mud brick

“CALDE OF THE LONG SUN by Gene Wolfe Chapter 1 -- The Slaves of Scylla As unruffled by the disturbances shaking the city as by the furious thunderstorm that threatened with every gust to throw down its shiprock and return its mud brick to the parent mud, His Cognizance Patera Quetzal, Prolocutor of the Chapter of This Our Holy City of Viron, studied his present sere and sallow features in the polished belly of the silver teapot.”

Calde of the Long Sun

“ Like Artoom, it had thick mud brick walls and a heavy gate.”
