"That's known to the artists who have known,
True gods of sound and stone, and words and tint
I did not stint, for I gave her poems to say"

Which works on the page, but falls apart when sung to that tune in 4/4 times because there's a three beat gap between Stone and And - which makes the next bit a new sentence whether you want it to or not.

Which is exactly the point I was trying to make and is still valid whether you use the "correct" words or the version I posted - which is a common version, as far as I could determine and certainly is the version in the DT database.

The assumption people often make that a tune has to be pretty well exactly the same form verse to verse can make for needless difficulties. It's a nonsense assumption, with no basis in traditional singing in Ireland or for that matter in Britain.

Which is not what I was trying to say but rather that the natural pauses in the words need to fit with the natural pauses in the music. In practice, variation of the tune from verse to verse does not generally change underlying pulse, but more commonly you get notes lengthened or broken into shorter notes to accommodate different numbers of syllables in different verses plus, of course the singer's decoration of the basic melody to give some variation from verse to verse.
