Excerpt from Gizmodo
Written by Eve Peyser
The first edition of Sir Isaac Newton’s Principia Mathematica was sold for $3.7 million at Christie’s on Wednesday, becoming the most expensive printed science book ever sold at auction—[insert joke about outrageous college textbook prices]. Albert Einstein described Newton’s seminal 1687 work as “perhaps the greatest intellectual stride that it has ever been granted to any man to make.”
Bound in goatskin, this is one the first 80 editions of Principia Mathematica printed for continental Europe. The unnamed bidder who purchased it gave three times the price Christie’s expected. In the past five decades, only one other original animal skin-bound copy of Principia Mathematica has been auctioned—a leather copy made for King James II sold at Christie’s for $2.5 million in December 2013.
