To make a pavement made of mosaic, they followed a series of steps that were perfected over time. The manufacturing place was a special workshop. There, the first thing that was done was to design the painting and this work took the name of emblem (an esdrújula word), a word taken from Greek that means "something that is embedded in." After having designed the painting, a division was made according to the color. A papyrus or cloth template was then taken from each of these divided plots and the tiles were placed on this template following the previously chosen model. The tiles were placed inverted, that is, the good side that would be seen later had to be glued to the template. When this work was finished, the experts transported it on site so that the artist could finish his work there.

But before placing the tiles, the ground had to be well prepared to receive them. This was a very important task that required experience and skill. Firstly, it was leveled until it was horizontal but with a gentle and calculated inclination that would facilitate the sliding of the water towards the drains. The floor had to be firm and stable because a slight break in a single tile could lead to the degradation of the entire work. Scholars and archaeologists found a clear example of how this construction could be carried out in the famous Issus mosaic found in Pompeii. The firm to finally receive the tiles was constituted like this (from bottom to top):

The Roman mosaic is considered a painting made of stone. It is an art that lives off of painting as far as themes are concerned. The themes of a mosaic do not have their own identity, they are the same as those that can be found in painting, but it differs from it in that the perspective is false and forced. His inspiration is in the drawings of the tapestries of the fabrics and the pictorial work.

On the pavements of Roman domus from the century AD. C., the appearance of the image of Medusa "Medusa (mythology)") is typical, used as a prophylactic or protective sign for the inhabitants of the house.[3]​.

Roman mosaics are easy to discover for archaeologists and to date their number is very high, but they present great difficulty in conservation. The ideal place seems to be in museums where care, cleanliness, temperature, humidity, etc., are at their disposal, but the problem is the space that would be needed to store them in a worthy manner.
