In this episode of Build Like a Roman, we look at the Roman carpenter and the wider world of ancient woodworkers.
From the faber tignarius, or structural carpenter, to joiners, furniture makers, shipwrights, and military craftsmen, we explore how timber shaped Roman buildings even when the wood itself has long disappeared.
This episode covers tools, training, collegia, timber supply, joinery, centring, roofs, and the technical knowledge behind Roman carpentry.
