The Exponent of Blue

... Blue! ‘Tis the life of waters -- ocean
And all its vassal streams, pools numberless,
May rage, and foam, and fret, but never can
Subside if not to dark blue nativeness.

... What strange powers
Hast thou, as a mere shadow! But how great,
When in an eye thou art, with fate!

-- John Keasts, from “Blue! ‘Tis the life of heaven, this domain”
