Opus sectile

Opus sectile is a beautiful way of decorating walls and floors that was popular in ancient and medieval times, especially in the Roman world. It involves cutting special materials like marble, mother of pearl, and glass into thin, pretty shapes and then placing them into patterns or pictures on surfaces. These pieces are larger than the tiny tiles used in mosaics, so they can create bigger parts of the design.

People would carefully cut the materials, polish them, and then trim them to fit the chosen pattern. This art form lets artists create large, colorful designs that can make a room feel special. Even though the name "opus sectile" was given to this style later, the Romans called it "sectilia pavimenta."

Origin and evolution

Opus sectile started in Rome in the early 1st century BC. It was used to make pretty floor designs in big public buildings when Augustus was in charge. Later, it became popular in private homes, but it was very costly and mostly seen in royal places like the villa of Livia and Tiberius’s homes.

The best-known examples are from 4th-century Rome, such as the designs from the Basilica of Junius Bassus. This style traveled to places like Constantinople (now Istanbul) and included glass panels with pictures of important people and scenery. It was also used in Byzantine churches and later in areas like Sicily and during the Italian Renaissance, where it decorated furniture.
