The name gained renewed visibility through St. Alphonsus Maria de Liguori (1696–1787), founder of the Redemptorists, which encouraged its use in Catholic countries and diaspora communities; another Jesuit saint, Alphonsus Rodríguez, further anchored it in hagiography. The lunar crater Alphonsus commemorates Alfonso X “the Wise,” reflecting the historic Latin spelling.
