You will find this interesting and useful article on the website of the poet Martyn Crucefix. He gives examples of poems under each of the 14 headings. I came across the article just the other week, timely as I’m doing a Poetry School course held at the Manchester Art Gallery.
Martyn has divided these 14 ways into five subgroups:- Through Description, Through Ventriloquism, Through Interrogation, Through Giving an Account and, finally, Come At a Tangent. He suggests people try to write one a day for the next fortnight.
I doubt I’ll manage one a day, but I’ve taken heart from the article: I have lots of abandoned ekphrastic poems, because one tutor was adamant that such poems have no merit if they merely describe!
