ITALO-BYZANTINE RITE. – It may be divided into two branches, the Italo-Greek and the Italo-Albanian. The first designation refers to that rite introduced or renewed in Sicily and southern Italy with the arrival in the 7th century of many exiles from the Near East, who had fled before the Arabs, or rather with the establishment of Byzantine imperial rule in these regions. It experienced its finest flowering from the 9th to the 12th century; among the many liturgical poets, it is sufficient to name St. Giuseppe l’Innografo. The presence of the liturgies of St. James, St. Mark, and St. Peter, as well as that of its own Typicon, proves that the rite of

The peculiarities of this rite, which has not yet been sufficiently studied, are recorded in numerous codices preserved in the libraries of Grottaferrata, the Vatican, and Messina; then, for the period of its decline, in the books printed at Rome or Grottaferrata: the three Liturgie (1601), the Liturgicon (similar to the Latins’ plenary Missal; 1683), the Orologion (1677 and 1772), the Salterio (1685), the small Euchologion (1831), and, after the renewal, the Orologion (1950). The Office indicates a type distinctly more ancient than that of the Byzantine rite of today.
The italo-albanese became the rite of the regions of Calabria and Sicily when the refugees from Albania mingled with the few faithful who still practiced the Byzantine rite there, that is, after the 15th century. The liturgical language did not change, because in Albania itself only Greek was in use; new melodies probably arose in liturgical singing, and these are still preserved (cf. F. Falsone, I canti ecclesiastici greco-siculi, Padua 1936, lithograph). Gregory XIII (1573), Clement VIII (1595), and Benedict XIV (1742) issued various instructions to regulate the rite. The three Liturgie had been printed at Rome in 1526, and in 1598 a kind of Breviary called Anthologion, compiled by Antonio Arcudio, was published.
When the Holy See established a commission for the edition of the liturgical books of the Eastern Churches, the Triodion appeared in 1724, with the deliberately false indication of Bologna; A. Arcudio’s Anthologion was reprinted in 9 volumes in 1738, and the Euchologion appeared in 1754; on this occasion Benedict XIV issued the bull Ex quo primum (1 April 1756), in which he gives the history of this edition and explains at length certain ritual observances proper to the Eastern Churches. Then, from 1873 to 1902, all the liturgical books of the Byzantine rite, with the exception of the Typicon, were printed in 16 volumes; the edition of the Orologion was resumed in 1937, and an Archieraticon and an Aghiasmatarion are in preparation. From all these books it is evident that the Italo-Albanian rite differs in no way, as regards texts and rubrics, from that used at Constantinople or in Greece.
