Quinquireme of Nineveh from distant Ophir,
Rowing home to haven in sunny Palestine,.
With a cargo of ivory,
And apes and peacocks,
Sandalwood, cedarwood, and sweet white wine.

When I am asked
how I began writing poems,
I talk about the indifference of nature.

It was soon after my mother died,
a brilliant June day,
everything blooming.

I sat on a gray stone bench
in a lovingly planted garden,
but the day lilies were as deaf
as the ears of drunken sleepers
and the roses curved inward.
Nothing was black of broken
and not a leaf fell
and the sun blared endless commercials
for summer holidays.

BY JOHN KEATS
When I have fears that I may cease to be
Before my pen has gleaned my teeming brain,
Before high-pilèd books, in charactery,
Hold like rich garners the full ripened grain;
When I behold, upon the night’s starred face,
Huge cloudy symbols of a high romance,
And think that I may never live to trace
Their shadows with the magic hand of chance;
And when I feel, fair creature of an hour,
That I shall never look upon thee more,
Never have relish in the faery power

Look at the stars! look, look up at the skies!
O look at all the fire-folk sitting in the air!
The bright boroughs, the circle-citadels there!
Down in dim woods the diamond delves! the elves'-eyes!
The grey lawns cold where gold, where quickgold lies!
Wind-beat whitebeam! airy abeles set on a flare!
Flake-doves sent floating forth at a farmyard scare!
Ah well! it is all a purchase, all is a prize.
