ACCI. - Today Guadix, in the province of Granada (Spain), an ancient city, already a Roman colony. From the earliest years of the 4th century it was the seat of a bishopric. Indeed, Felix, the first of the nineteen bishops present at the Council of Illiberis (Elvira, Granada), held around the year 300, was bishop of A. From the signatures of the Toledan councils and from two inscriptions, the names of several bishops of A. are known (late 6th and 7th centuries). Isidore Pacensis preserved the memory of Frodoarius, distinguished for virtue and learning, who governed the see of Acci in the year 719, under the Arabs. More than a century later, Quiricus, the last known bishop of A., attended the Council of Córdoba (839), at which the heresy of the Acephali was condemned. St. Eulogius of Córdoba recounts the martyrdom of the Accitan St. Fandila, which took place in that city on 13 June 853. The see was re-established in the 15th Guadix (v.).
ACCI. - An ancient bishopric on the island of Corsica, located in the canton of La Porta, arrondissement of Bastia. This ancient diocese, whose ruins of the cathedral of St Peter of A. recall its memory, was created in the year 1133, when Pope Innocent II wished to restore peace between the republic of Genoa and that of Pisa (v. *Aiaccio*). In reality, the pope would have erected it in that year following the dismemberment of the dioceses of Aleria and Mariana, not only, according to Rinieri, for an equitable distribution of suffragan sees to one and the other archbishopric, but also in memory of the ancient diocese of Taina or Tavagna, destroyed by the barbarians in the 6th century. In 1563 Pius IV united the bishopric of A. with that of Mariana, to which it remained annexed, as the consistorial archives testify, until the suppression of both dioceses, which occurred following the Napoleonic Concordat of 1801.
