Two Gentlemen of Verona (Proteus)

Proteus says

Say that upon the altar of her beauty
You sacrifice your tears, your sighs, your heart:
Write till your ink be dry, and with your tears
Moist it again, and frame some feeling line
That may discover such integrity:
For Orpheus’ lute was strung with poets’ sinews,
Whose golden touch could soften steel and stones,
Make tigers tame and huge leviathans
Forsake unsounded deeps to dance on sands.
After your dire-lamenting elegies,
Visit night your lady’s chamber-window
With some sweet concert; to their instruments
Tune a deploring dump: the night’s dead silence
Will well become such sweet-complaining grievance.
This, or else nothing, will inherit her.
