My research into Greek architecture is framed around two primary problems. The first is architectural: tracing the early development of Greek sacred architecture from crude thatched huts into elaborate, monumental temples built of stone and terracotta. The second is scientific and historical: illuminating the social and economic contexts of the craftsmen and architects who participated in this architectural revolution. The transition occurred over a few generations in the seventh century B.C., yet little is known about this formative period because of the challenges in restoring any of these temples accurately. In particular, I analyze the manufacturing techniques of early roof tiles, which were developed at this time and are the only remains of many early cult buildings. I have approached these problems with methods drawn from a wide variety of disciplines, including replication experiments; scientific tests of clays; ethnographic analogies between modern pottery works and ancient craft systems; and 3-D computer models of complete roofing systems for rendering accurate, informative, and legible reconstructions of lost early temples.
