As someone who is studying for an MFA in Creative Writing at Lesley University in Cambridge MA, I find myself reading a lot of poetry these days. I thought I would include this short pithy one below, as it gives a perfect definition of an epigram. The photo is of Samuel Taylor Coleridge:
What is an Epigram? A dwarfish whole;
Its body brevity, and wit its soul.
–Samuel Taylor Coleridge (1772-1834)
