The stone coffers of the ancient GreeksAn example is the main hieron at Samothrace, where stone ceiling beams of the pronaos carried a coffered ceiling of marble slabs across a span of about 6.15 m (J.J. Coulton, Ancient Greek Architects at Work: Problems of Structure and Design; Cornell University Press) 1982:147; ) and RomansRoman wooden coffered ceilings are discussed in Roger Bradley Ulrich, Roman Woodworking, ch. "Roofing and ceilings" (Yale University Press) 2007. are the earliest surviving examples, but a seventh-century BC Etruscan chamber tomb in the necropolis of San Giuliano, which is cut in soft tufa-like stone reproduces a ceiling with beams and cross-beams lying on them, with flat panels filling the lacunae.Illustrated in Ulrich, fig 8.27. For centuries, it was thought that wooden coffers were first made by crossing the wooden beams of a ceiling in the Loire Valley châteaux of the early Renaissance. In 2012, however, archaeologists working under the Packard Humanities Institute at the House of the Telephus in Herculaneum discovered that wooden coffered ceilings were constructed in Roman times. Experimentation with the possible shapes in coffering, which solve problems of mathematical tiling, or tessellation, were a feature of Islamic as well as Renaissance architecture. The more complicated problems of diminishing the scale of the individual coffers were presented by the requirements of curved surfaces of vaults and domes.
