Micheal, thank you for your welcome contribution. Could you do me a favour and check whether the version printed in your Collected Poems does in fact have a full stop (period) between "tint" and I " in the couplet

"To the artists who have known the true gods of sound and stone
And word and tint. I did not stint for I gave her poems to say."

as MCP's version above states.

I am not being pedantic here, the presence or absence of the period alters the meaning of the whole verse.
