Sing forth sweete Cherubin (for we have choice
Of reasons in thy beauty and the voyce,
To name thee so, and scarce appeare prophane)
Sing forth, that while the orbs celestiall straine
To eccho thy sweete note, our humane eares
May then receive the Musicke of the Spheares.
But yet take heede, lest if the Swans of Thames,
That adde harmonious pleasure to the streames,
Oth' sudden heare thy well-divided breath,
