Mille Regretz by Josquin des Prez
Mille regretz de vous abandonner
Et d'eslonger vostre fache amoureuse,
Jay si grand dueil et paine douloureuse,
Quon me verra brief mes jours definer.
Translation:
A thousand regrets at deserting you
and leaving behind your loving face,
I feel so much sadness and such painful distress,
that it seems to me my days will soon dwindle away.
