Only Four Popes Did Poetry

That is Before John Paul II, only three pontiffs did poetry: Saint Damasus I, Pius II and Leo XIII.

.He wrote and published poetry in Latin from his youth up to the last months of his life...Leo XIII (Pope from 1878 to 1903) was actually a contributor to the arts journal Arcadia under the name Neandro Ecateo. .

They don't talk about Pope Saint Damasus but the Roman Martyrology is based on the fourth-century poem of Pope St. Damasus.

See From Saint Damasus to Blessed Wojtyla, the stories of the poet popes.
