   • c. 80 BCE – 15 BCE, Vitruvius, De Architectura 7.4.2.7:

     deinde insuper erectae mammatae tegulae ab imo ad summum ad parietem figantur, quarum interiores partes curiosius picentur, ut ab se respuant liquorem; item in imo et in summo supra camaram habeant spiramenta.

     Over them tegulae mammatae are fixed upright, from the bottom to the top of the wall; and the inner surfaces of these are to be carefully pitched over, that they may resist the moisture; they are, moreover, to have air-holes at bottom, and at top above the vault. —Tony Rook, Roman Building Techniques

"Tegula mammata" was a Roman architectural term referring to a type of tile that had conical projections or bosses on the wall-facing side, thus creating a hollow space underneath when installed.^[1] This void was used in wall heating systems to circulate hot air.
