The interior decoration of the mansions of Siatista in the 18th and 19th centuries is complemented by carvings in marble or wood, plaster frames, but also by skylights, enriched with decorative motifs and dressed with colored glass. As with other forms of folk art of the Post-Byzantine period, these types of decoration can be found in both religious and secular architecture.
During the Post-Byzantine period, three-dimensional sculptures are rare and eventually get replaced by decorative reliefs. These reliefs adorn fountains and belfries in towns and villages, as well as tombs at the cemeteries, they also frame the doors, windows and skylights in houses and temples, or they are placed inside the buildings to enrich their decoration. In the mansions of Siatista they are found in various parts of the courtyard and the house. On fountains, arbours, inscriptions, fireplaces, sinks and elsewhere. The designs carved by the stone carvers on marble and stone were similar to the designs on other popular creations of the period, namely embroidery, paintings and woodcarvings. Like painting, the sculptures are characterised by spontaneity, simplicity, love of nature and tell their own stories. They are influenced by Byzantine and oriental traditions, beliefs and customs of the locals. They include countless symbols such as crosses, two-headed eagles, saints, human figures, suns, dragons, snakes and flowers. Their purpose was to protect people from spirits and the evil eye, and to drive demons away from the house.
The sculptors belonged to the groups of craftsmen who built and decorated the mansions and traveled together from place to place. They were mainly artisans from Epirus and Macedonia. The marble for their work was either extracted from nearby mines, or taken from older monuments in second-use.
Woodcarving is another art that flourished at that time throughout Greece. Woodcarvings are found in altarpieces, pulpits, chantries and various religious objects in churches and monasteries. The crooks and the flutes used by the shepherds in their everyday life as well as the ships along with their decorative elements, all of them are wood-carved. Last but not least, all the traditional houses and mansions are embellished with wooden elements, which testify the economic and social progress of the upper-class merchants from Siatista during the 18th and 19th centuries.
Carved decorations in the mansions at Siatista include ceilings with elaborate centerpieces, room dividers, gates and doors, closets, cupboards, shelves, icon stands, chests, seats etc.
The bright-colored shapes of the wood carvings, especially the intricate geometric-patterned ceilings, were all influenced by Eastern and Ottoman art. The preparation and processing of the woods were quite demanding and time-consuming procedures, that were committed with patience and hard work. When the woods were ready for use, they were carved by skilled carpenters who were usually members of the craftsmen’s guilds.
The architectural decoration at the mansions was completed with the use of rows of colorful stained glass skylights, placed on the second floor, between the regular windows and the roof. These wall openings, consisting of relief perforated shapes and frames made of plaster, were sealed with colored glasses making the house bright and colorful. The skylights were usually decorated with suns, triangles, circles and rhombuses, plants, trees and birds. Their construction was complex and difficult, and thus required a lot of experience. The style of the skylights was influenced by the European Baroque, which gave great freedom to the imagination and designs of the artists. Over the years, however, they were enriched with themes from local folk tradition.
