Shelley, Leigh Hunt, and Keats held a 15-minute sonnet writing contest with the subject restricted to the Nile. This is what one of the master poets could do in his early years with 15 minutes of time. Keats’s sonnet is Petrarchan and wasn’t published until after his death on July 19, 1838.
Shell...
Son of the old moon-mountains African!
Stream of the Pyramid and Crocodile!
We call thee fruitful, and, that very while,
A desert fills our seeing's inward span;
Nurse of swart nations since the world began,
Art thous so fruitful? or dost thou beguile
Such men to honour thee, who, worn with toil,
Rest them a space 'twist Cairo and Decan?
O may dark fancies err!—they surely do;
'Tis ignorance that makes a barren waste
Of all beyond itself. Thou dost bedew
Green rushes like our rivers, and dost taste
The pleasant sun-rise; green isles hast thou too,
And to the sea as happily dost haste.
John-keats released Sonnet.—To The Nile on Wed Feb 04 1818.
