Stator
A Roman surname of Jupiter, describing him as staying the Romans in their flight from an enemy, and generally as preserving the existing order of things. (The History of Rome By Titus Livius)
From Smith's Dictionary of Greek and Roman Biography and MythologyFrom Lives of the Noble Grecians and Romans By Plutarch
They came by break of day, and being denied entrance, made an outcry and disturbance at the gates, which excited all the more suspicion. But Cicero, going forth, summoned the senate into the temple of Jupiter Stator, which stands at the end of the Sacred Street, going up to the Palatine. And when Catiline with others of his party also came, as intending to make his defense, none of the senators would sit by him, but all of them left the bench where he had placed himself. And when he began to speak, they interrupted him with outcries.
From The History of Rome By Titus Livius
The Sabines are in possession of the citadel, purchased by fraud. From thence they are now advancing hither, sword in hand, having already passed the middle of the valley. But do thou, father of gods and men, keep back the enemy at least from hence, dispel the terror of the Romans, and stop their shameful flight. Here I solemnly vow to build a temple to thee as Jupiter Stator, as a monument to posterity, that this city was saved by thy immediate aid.
