Henry Lawes' Airs and Dialogues, I. 1653.
O, the fickle state of
A heart perplexed with hopes and fears
Today a world of joy discovers,
And tomorrow's drowned in tears:
A lover's state's like April's weather,
Rain and sunshine both together.
If his mistress do but smile,
A heaven of joy is in his heart;
If her brow but frown a while,
Hell can find no greater smart:
In a lover's breast doth dwell
Very heaven, or very hell.
