Two 16-line poems that are easy to memorize are "Lean out of the Window" by James Joyce and "A Poison Tree" by William Blake. Both of these brief narrative poems contain frequent repetition and simple rhyme schemes that make them easy to commit to memory.
"Lean out of the Window" is a short poem by Irish novelist and poet James Joyce. It contains four stanzas of four lines each that ask an unnamed subject to lean out of the window so that the narrator can observe her golden hair. James Joyce published multiple works during the 19th and 20th centuries. He was most famous for his sprawling novel "Ulysses," an epic work with a stream of consciousness narrative that established him as one of the most prominent writers of the modern literary movement.
"A Poison Tree" is a 16-line poem by English poet and painter William Blake. The poem tells a morbid story of anger, deceit and betrayal. William Blake published many poems between the 18th and 19th centuries, and he was known for the philosophical and mystical nature of much of his work. Although Blake received little recognition from many of his contemporaries, his work acquired a large amount of attention a century after his death, and many scholars began to call him a luminary of the Pre-Romantic era.
