Simply, a beautiful and breathtaking book. Full of marvels and curiousities, each chapter opens out to show the wider maps and ideas we thought we knew about...small details from the paintings are peered closely at, and behind them the seventeenth-century world of travel and trade, narrated through human encounters and stories. He writes wonderfully well and with such clarity about often complex issues, effortlessly moving the focus and scene from place to place: so there's a lovely rhythm about the book as he paces the (frequent) surprises subtly and narrates them with a drole and deceptively easy style. I started to read the other day and was still sat there seven hours later, transfixed by it, slowing up the pace of reading, not wanting it to end.
