Artist Miler Lagos is building a library, but think twice before pulling out a book. For his recent installation called Home at the Magnan Metz Gallery in New York City, Lagos constructed an entirely self-supporting dome out of nothing but books.
The structure is prototypical of corbel dome construction, in which stones or bricks are layered atop one another, gradually cantilevering out until reaching its apex. This construction technique is one of the oldest in the world; the Mycenaean Treasury of Atreus, built around 1250 BCE (see below), was the tallest and widest dome in the world for over a thousand years (finally beat out by the Pantheon).
