Few have mastered the big picture better than artist David Macaulay. When a kid wants to know about pyramids or castles introduce him/her to Macaulay’s books. Macaulay dissects the parts in kid-obsessive detail while keeping his eye on the whole. And he shows how it all grows in time. His uncanny ability to x-ray complex places makes him the master guide to the built world. Of all his books, Underground is his most revelatory. Even adults will find themselves studying each page of “the city underneath the city” in aha enlightenment. Oh, so THAT’S how it works! Macaulay revisited three of his early books — Castle, Cathedral, and Mosque– creating new even more amazing visualizations, and combined the books into one new book called Built to Last. It’s a short course on civilization for kids.
