Roman mosaics are constructed from geometrical blocks called tesserae, placed together to create the shapes of figures, motifs and patterns. Mosaic decoration was not just confined to floors but featured on walls and vaults as well.

The oldest mosaic art has been traced back to a Mesopotamian temple that existed during the third millennium B.C. This art was made with stones, seashells, and ivory. Ancient Greek artists used small pebbles to make their mosaics. Greeks were also instrumental in developing mosaic art into complex patterns.

Mosaic (adj.) “pertaining to Moses,” 1660s (earlier Mosaical, 1560s), from Modern Latin Mosaicus, from Late Latin Moses (see Moses).

The Romans perfected mosaics as an art form. The Greeks refined the art of figural mosaics by embedding pebbles in mortar. The Romans took the art form to the next level by using tesserae (cubes of stone, ceramic, or glass) to form intricate, colorful designs.

The earliest decorated mosaics in the Greco-Roman world were made in Greece in the late 5th century BCE, using black and white pebbles. Mosaics made with cut cubes (tesserae) of stone, ceramic, or glass were probably developed in the 3rd century BCE, and soon became standard.

A mosaic is a piece of art created by assembling small pieces of colored glass, ceramic, stone, or other materials into an image. Roman mosaics appeared on floors in houses as early as the 2nd century BCE. Romans used mosaics to decorate floors and walls in homes and temples.

In Rome, Nero and his architects used mosaics to cover some surfaces of walls and ceilings in the Domus Aurea, built 64 AD, and wall mosaics are also found at Pompeii and neighbouring sites. However it seems that it was not until the Christian era that figural wall mosaics became a major form of artistic expression.

The second dispensation of Bible history is commonly called the “Mosaic Period.” An understanding of this period is important for it is the history of the fulfillment of God’s promises to Abraham-that through Abraham’s seed God would bless all families of the earth (Gen. 12:1-3).

mosaic, in art, decoration of a surface with designs made up of closely set, usually variously coloured, small pieces of material such as stone, mineral, glass, tile, or shell. Mosaic also differs from inlay in the size of its components.

A mosaic is an artistic technique that uses tiny parts to create a whole image or object. Mosaics are usually assembled using small tiles that are made of glass, stone, or other materials. Typically the tiles are square, but they can also be round or randomly shaped.

Mosaicism is when a person has 2 or more genetically different sets of cells in their body. Chromosomes are stick-shaped structures in the middle of each cell in the body. Each cell has 46 chromosomes grouped in 23 pairs. A person with mosaicism may have some cells in their body with 46 chromosomes.

The definition of a mosaic is artwork made by placing colored pieces such as stone, glass or tile into a design and then setting the design in mortar. An example of a mosaic is the dragon at the entrance of Antoni Gaudi’s Park Güell in Barcelona, Spain. An individual exhibiting mosaicism.

Embryos that are mosaic can have different proportions of normal and abnormal cells. A low-level mosaic embryo would have mostly normal cells and a lower percentage of abnormal cells. A high-level mosaic embryo would have mostly abnormal cells and a lower percentage of normal cells.

Mosaic embryos should only be used if there are no normal embryos available (or another IVF cycle is not possible).

In all, mosaic embryos, especially low level mosaics, can result in a normal healthy pregnancy and so could be considered to transfer if that is all that one has to transfer.

Mosaic embryos have the potential to implant and develop into healthy babies. From centers worldwide, there is an increasing number of reports of live births following the transfer of mosaic embryos (Greco et al.

If fewer than 20 percent of the cells in the blastocyst are abnormal, the embryo is labeled as normal. If 20 to 40 percent of the cells are abnormal, it is considered a low-level mosaic. When 40 to 80 percent of the cells are abnormal, it is labeled a high-level mosaic.

To oversimplify: mosaic development depends on agents, such as transcription factors, being placed locally in the egg by the mother. Regulative development depends in part on long-range gradients of positional information, such as that provided by the Hedgehog protein, that can pattern many cells at once.
