Mosaic

Mosaic is a two- or three-dimensional pictorial technique created by arranging small pieces of stone, glass, ceramic, marble, paper, or similar hard materials side by side on a surface to form a pattern or figure. The visual images produced by this technique are also referred to by the same name. The art of mosaic has been widely used throughout history in architectural structures for flooring, wall, and ceiling coverings, serving both aesthetic and functional purposes.

The etymological origin of the word “mosaic” is not definitively known, but it is thought to be connected to the Greek word “mousa” (muse, goddess of inspiration).^【1】  In ancient sources, this art was known as musivum opus and was described in various forms across different languages until the Middle Ages. It was referred to by names such as the Latin tessera, the Italian mosaico, the Persian rize-senk, and the Ottoman Turkish fuseyfisa, before eventually becoming universally known as “mosaic.”^【2】  The art of mosaic has persisted from its earliest applications to the present day, evolving through various techniques and material variations.

Historical Development

The art of mosaic is a decorative and narrative form with origins dating back to ancient times and adopted by diverse cultures. The earliest examples of this art are found in Mesopotamia, specifically in the Al Ubaid and Uruk-Warka (Sumerian) regions, dating to the 4th and 3rd millennia BCE. In these early mosaics, baked clay fragments shaped like cones and resembling nails were placed on wall surfaces with their pointed ends embedded into the structure and their flat surfaces exposed outward. This practice represents the precursor to the concept of wall decoration in mosaic art.

During the Hellenistic period, significant technical and material advancements occurred in mosaic art. The use of glass tesserae began, allowing artists to work with a richer palette of colors thanks to glass’s variety of hues. Mosaics from centers such as Delos, Bergama, Pompeii, and Thmuis are notable examples from this era. In Egypt, at Tel-el-Yedhudia, colored stones and glass fragments were set into ivory panels on column capitals.

During the Roman period, mosaic art reached one of its most advanced stages both technically and aesthetically. Mosaics were widely used on walls, floors, and ceilings. They were not merely decorative but also enriched with narrative elements carrying symbolic meanings that defined the function of the space. Roman mosaics prominently featured geometric patterns, figurative scenes, mythological themes, and depictions of nature.

Various mosaic laying techniques developed since antiquity—such as opus regulatum, opus tessellatum, opus vermiculatum, opus sectile, opus musivum, and opus alexandrinum—increased both the variety of materials and the methods of application. These techniques facilitated the adoption and spread of mosaic art across different cultures.

In the modern era, mosaic continues to exist not only as a legacy of antiquity but also as an integral part of contemporary artistic production. Artists have infused new interpretations into mosaic art by combining traditional techniques with different materials and forms. In this context, mosaic has remained a continuous expressive form both historically and artistically.

Mosaic Techniques

The art of mosaic has been practiced throughout history using various techniques, each developing unique aesthetic and structural characteristics.

• Opus Regulatum: Also known as the “grid pattern,” this technique involves arranging tesserae of equal size in both horizontal and vertical alignments. It is commonly used in the backgrounds and border designs of large-scale mosaics.

• Opus Tessellatum: A laying method resembling brickwork, where each tessera is placed so that its center aligns with the midpoint of the one below. Initially using pebbles, this method later gave way to regularly cut stone, glass, marble, or ceramic tesserae. It was widely applied in Roman times for floor and wall coverings.

• Opus Vermiculatum: Known as the “worm” or “curvilinear” technique, tesserae are arranged along sinuous lines to conform precisely to the contours of the design. It is typically chosen for complex scenes such as human figures and natural landscapes. This technique requires very small tesserae and demands high skill and craftsmanship.

• Opus Sectile: A technique created by placing larger, shaped pieces of stone, marble, or basalt side by side. Figures in the mosaic are usually represented by single or few large fragments. Prominent figures such as humans, birds, or hearts are rendered using this method. Also known as architectural inlay, this technique is suitable for compositions where the central figure is emphasized.

• Opus Musivum: Considered the precursor to wall mosaics, this technique stands out for its ornate and striking decorations. The use of glass tesserae is prevalent in this technique. The reflective quality of glass creates an especially effective visual impact on vaults, domes, and interior walls. This method was frequently used in buildings belonging to the bourgeoisie and in places of worship.

• Opus Alexandrinum: A technique applied to complex compositions with a broad color palette. In addition to marble, precious stones such as cornelian, alabaster, and lapis lazuli were also used. This technique spread from the Mediterranean coasts to Anatolia and the Byzantine regions, then to Rome and Greece. It developed and became widely used during the Byzantine period with the support of the Church.

Applications

The art of mosaic has been applied across various periods and geographies on diverse surfaces for both functional and aesthetic purposes. It is defined as a pictorial narrative technique executed on flat surfaces and has found its place in both interior and exterior spaces.

Since antiquity, mosaics have been widely used on architectural surfaces such as floors, walls, and ceilings. Initially favored primarily for flooring, mosaics began to be applied to vertical surfaces such as walls and vaults as techniques evolved. Floor mosaics were typically made of durable stone, ceramic, or marble tesserae, while wall and vault mosaics favored glass tesserae for their color variety and luminous surface.

The applications of mosaic art were not limited to architecture alone; they were also used on numerous structural elements such as furniture, columns, door thresholds, benches, courtyards, gardens, sculptures, monumental structures, places of worship, public parks, and urban fixtures. Mosaics added both decorative value and narrative elements to these surfaces.

In modern times, the mosaic technique continues to be widely used in disciplines such as painting, sculpture, landscape design, and urban art.

Mosaic Art in Türkiye

The territory of Türkiye contains a broad spectrum of significant examples of mosaic art, from its earliest historical instances to contemporary applications. Mosaic art, developed under the influence of various civilizations since antiquity, has enriched itself within Anatolia’s cultural diversity and is represented by numerous surviving examples.

The earliest known examples of mosaic art in Türkiye trace back to the Sumerian regions of Al Ubaid and Uruk-Warka, influenced by Mesopotamia. In Anatolia, floor mosaics became widespread during the Hellenistic and Roman periods. Mosaics made from natural stone, marble, and pebbles were used as flooring, particularly in Roman cities within public buildings, villas, and bathhouses.

In the modern era, mosaic art in Türkiye regained importance from the mid-20th century onward. Bedri Rahmi Eyüboğlu emerged as a leading representative of contemporary mosaic art. His interest in mosaic began through his involvement in the restoration of the Byzantine mosaics at the Kariye Camii. The artist produced mosaic panels by integrating Anatolian motifs with his own style and carried out various mosaic installations for public buildings.

Eren Eyüboğlu is another artist who contributed significantly to mosaic art in Türkiye. Mosaic panels in institutional buildings such as Etibank, Hacettepe Hospital, Cerrahpaşa Hospital, and Haydarpaşa Chest Diseases Hospital exemplify his work in this field.

In Türkiye, mosaic art maintains its vitality through both ancient examples uncovered in archaeological excavations and contemporary artworks produced by modern artists. Türkiye occupies a significant geographical position in mosaic art, bearing witness to its historical continuity and hosting its current representatives, with rich material diversity.

Notable Mosaics

Due to its history as a homeland to numerous civilizations, Türkiye possesses rich examples of mosaic art in both technical and thematic terms. Mosaics uncovered through archaeological excavations and restoration projects reflect the aesthetic sensibilities and cultural characteristics of different eras.

Iznik Roman Mosaic (Bursa)

The Iznik floor mosaic, dated to the Roman period, was accidentally discovered in 2014 during sewerage works on Afyon Sultan Street in Beyler Mahallesi, Iznik district of Bursa. Upon the discovery of a mosaic depicting a human face, work was halted and the mosaic area placed under protection. After completing necessary expropriations, archaeological excavations were initiated in 2025 under the authority of the Iznik Museum Directorate with permission from the Ministry of Culture and Tourism.

The mosaic uncovered during the excavations spans approximately 400 square meters, with only 50 square meters of the structure so far exposed. The mosaic is believed to belong to either a public building or a villa of a wealthy individual of the period; however, the exact nature of the structure remains undetermined, though a bathhouse is also considered a possibility. The building housing the mosaic was constructed in the 3rd century and destroyed by the end of the 4th century. Subsequent structures were built on this site in later centuries.

The mosaic consists of three main panels, each surrounded by a border of pomegranate and vine leaf motifs. The central panel features a female figure representing Lake Askania—the Roman-era name of Lake Iznik—accompanied by inscriptions. The figure is depicted with hair rendered as aquatic plants, a crown formed of crab claws, and wave motifs around the neck. The side panels depict a goddess of abundance holding a basket and other mythological figures. Additionally, depictions of sandals are interpreted as symbols of entry and exit and are positioned at the center of the mosaic.

The tesserae used in the mosaic are made of stone, marble, and glass, with larger-sized pieces used along the outer edges. Geometric patterns in the mosaic include braided hair motifs and three-dimensional labyrinth-like compositions, with observations indicating the use of three to four different tones of color.

The Iznik Roman Mosaic is regarded as a high-quality work, occupying a prominent place among the original examples of Roman mosaic art in Anatolia in terms of technique, aesthetics, and theme.

Antakya Mosaics

The Antakya mosaics rank among the richest and most original examples of mosaic art from the Roman and Late Antiquity periods. The ancient city known as “Antiocheia” became a major cultural and artistic center between the 2nd and 5th centuries CE, during which mosaic art was intensively used in residential and public buildings.

One of the defining features of the Antakya mosaics is their detailed depictions of mythological scenes, figurative compositions, geometric patterns, and scenes from daily life. The variety of colors and compositional depth in these mosaics reflect the high technical skill of the artists. In these mosaics, dated to the Roman and Late Roman periods, laying techniques such as Opus Tessellatum and Opus Vermiculatum are evident, with small tesserae of stone, glass, or marble arranged systematically to produce intricate figures.

Among the significant mosaics excavated from Antakya and its surroundings are scenes featuring mythological figures such as Dionysus, Orpheus, and Apollo; female figures symbolizing the seasons; and compositions depicting gladiator battles. The majority of these mosaics were uncovered during excavations in the 20th century and are now exhibited at the Hatay Archaeology Museum. The museum is among the world’s most important mosaic collections due to the richness and diversity of its mosaic holdings.

Zeugma Mosaics

The Zeugma mosaics are among the most important examples of mosaic art in Anatolia. Excavated from the ancient city of Zeugma in Gaziantep Province, these mosaics are primarily dated to the Roman period and are found as floor decorations in wealthy residences. The techniques used in these mosaics, particularly Opus Tessellatum and Opus Vermiculatum, enabled detailed figurative renderings with masterful color transitions and shading.

Zeugma mosaics depict mythological scenes, natural landscapes, and elements of daily life. Different materials such as stone, glass, and ceramic were used together in their production, enhancing the richness of the designs and the depth of the compositions. Material selection varied according to the functional characteristics of the areas where the mosaics were installed.

Among the most renowned mosaics from Zeugma are those featuring highly detailed figurative compositions with intense shading techniques. These characteristics demonstrate that the mosaics were not merely decorative but also served as an artistic expression.

Ephesus Mosaics

The Ephesus mosaics hold a significant place among the decorative examples found on the floors and walls of residential, public, and religious structures within the Roman-era urban fabric. These mosaics were primarily used as floor coverings and displayed a wide visual variety ranging from geometric patterns to figurative depictions.

Among the prominent areas where Ephesus mosaics were applied are the floors of luxury private rooms. These mosaics, laid using techniques such as Opus Tessellatum and Opus Sectile, feature central panels surrounded by symmetrical geometric designs, depicting mythological figures, animal representations, and stylized natural elements. Materials used for the tesserae included stone, marble, and glass.

The mosaic examples found in Ephesus do not serve only an aesthetic function; they also provide archaeological clues regarding the temporal use of the structures. Particularly, inscribed mosaics in specific areas offer grounds for archaeological interpretations concerning the social status or ownership of the buildings.

Istanbul Mosaics (Great Palace Mosaics)

The Great Palace Mosaics in Istanbul are among the most prominent examples of floor decorations from Byzantine-era palaces. These mosaics, belonging to the early Byzantine Great Palace Complex, are notable for their visual richness and craftsmanship.

The techniques used in the Great Palace Mosaics include Opus Tessellatum and Opus Vermiculatum. These techniques enabled the creation of detailed patterns and figurative compositions with a three-dimensional effect. The tesserae used were made of stone, glass, and ceramic, with glass tesserae particularly facilitating rich color transitions.

The mosaics feature central panels depicting scenes of daily life, animal figures, and natural imagery. Compositions frequently include animals such as lions, tigers, and elephants, along with hunting scenes, all framed by borders to create a cohesive design.

The Great Palace Mosaics were not merely decorative; they also functioned as a social and cultural narrative tool within Byzantine palace architecture. The anatomical accuracy of the figures and the detailed rendering of natural elements reflect the artistic achievements of the period.

The Istanbul Great Palace Mosaics are regarded as a significant example documenting the Byzantine understanding of mosaic art and preserving the visual traces of Byzantine palace culture.

Notable Examples Worldwide

Throughout history, mosaic art has developed across various regions using diverse techniques and materials, producing significant masterpieces. Globally renowned mosaic examples are notable not only artistically but also culturally and technically.

Delos Mosaics

The Delos mosaics are among the leading examples of Hellenistic mosaic art. Delos, one of the Cycladic Islands of Greece, gained importance in antiquity as a religious and commercial center. The wealthy residences and public buildings constructed on the island during this period were adorned with floor mosaics reflecting the development of mosaic art.

The mosaics of Delos embody the characteristic features of the Hellenistic period both technically and aesthetically. Techniques such as Opus Tessellatum and Opus Vermiculatum were employed to achieve detail and depth in figurative depictions. Common motifs include mythological figures, animal scenes, sea creatures, and geometric patterns. Compositions are typically symmetrical and framed by borders.

The Delos mosaics are also notable for being among the earliest examples to incorporate glass tesserae. The introduction of glass enriched the color palette and provided artists with a broader expressive range. This innovation contributed significantly to the technical and visual evolution of mosaic art in subsequent periods.

Pompeii Mosaics

The Pompeii mosaics are among the most important ancient examples reflecting daily life, aesthetic sensibilities, and technical skill in the Roman Empire. Archaeological excavations in the city of Pompeii, buried under lava and ash following the eruption of Mount Vesuvius in 79 CE, have uncovered numerous well-preserved examples of Roman mosaic art.

Pompeian mosaics are generally found on the floors and walls of residences. Wealthy homes featured mosaics in entrance halls, atriums, peristyles, and tricliniums—dining rooms. These mosaics depict mythological scenes, sea creatures, animal representations, battle and hunting scenes, scenes from daily life, and inscriptions. Techniques such as Opus Tessellatum, Opus Vermiculatum, and Opus Sectile enabled both figurative and geometric compositions.

A distinctive technical feature of Pompeii mosaics is the use of extremely small tesserae to create detailed depictions. Particularly in famous examples such as the Temple of Isis and the Alexander Mosaic, tonal gradations, light and shadow transitions, and three-dimensional effects are striking.

Thmuis Mosaics

The Thmuis mosaics encompass mosaic examples found in Thmuis, an important city in the Nile Delta region of ancient Egypt during the Roman period. These mosaics stand out for their iconography and technical practices that combine Hellenistic and Roman influences.

The widespread use of glass in Thmuis mosaics marks a turning point in Hellenistic mosaic art. Glass enabled the creation of a wide range of colors, expanding the artists’ palette. This technical advancement enhanced both the visual diversity and aesthetic depth of the mosaics in Thmuis.

The mosaic examples from the region were primarily used for floor coverings, with greater emphasis placed on decorative and geometric patterns rather than figurative scenes. Mythological motifs and symbolic figures also appear in places on the mosaic surfaces.

The Thmuis mosaics successfully created varied surface effects by combining glass tesserae with stone and ceramic materials. In this regard, Thmuis is regarded as one of the centers reflecting a synthesis of Roman and Hellenistic mosaic art in terms of material diversity and motif usage.

Tel-el-Yedhudia Mosaics

The Tel-el-Yedhudia mosaics are early examples of mosaic art found in the Tel-el-Yedhudia region of ancient Egypt. These mosaics are particularly notable in terms of architectural decoration traditions. In the decoration of column capitals in the area, small stones, lapis lazuli, and miniature glass fragments were set into ivory panels.

The materials used in these mosaics provided color richness and established a lavish decorative style reflecting the artistic tastes of the period. The Tel-el-Yedhudia examples are significant because they were applied to architectural elements rather than to walls or floors.

The use of glass and semi-precious stones in these mosaics is interpreted as a manifestation of the material diversity that began in the Hellenistic period and extended into Egypt.
