There is no fellowship inviolate,
no faith is kept, when kingship is concerned.

[Nulla sancta societas
Nec fides regni est.]

Ennius (239-169 BC) Roman poet, writer [Quintus Ennius]

Quoted in Cicero, De Officiis, Book 1, ch. 8, sec. 26 (scaen. 404 Vahlen), speaking of Julius Caesar.

• "No society is sacred, nor faith of empire." [tr. Johnson (1828)]
• "There is no holy bond, and no fidelity / 'Twixt those who share a throne." [Source]
• "Where the throne's shared, there cannot be good faith." [Source]
