Ovid

“ By a rainstorm, he will tread his way through piled up snows,
When about to press the seas, nor will he plead the swollen Southeast Wind
Nor seek stars suitable for sweeping across the waters.
Who, if neither a soldier nor a lover, will endure the frosts of the night
And snow mixed with dense rain?
One is sent among the hostile foes as a spy,
The other keeps his eye upon his rival, as his enemy. ”

“ It is always the work of a soldier and a wretched lover
Mars is doubtful nor is Venus certain; and the conquered rise again,
And those whom you say never could be brought down, fall.
Therefore whoever called love idleness,
May he stop: love has an active nature. ”

“ Every lover is a soldier, and Cupid has his own camp;
Believe me, Atticus, every lover is a soldier.
The age which is apt for war, is also apt for Love:
Disgraceful [is] an old man as a soldier, disgraceful [is] an elderly lover.
Those spirits which leaders look for in a brave soldier,
A beautiful girl seeks these in a man as her companion:
Both keep watch at night; each rests on the ground;
That one guards the doors of his mistress, that one his general’s.
The duty of the soldier is the long road: send the girl away,
The vigorous lover will follow with boundary removed ”
