Where is this from?

It's from the 15th stanza of Browning's poem "Childe Roland to the Dark Tower Came" (google it for the whole poem):

"I shut my eyes and turned them on my heart.
As a man calls for wine before he fights,
I asked one draught of earlier, happier sights,
Ere fitly I could hope to play my part.
Think first, fight afterwards - this soldier's art:
One taste of the old time sets all to rights."

diagknowz--

Thanks after the fact too.

could anybody fill in the blanks in this quote for me..........

"what a wicked web we weave when we *something something* we try to decieve"

That is a quote (misquoted) from Walter Scott's poem Marmion:

Oh what a tangled web we weave,
When first we practise to deceive!

And thank you, i think i'll change my signature line to another Walter Scott quote which i like . . .
