Sonnet Xvi: In Nature Apt Poem by Sir Philip Sidney

In nature apt to like when I did see
Beauties, which were of many carats fine,
My boiling sprites did thither soon incline,
And, Love, I thought that I was full of thee:

But finding not those restless flames in me,
Which others said did make their souls to pine,
I thought those babes of some pin's hurt did whine,
By my love judging what love's pain might be.

But while I thus with this young lion played,
Mine eyes (shall I say curst or blest?) beheld
Stella; now she is nam'd, need more be said?

In her sight I a lesson new have spell'd,
I now hav learn'd Love right, and learn'd even so,
As who by being poisoned doth poison know.
