Where Will You Find The Stained Glass Windows In Milan Duomo

The stained glass windows of the Duomo di Milano are spread throughout the cathedral, adorning various sections. As sunlight streams through the windows, it creates colorful patterns on the floor. Following these light displays can lead you to the windows themselves.
However, there are innumerable places inside the cathedral where you will find these windows; here are a few areas where you will find them for sure:
- Main Nave and Apse: Many of the larger and more impressive windows are located in the Duomo’s main nave (central corridor) and apse (rounded eastern end). These windows often depict grand scenes from the Bible.
- Transepts: The transepts (arms extending from the central nave) also feature stained glass windows, though they may be smaller than those in the nave and apse. They might showcase depictions of saints or specific stories.
- Baptistery: The Baptistery, a separate area within the Duomo dedicated to baptisms, is known for its large stained glass windows, some portraying scenes from the Old and New Testaments. It might seem obvious, but don’t forget to gaze upwards! The stained glass windows are high on the walls and ceilings.
If you’re unsure where to find specific windows, consider asking a tour guide or the staff for assistance.
Design and Styles of the Stained Glass Windows
The stained glass windows were designed to complement the Gothic architecture of the Duomo. The scale, color palette, and thematic elements were carefully chosen to create a unified and awe-inspiring experience for visitors. Beyond the main figures, the windows often include intricate details that add to the narrative.
These details could include depictions of landscapes, flora and fauna, or even architectural elements that provide context to the stories being told. They serve not only as beautiful works of art but also as a window into the religious beliefs and artistic styles that prevailed over centuries.
Religious Themes:
- A significant portion of the windows depict scenes from the Old and New Testaments. These visual stories served as a “Bible for the Poor,” allowing even illiterate viewers to understand biblical narratives. Popular themes include the life of Christ, stories of Moses and the Exodus, and scenes from the Book of Revelation.
- Many windows showcase revered saints and martyrs, often identified by their symbols or attributes. These figures served as inspirational role models and protectors for the faithful.
Artistic Styles:
Styles of these stained windows evolved continuously and reflected ideologies of different periods.
- The earliest windows (late 14th century) exhibit characteristics of the Gothic style – rich color palettes, intricate figural representations, and a focus on light and shadow for dramatic effect.
- As the project progressed into the 15th and 16th centuries, Renaissance elements emerged.
These windows often featured more realistic portrayals of figures, balanced compositions, and classical architectural motifs incorporated into the designs. - Windows from the 17th to 20th centuries showcase a more comprehensive range of styles.
Some might retain religious themes with more Baroque flourishes, while others might reflect Mannerist or even modern artistic influences.
Glasswork Technique on Duomo di Milano Stained Glass Windows
Creating these windows wasn’t simple. They are the result of several key techniques employed by skilled glassworkers.
- Glassblowing and Staining: Molten glass is blown into sheets and then stained with metallic salts or compounds to achieve a vast array of vibrant colors.
- Enameling: Opaque and translucent enamels are painted onto the glass surface, allowing for finer details and highlights.
- Leading: Combining individual glass pieces using lead cams creates a robust, weatherproof framework.
The artists also masterfully manipulated light and shadow to create depth, drama, and a sense of awe within the cathedral. The colors come alive as sunlight streams through the windows, illuminating the vast interior space.
