• Parallelogram de Crystalline is an invented verse form with a thematic focus. The subject is a lover and the lover should be described through images of nature. It was introduced by Karan Naidu. The Parallelogram de Crystalline is:
○ a poem in 12 lines, made up of 4 tercets.
○ syllabic 3-6-9 syllables per line for each tercet.
