FootnotesA similar pattern to the current panel can be seen on the cosmatesques of the Grottaferrata Abbey, near Rome, variously dated between the 1160 and 1282 A.D., which can be a good chronological indicator for our mosaic for style and composition. The Cosmatesque style was a characteristic type of ornamentation of Eastern Roman origin (opus alexandrinum) in the technique of opus sectile (elements already cut with the final shape: circles, squares, triangles and lozenges; small geometric elements which, expertly fitted together, manage to create the effect of a magnificent embroidered carpet) used by marble-makers of the 12th and 13th centuries A.D. The practice of inlaying glass and stone tesserae into white marble panels in this way, although reaching its zenith under the directorship of the Cosmati, had already been established in the Eastern Roman Empire for at least five centuries, and by the 12th century many marble pavements and panels of Opus Alexandrinum had been used to decorate prestigious churches and religious foundations, both across Italy and further afield, often by reusing old Roman monuments.

The Golden Gate, so called in Christian literature, or She'ar Harahamim ('Gate of Mercy') is the oldest of the city gates of the Old City of Jerusalem. It is located on the eastern side of the ancient city walls and it is believed that the meeting at the Golden Gate of Saint Joachim and Saint Anne took place there, an episode depicted in various pictorial cycles dedicated to the life of Saint Anne (including the one by Giotto in the Scrovegni chapel in Padua). The current gate was probably built on the ruins of the older one, in the 6th century A.D., as part of Justinian's building program. According to another theory, the construction took place at the end of the 7th century, by Roman craftsmen hired by the Umayyad caliphs. -
