Acerenza Cathedral is a Roman Catholic cathedral dedicated to the Assumption of the Blessed Virgin Mary and to Saint Canius in the town of Acerenza. The cathedral is one of the most notable Romanesque structures in this part of Italy.
The diocese was established by the late 5th century, but the structure of the present Romanesque cathedral building dates from 1080, when construction was begun under archbishop Arnald of Cluny. The site however is far more ancient and traces remain in the present building both of a pagan temple to Hercules Acheruntinus and of the earlier Christian church.
It has a Latin cross ground plan, and three aisles, which terminate in a raised presbytery behind which is an apse with an ambulatory and three radiating chapels, an unusual feature in Italian church design; the transept also terminates at either end in a semi-circular chapel. The ambulatory contains the altar which houses the relics of Saint Canius.
The crypt dates from 1524 and contains what is believed to be the sarcophagus of Saint Canius.
The campanile was added in 1555, and reuses many interesting fragments of ancient stonework, including two Roman sarcophagi and a sacrificial altar decorated with bulls' heads.
The interior of the cathedral features many unusual zoomorphic and floral carvings, in the Cluniac manner, the possible symbolic significance of which has caused speculation.
Of especial note are a polyptych showing Our Lady of the Rosary and the Fifteen Mysteries, with Saints Dominic and Thomas, made by Antonio Stabile in 1583, and four frescos in the cloister by Giovanni Todisco di Abriola.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
