The Mosaics with Geometric Patterns from the West and the East of the Roman Empire: The Hourglass Pattern and the Significance of the 'Le Décor Géométrique de la Mosaïque Romaine I-II '

The structures of a domus with two mosaics were discovered, and due to its features, it was decided to keep it integrated in the crypt of the Museum building in Bracara Augusta (Portugal). One of the mosaic floors consists on a chessboard pattern, with contrasting colours and the other is furnished with hourglass gridlines. A study of the hourglass motif integrated into different compositions will be presented here, helping to the international standardization of the description of the Roman Mosaic and trying to confront the same pattern from the West (Portugal) to the East (Turkey) of the Roman World.
