Analysis of On The Death Of William Cartwright

I cannot keep my purpose, but must give
Sorrow and Verse their way; nor will I grieve
Longer in silence; no, that poor, poor part
Of natures legacy, Verse void of Art,
And undissembled teares, CARTWRIGHT shall have
Fixt on his Hearse; and wept into his grave.
Muses I need you not; for, Grief and I
Can in your absence weave an Elegy:
Which we will do; and often inter-weave
Sad Looks, and Sighs; the ground-work must receive
Such Characters, or be adjudg'd unfit
For my Friends shroud; others have shew'd their Wit,
Learning, and Language fitly; for these be
Debts due to his great Merits: but for me,
My aymes are like my self, humble and low,
Too mean to speak his praise, too mean to show
The World what it hath lost in losing thee,
Whose Words and Deeds were perfect Harmony.
But now 'tis lost; lost in the silent Grave,
Lost to us Mortals, lost, 'till we shall have
Admission to that Kingdom, where He sings
Harmonious Anthems to the King of Kings.
Sing on blest Soul! be as thou wast below,
A more than common instrument to show
Thy Makers praise; sing on, whilst I lament
Thy loss, and court a holy discontent,
With such pure thoughts as thine, to dwell with me,
Then I may hope to live, and dye like thee,
To live belov'd, dye mourn'd, thus in my grave;
Blessings that Kings have wish'd, but cannot have.
