It’s amazing how many forms of poetry have been invented. No doubt there are many others in addition to those you mentioned.
No doubt, indeed. I haven’t even scratched the surface of what’s out there Bob.
I was just reading something else when I noticed this link and had to come and investigate. I have made an attempt or two at Lukes Octains, but thats it from this list. Now I guess I am just going to have to try some of the others out, just to satisfy my own curiosity.
