whose protection they act, and whom the chief fetial (pater patratus) invokes in the rite concluding a treaty. If a declaration of war ensues, the fetial calls upon Jupiter and Quirinus, the heavenly, earthly and chthonic gods as witnesses of any potential violation of the ius. He can then declare war within 33 days. The action of the fetials falls under Jupiter's jurisdiction as the divine defender of good faith. Several emblems of the fetial office pertain to Jupiter. The silex was the stone used for the fetial sacrifice, housed in the Temple of Iuppiter Feretrius, as was their sceptre. Sacred herbs (sagmina), sometimes identified as vervain, had to be taken from the nearby citadel (arx) for their ritual use. Jupiter and religion in the secessions of the plebs The role of Jupiter in the conflict of the orders is a reflection of the religiosity of the Romans. On one side, the patricians were able to naturally claim the support of the supreme god as they held the auspices of the State. On the other side, the plebs (plebeians) argued that, as Jupiter was the source of justice, they had his favor because their cause was just. The first secession was caused by the excessive debt burden on the plebs. The legal institute of the nexum permitted a debtor to become a slave of his creditor. The plebs argued the debts had become unsustainable because of the expenses of the wars wanted by the patricians. As the senate did not accede to the proposal of a total debt remission advanced by dictator and augur Manius Valerius Maximus the plebs retired on the Mount Sacer, a hill located three Roman miles to the North-northeast of Rome, past the Nomentan bridge on river Anio. The place is windy and was usually the site of rites of divination performed by haruspices. The senate in the end sent a delegation composed of ten members with full powers of making a deal with the plebs, of which were part Menenius Agrippa and Manius Valerius. It was Valerius, according to the inscription found at Arezzo in 1688 and written on the order of Augustus as well as other literary sources, that brought the plebs down from the Mount, after the secessionists had consecrated it to Jupiter Territor and built an altar (ara) on its summit. The fear of the wrath of Jupiter was an important element
