Eustasio di Napoli was an early Christian bishop of Naples who served during the second or third century. Historical records, including medieval texts from the ninth and tenth centuries, identify him as the seventh bishop of the city. He succeeded Saint Agrippin and preceded Ephebus in the episcopal succession. Although specific biographical details are scarce, he is recognized as a significant figure in the early history of the Neapolitan church.
Historical accounts
Medieval documents, such as the Catalog of Neapolitan Bishops, suggest his tenure lasted seventeen years. This period is estimated to have coincided with the papacies of Anterus and Fabian. These records place his leadership well before the documented era of Bishop Fortunatus in the mid-fourth century, establishing his position within the early ecclesiastical hierarchy of Naples.
Veneration and relics
The remains of the saint were reportedly moved during the ninth century to the main altar of the church known as Santa Maria in Cosmedin. His status as a saint was formally confirmed by Pope Leo XIII in 1884. He is commemorated in both Catholic and Orthodox traditions, with his feast day observed on March 29.
