PEITHARKHIA was the spirit (daimona) of obedience to command.
EUPRAXIA (by Soter) (Aeschylus Seven 223)
Aeschylus, Seven Against Thebes 223 ff (trans. Weir Smyth) (Greek tragedy C5th B.C.) :
"When you invoke the gods, do not be ill-advised. For Peitharkhia (Obedience) is the mother of Eupraxia (Success), wife of Soter (Salvation)--as the saying goes.
So she is, but the power of god [Zeus] is supreme, and often in bad times it raises the helpless man out of harsh misery even when stormclouds are lowering over his eyes."
