On the morning of 15 March 44 BCE, the day Spurinna had named as the edge of the danger he foresaw, Suetonius records that Caesar encountered Spurinna on his way to the Senate. Caesar joked to him that the Ides of March had come without any harm befalling him, treating the warning as one that had simply failed to materialize. Spurinna answered that the Ides had indeed come, but had not yet passed. Caesar was stabbed to death in the Senate within hours of that exchange.
Nothing else about Spurinna's life is recorded in the surviving sources. He appears in the historical record for this single episode alone, remembered entirely for a warning that turned out to be accurate to the day rather than for anything known about his training, his other clients, or the rest of his career as a haruspex.
He is not the same person as Titus Vestricius Spurinna, a Roman senator and consul who lived roughly a century later, from about 24 CE to sometime after 105 CE. The two men share only a family name, separated by more than a hundred years and by entirely different careers, one a religious specialist remembered for a single omen and the other a senator of the high empire; this record keeps that distinction rather than repeating a conflation the shared name has sometimes invited.
The haruspex and the senator are separated in every particular but the name they happen to share, and treating them as one figure would fold a documented Roman consular career into an episode that in fact ended, for its own Spurinna, with a single exchange outside the Senate on a March morning a century before.
