Coelius Sedulius was a 5th-century Christian poet and priest who lived during the first half of the fifth century. While specific biographical details remain scarce, he is believed to have lived in Italy and may have served as a teacher of rhetoric before dedicating himself to religious literature. His transition toward a more serious Christian life occurred later in his career, and historical records, including the Gelasian decree, identify him as a presbyter.
Literary works

He is primarily recognized for his long poem, Carmen paschale, which interprets the four gospels. This work, written in a style reminiscent of Virgil, became a significant resource for later poets. Additionally, he composed the hymn A solis ortus cardine, which contains verses that were eventually integrated into the Roman Rite liturgy.
Religious legacy
Sedulius is venerated as a saint within the Catholic tradition. His poetic contributions, such as the Christmas carol derived from his Abecedarian hymn, have been translated into numerous languages throughout history. His writings, including the Epiphany hymn and comparisons between the Old and New Testaments, have maintained a presence in Christian liturgical history.
