Livy's account places the completed code's public display in 449 BCE: the consuls Lucius Valerius Potitus and Marcus Horatius Barbatus had the decemviral laws engraved on bronze and set up publicly before leaving Rome on campaign.
The traditional legal account adds that the collection was ratified by the Centuriate Assembly and displayed near the Curia in the Forum. Ancient and modern accounts differ over whether approval came in stages or all at once in 449.
Livy says bronze; the transmitted text of the jurist Pomponius says ivory, possibly a corruption — so the material belongs to a particular tradition rather than to established fact.
Not Rome's first laws
The Tables were Rome's earliest surviving written legislative corpus, not the beginning of law or legislation there.
The reconstructed provisions cover court procedure, judgment debts, family authority, inheritance, property, funerals, public rules and offences. One gave a judgment debtor thirty days to pay before coercive enforcement could begin — and enforcement could run to seizure, bonds and fetters.
It was not a comprehensive modern-style code, and it was not balanced between the orders: the supplementary material forbade marriage between patricians and plebeians, a ban repealed by the Lex Canuleia in 445 BCE.
What we can and cannot know
No original tablet survives. The text is reconstructed from quotations and paraphrases in later Roman authors, so the table-by-table arrangement in modern editions is a reconstruction, not the intact original.
The whole narrative comes from sources written centuries afterwards, especially Livy and Dionysius of Halicarnassus, and modern scholarship debates almost every element of it.
Public display also did not mean universal literacy or practical legal access, and later Roman law was substantially transformed by statutes, praetorian edicts, juristic interpretation and imperial enactments.

What the sources leave uncertain
- The 451–449 narrative comes from sources written centuries later, especially Livy and Dionysius of Halicarnassus. Modern scholarship debates almost every aspect of the traditional creation story.
- No original tablet survives, and the text is reconstructed from quotations and paraphrases in later Roman authors.
- Livy says bronze; the jurist Pomponius’ transmitted text says ivory, possibly reflecting a textual corruption. The tablets’ material therefore should be attributed to particular traditions.
- Ancient and modern accounts differ over whether approval occurred in stages or whether the completed collection was ratified in 449.
