The Long Silence is a short series about architectural surveys in the Maya Puuc region. Two volumes are available: The Long Silence and The Long Silence (2). In The Long Silence Stephan Merk describes the outcome of his Chunhuaymil project, an architectural survey of standing Maya Puuc ruins in a mostly untouched 100 square kilometer sector in Northeastern Campeche, M?xico. Nineteen ancient settlements were recorded, many of them for the first time. Their remaining architecture is presented here together with important hieroglyphic inscriptions from the sites. With additional contributions by Antonio Benavides Castillo, Daniel Gra?a-Behrens, Nikolai Grube, Carlos Pallan Gayol, and Julie Patrois.
