Poem by Mike Wilson, photo by Jevardh (Unsplash) A gigan is an invented form. Invented forms have become fashionable in poetry. The gigan was invented by poet Ruth Ellen Kocher and is named after a monster in Godzilla.The rules of the form are: 1. The poem is 16 lines. 2. The lines are broken into couplet, tercet, couplet, couplet, couplet, tercet, couplet. 3. Line 1 is repeated as line 11. 4. Line 6 is repeated as line 12. 5. The closing couplet puts a twist on the poem.
