round. Names, insults, and repeated hands reveal mass participation and organized blocs as Athens disciplined a towering figure in the wake of the Persian Wars [11][12].

What Happened

In a pit by the Kerameikos—the cemetery at Athens’s northwest gate—archaeologists uncovered a mountain of voices. Roughly 9,000 ostraka, the clay ballot-shards of an ostracism, lay in a single deposit, datable to about 471 BCE. Their red-brown faces carried names scratched in blackened lines, some neat, some jagged, a few threaded with insults [11].

The hoard is a crowd captured in terracotta. Here are repeated hands: dozens, sometimes hundreds, of sherds written by the same person, then distributed for others to cast. There are slogans and reasons squeezed around names. There are spellings that trip and jokes that bite. Together, they reveal what literary sources only hint: hetaireiai, political clubs, organized writing, and campaign-style coordination inside a mass vote [11][12].

The city around them gives context. The Pnyx had decided whether to hold the ostracism. The Agora’s fenced precinct hosted the casting, the Stoa of Attalos’s long shadow shielding part of the queue. The Acropolis loomed; Piraeus’s masts crowded the horizon. When the vote ended and the target was named, the ballots were swept away and dumped beyond the gate, near the graves. Their clatter would have echoed off stone. Then silence.

Plutarch’s canonical description sits behind the heap: a 6,000-vote quorum or the ostracism failed; ten days to leave Attica; ten years away, property and citizen status preserved [2]. The hoard adds flesh. It shows the social mechanics by which names gained momentum: pre-written shards, common slogans, coordinated inscriptions that increased efficiency for voters less comfortable writing or simply eager to hurry [11][12].

The date aligns with the traditional ostracism of Themistocles, the war leader whose naval genius at Salamis now proved unsettling to rivals and citizens alike. Whether every shard aimed at him or not, the cache evokes the moment when his name moved from laurel to liability [1][11][17]. A scarlet thread of irony runs through it: the city trimmed the man who saved her, using the very democratic tool created to prevent another kind of savior from becoming a master.

Held in a museum case, the 9,000 sherds look like rubble. Read as a document, they form the noisiest text in Athenian political history: 9,000 tiny votes scratching at the edges of power and pushing a giant toward the gates [11][12].

Why This Matters

The Kerameikos hoard gives ostracism its fullest material archive. It documents scale (c. 9,000 ballots), coordination (repeated hands, slogans), and voter expression (insults, reasons), complementing Plutarch’s spare procedural outline with the social textures of a mass vote [2][11][12].

The deposit brings the theme of elite coordination into focus. Hetaireiai and activists pre-wrote ostraka, distributed them, and amplified campaigns within a formally egalitarian process. The shards show how elites could steer outcomes without controlling them, and how the demos’s anonymity mingled with organization [11][12].

Within the broader story, the hoard likely touches the moment of Themistocles’s banishment, anchoring a major political shift in physical evidence. By the time Athenians reached for shards against Cimon and later Thucydides son of Melesias, this blend of mass participation and coordinated effort was a familiar feature of the ritual [1][18].

For historians, the hoard transforms ostracism from an abstract constitutional device into a participatory practice with measurable patterns. It supports political-economy models of strategic voting and illustrates how democratic forms absorb and channel elite activism [11][12][14].
