Such sisters I see out this divine world!
Attached at the hip but one envious.
Young Sea reflects the elder Sky in vain,
But shifting surface leaves Her unfulfilled.

Old Sky doth hold the heavens and pale Moon.
By day, She colors fire of burning Sun.
The ocean doth not give a man his breath.
He toils hard to keep adrift on Sea.

Yet what is Sky's beauty to Sea's compared?
The ocean runs deep and hides mysteries.
Is Sky as generous to share with Man?
Of treasures, Sea rewards to seekers brave.

No, young capricious Sea! 'Tis You the one
Who outpaces Old Sky's bland indiff'rence.

Blank verse, iambic pentameter sonnet. Not traditional Shakespeare, but since when were Roger's poems ever traditional? :D
