Againe of the Nightingale

WHat (Philomela) meanes this fond intent
To hatch thy broode in fell Medaeas lap?
What? doste thou hope hir rigor will relent
Towarde thy Babes, that gaue hir owne no pap?
But slue them all at once, and at a clap?
I wote not what thou meanste: vnlesse that shée
Should kill thy Brats, too make the Mother frée.
