Opus figlinum

Pavements in opus figlinum are usually made up of rectangular ceramic pottery or brick fragments of the same size, placed in groups of three. The orientation of adjacent groups is alternately vertical and horizontal; thus, the juxtaposition creates the visual impression of a braid pattern.^[2] The fragments are fixed to the subfloor with mortar. The stone fragments used are very small: about 2.5 x 2.5 x  2 cm.^[3]
