Opus Regulatum
''Opus regulatum'' is the Latin name for the normal technique of Greek and Roman mosaic, made from tesserae that are larger than about 4 mm. Tesserae are laid in a pattern like grid or graph paper. The grout lines are aligned both vertically and horizontally unlike '' opus tessellatum'', which consists of either horizontally or vertically aligned tesserae. It is useful in creating geometric patterns or for a background.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...

Mosaic
A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world. Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms. Mosaics have a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from the 6th to the 15th centuries; that tradition was adopted by the Norman Kingdom of Sicily in the 12th century, by the eastern-influenced Republic of Venice, and among the Rus. Mosaic fell ou ...

Tesserae
A tessera (plural: tesserae, diminutive ''tessella'') is an individual tile, usually formed in the shape of a square, used in creating a mosaic. It is also known as an abaciscus or abaculus. Historical tesserae The oldest known tesserae date to the 3rd millennium BC, discovered in the ancient city of Shahdad in Kerman province, Iran. In early antiquity, mosaics were formed from naturally formed colored pebbles. By roughly 200 BC cut stone tesserae were being used in Hellenistic- Greek mosaics. For instance, a large body of surviving material from the Hellenistic period can be found in the mosaics of Delos, Greece, dating to the late 2nd century BC. Ancient Roman decorative mosaic panels and floor mosaics were also produced during the 2nd century BC, particularly at sites such as Pompeii. Marble or limestone were cut into small cubes and arranged into representational designs and geometric patterns. Later, tesserae were made from colored glass, or clear glass backed w ...

Opus Tessellatum
''Opus tessellatum'' is the Latin name for the normal technique of Greek and Roman mosaic, made from tesserae that are larger than about 4 mm. It is distinguished from the finer ''opus vermiculatum'' which used tiny ''tesserae'', typically cubes of 4 millimetres or less, and was produced in workshops in relatively small panels which were transported to the site glued to some temporary support. ''Opus tessellatum'' was used for larger areas and laid down at the final site. The two techniques were often combined, with small panels of ''opus vermiculatum'' called ''emblemata'' at the centre of a larger design in ''opus tessellatum''. The tiny ''tesserae'' of ''opus vermiculatum'' allowed very fine detail, and an approach to the illusionism of painting. There was a distinct native Italian style of ''opus tessellatum'' using only black on a white background, which was no doubt cheaper than fully coloured work. ''Opus tessellatum'' is usually used for backgrounds consisting of horizo ...

Opus Sectile
''Opus sectile'' is a form of pietra dura popularized in the ancient and medieval Roman world where materials were cut and inlaid into walls and floors to make a picture or pattern. Common materials were marble, mother of pearl, and glass. The materials were cut in thin pieces, polished, then trimmed further according to a chosen pattern. Unlike tessellated mosaic techniques, where the placement of very small uniformly sized pieces forms a picture, ''opus sectile'' pieces are much larger and can be shaped to define large parts of the design. Origin and evolution Early examples Early examples have been found from Egypt and Asia Minor. The Herodian Temple in Jerusalem was built during the second half of the 1st century BCE and the first half of the 1st century CE. Recent work by the Temple Mount Sifting Project has recovered enough pieces of polished stone triangles and squares from the Herodian Temple Mount to reconstruct geometric patterns of ''opus sectile'' flooring.

Opus Vermiculatum
''Opus vermiculatum'' is a method of laying mosaic tesserae to emphasise an outline around a subject. This can be of one or more rows and may also provide background contrast, e.g. as a shadow, sometimes with ''opus tessellatum''. The outline created is often light and offset by a dark background for greater contrast. The name ''opus vermiculatum'' literally means "worm-like work", and has been described as one of the most demanding and elaborate forms of mosaic work. Usually ''opus vermiculatum'' is meant to put emphasis on the main design and foreground details of a work, using a smooth and flowing halo-effect. Sometimes it was used only around the head of a figure. The tesserae used were often square but can be variously shaped.Strong, Donald (June 1, 1992). ''Roman Art: The Yale University Press Pelican History of Art''. Yale University Press. . p. 56 History ''Opus vermiculatum'' originated in Greece, later than other mosaic methods. The earliest known example is the So ...
