Definition: Is it art?
Mosaic is an art form which uses small pieces of materials placed together to create a unified whole.
The materials commonly used are marble or other stone, glass, pottery, mirror or foil-backed glass, or shells.
The word mosaic is from the Italian mosaico deriving from the Latin mosaicus and ultimately from the Greek
mouseios meaning belonging to the Muses, hence artistic. Each piece of material is a Tessera (plural: tesserae).
The space in between where the grout goes is an interstice.
Andamento is the word used to describe the movement and flow of Tesserae.
The 'opus', the Latin for 'work', is the way in which the pieces are cut and placed.
