This conclusion presents some closing thoughts on concepts covered in the preceding chapters of this book. The book explains that roofs are made of many materials and today's wooden, slate, or composite shingles were yesterday's thatch or matting, wooden poles or branches, skin or packed mud. It also describes that ancient built environment is multivarious in its manifestations and meanings, and these are likely forever beyond the total ken of archaeologists. The book focuses on careful excavations undertaken by these many archaeologists, their attention to detail, and their bravery in sometimes offering significant interpretive leaps in order to understand the essence, both physical and symbolic, of the home or structure presented to them in the archaeological record. The ongoing work of these and new generations of archaeologists will continue to build shingles on the rooftop.
