Protesilaus should love!

Originally from Ovid, Heroides 13.84, where Laodamia is writing to her husband Protesilaus who is at the Trojan War. She begs him to stay out of danger, but he was in fact the first Greek to die at Troy. Also used of the Habsburg marriages of 1477 and 1496, written as bella gerant alii, tu felix Austria nube (let others wage war; you, fortunate Austria, marry). Said by King Matthias.
