Those who actually set out to see the fall of a city or those who choose to go to a front line, are obviously asking themselves to what extent they are cowards. But the tests they set themselves - there is a dead body, can you bear to look at it? - are nothing in comparison with the tests that are sprung on them. It is not the obvious tests that matter (do you go to pieces in a mortar attack?) but the unexpected ones (here is a man on the run, seeking your help - can you face him honestly?).

A glance at the history of European poetry is enough to inform us that rhyme itself is not indispensable. Latin poetry in the classical age had no use for it, and the kind of Latin poetry that does rhyme - as for instance the medieval Carmina Burana - tends to be somewhat crude stuff in comparison with the classical verse that doesn't.

At four lines, with the quatrain, we reach the basic stanza form familiar from a whole range of English poetic practice. This is the length of the ballad stanza, the verse of a hymn, and innumerable other kinds of verse.

I don't see that a single line can constitute a stanza, although it can constitute a whole poem.

Great poetry does not have to be technically intricate.

Writing for the page is only one form of writing for the eye. Wherever solemn inscriptions are put up in public places, there is a sense that the site and the occasion demand a form of writing which goes beyond plain informative prose. Each word is so valued that the letters forming it are seen as objects of solemn beauty.

The basic rhymes in English are masculine, which is to say that the last syllable of the line is stressed: "lane" rhymes with "pain", but it also rhymes with "urbane" since the last syllable of "urbane" is stressed. "Lane" does not rhyme with "methane".
