O foolish Physick, and vnfruitfull paine,
2 That heales vp one and makes another wound:
She his hurt thigh to him recur'd againe,
4 But hurt his hart, the which before was sound,
Through an vnwary dart, which did rebound
6 From her faire eyes and gracious countenaunce.
What bootes it him from death to be vnbound,
8 To be captiued in endlesse duraunce
Of sorrow and despaire without aleggeaunce?
