Analysis of Upon the loss of his mistresses

I have lost, and lately, these
Many dainty mistresses:--
Stately Julia, prime of all;
Sapho next, a principal:
Smooth Anthea, for a skin
White, and heaven-like crystalline:
Sweet Electra, and the choice
Myrha, for the lute and voice.
Next, Corinna, for her wit,
And the graceful use of it;
With Perilla:--All are gone;
Only Herrick's left alone,
For to number sorrow by
Their departures hence, and die.
