Did Rome Parade the Sacred Objects Taken from Yahrushalam Through the Streets of Rome?
Event: Flavian triumph, Rome, 71 CE · Primary: Josephus, The Jewish War 7.5.5 · Physical: Arch of Titus
What the ancient record says
The spoils were not quietly stored. Josephus describes an enormous victory procession: captives displayed, war scenes represented, spoils carried.
The sanctuary objects were among the most prominent spoils, specifically the golden table, the seven-branched lampstand, and the writings/Turah of the Yahudim. The Turah itself was carried among the spoils.
A Roman triumph was one of Rome's highest victory celebrations, processing captives, representations of conquered lands, and spoils to demonstrate dominance. Corroboration: the Arch of Titus survives in Rome, one relief depicting soldiers carrying a large seven-branched lampstand in the triumph, Josephus's written description + a surviving Roman imperial monument.
Read it for yourself. Josephus, The Jewish War 7.5.5; Arch of Titus, Rome (triumph relief).
Evidence strength: Extremely strong, primary literary (Josephus) + physical monument (Arch of Titus).
