“Since ancient times, humans have memorized and recited poetry. Before the invention of writing, the only way to possess a poem was to memorize it. Long after scrolls and folios supplemented our brains, court poets, priests and wandering bards recited poetry in order to entertain and connect with the divine. For individuals, a poem learned by heart could be a lifeline — to grapple with overwhelming emotion or preserve sanity amid the brutalities of prison and warfare.”
