The
sodalitas dispatched two of its members, of whom only one, called the
pater patratus, was active, while the other, called
verbenarius, was limited in function to accompanying the
pater patratus with sacred herbs (
sagmina of vervain) gathered on the
Capitolium. We know the ceremonies and formulae of two circumstances: (1) conclusion of a treaty and (2) request of reparations and declaration of war. In the first circumstance the
pater patratus called bystanders and the gods to witness, staked the word of Rome, and vowed Rome to divine wrath if it should not abide by its word, asking for
execratio. Oaths were made by
Jupiter Lapis (
per Iovem Lapidem). The flintstone was believed to be a seat of Jupiter's because if struck it emitted sparks, thus being analogous to lightning. The ceremony has two known variants. In the first one the
pater patratus hits a pig with flintstone taken from the temple of
Jupiter Feretrius pronouncing the
formula referred by Livy; in the second he throws the flintstone and vows Rome to fall as the stone itself if it should fail to abide by the oath. When Rome asked for reparations for an offense or damage, the fetials were sent as ambassadors to the foreign country concerned. If the requests borne by the
pater patratus were not met, he went back to Rome after invoking Jupiter, Juno (or Janus), and Quirinus, along with the heavenly gods, the terrestrial gods, and the gods of the netherworld as witnesses of the violation of the
ius and after declaring war within 30 or 33 days. When this period of time had expired he went back to the border and opened the hostilities with a magic gesture: while affirming once again the good right of Rome he threw a spear with steel point or a javelin of
corniolum hardened with fire into the enemy's territory. The fetials were a common institution of the Latins and of other Italic people. According to G. Dumézil, the initial contract concluded with the gods and extended through the
sacra and the
signa is sufficient to justify the acts of official religious authorities (such as pontiffs and augurs) within the Roman
ager. Actions beyond this boundary require an additional religious foundation, based not only on
ius but also, on a deeper level, the
fas on which
ius is based. This is the task of the fetials who achieve their aim through the *
feti-, word that as Vedic
dhātu means
founding. They rely on a set of ceremonies that bestow a religious value on the political or military decisions of the magistrates, ensuring that under any circumstance Rome has the gods on her side. Besides offering their advice on international issues to the senate or the consuls, the
sodalitas dispatches two envoys (the
pater patratus and the
verbenarius, the last one having only the task of carrying the
sagmina taken from the Capitol Hill) to ask for the reparations, to declare war in a form that is pious and just, and lastly to conclude the peace. The god under whose protection they act and whom the
pater patratus invokes is
Iupiter Lapis in the rite of the conclusion of a treaty and in general when there an agreement is reached. If a declaration of war ensues the fetial calls as witnesses Jupiter, Juno (or Janus, correction accepted by most editors), Quirinus, the heavenly, earthly and nether gods of the violation of the
ius and declares war within thirty-three days. ==Political implications of the
