The wisest scholar of the wight most wise
By Phoebus' doom, with sugar'd sentence says,
That Virtue, if it once met with our eyes,
Strange flames of love it in our souls would raise;

But for that man with pain his truth descries,
Whiles he each thing in sense's balance weighs,
And so nor will, nor can behold those skies
Which inward sun to heroic mind displays,

Virtue of late with virtuous care to stir
Love of herself, took Stella's shape, that she
To mortal eyes might sweetly shine in her.

It is most true, for since I her did see,
Virtue's great beauty in that face I prove,
And find th'effect, for I do burn in love.

Sir Philip Sidney
