Classic Poem

If thou be'st ice, I do admire
How thou couldst set my heart on fire;
Or how thy fire could kindle me,
Thou being ice, and not melt thee;
But even my flames, light as thy own,
Have hard'ned thee into a stone!
Wonder of love, that canst fulfil,
Inverting nature thus, thy will;
Making ice one another burn,
Whilst itself doth harder turn!
