San Domenico Maggiore is a Gothic, Roman Catholic church and monastery, founded by the friars of the Dominican Order, and located in the square of the same name in the historic center of Naples.

The square is bordered by a street/alleyway popularly called "Spaccanapoli" (presently labeled via Benedetto Croce at this particular section of its considerable length) in the historic center of Naples.

Sacristan Domenic of Caserta claimed to have seen Aquinas levitating in prayer with tears before an icon of the crucified Christ in the Chapel of Saint Nicholas after Matins on December 6, 1273.

The decorations of the wardrobes doors, realized by Francesco Antonio Picchiatti, embrace the same style as the terracotta tiled floor by Donato and Giuseppe Massa, who have also worked for the Santa Chiara cloister in Naples.

On this one, still today, the signs of the fire that burnt up the church in 1506 are visible; the ochre damask dress of Isabella Sforza of Aragon, with squared neckline and long silk ribbons to keep together the sleeves with the bodice.

The second part, situated on the north-west wall, is characterized by some Dominican saints busts in papier-mâché, wooden and silver lamina, which were carried in triumph during the religious processions in the 18th and 19th centuries.

In the central wardrobes there are two refined flax drapes embroidered in silk and gold, part of a collection dedicated to the "history and virtues" of Saint Thomas Aquinas, donated to the Dominicans by his descendant Maria d’Aquino in 1799.

The third section conserves the most precious liturgical vestments owned by Dominican friars, an awesome collection of copes and chasubles in multicolour silks, silver and gold linens, '700 century[clarification needed] altar frontals, mother-of-pearl ornaments, reliquary, monstrances and candelabra.

[2][3][4][5][6][7] The Treasure Room of San Domenico Maggiore houses a tapestry depicting the Chariot of the Sun, part of the Stories and Virtues of St Thomas Aquinas, donated to the Dominicans by Vincenza Maria d'Aquino Pico[8] The fourth and last section shows the objects which adorned the sacred places of the basilica in the past.

Pieces of great visual suggestion are the two busts from the 18th century: one of Pope Pius V, promoter of the famous battle of Lepanto in 1571, and one of St. Dominic, founder of the Dominican order, represented according with the typical iconography: a star on his head, a dog running with a torch in his mouth, and a church.

Therefore, even in the "textile art" sector, Naples conserved its status of "Refined City" for a long time, and the Treasure Chamber proves this record beyond doubt.
