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 much larger than the tiny tiles used in mosaics, so they can form 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 very special. Even though the name "opus sectile" was given to this style in more recent times, the Romans called it "sectilia pavimenta."

Origin and evolution

Opus sectile began in Rome during the first part of the 1st century BC. It was used for making beautiful floor designs in public buildings under the rule of Augustus. Later, it became popular in private homes, though it was very expensive and mostly found in royal places like the villa of Livia and Tiberius’s homes.

The most famous examples come from 4th-century Rome, like the designs from the Basilica of Junius Bassus. This style spread to places like Constantinople (now Istanbul) and included glass panels showing scenes of famous people and landscapes. It was also used in Byzantine churches and later in places like Sicily and during the Italian Renaissance, where it was used to decorate furniture.
