I read this book while researching and writing an exhibit on "Science in the Time of Shakespeare" for my university's commemoration of the 400th anniversary of Shakespeare's death. It's a fascinating account of scientific activity and thinking in Elizabethan England centered on the burgeoning City of London, and makes the case that not all science was practiced by the luminaries of the age. In fact, Harkness warns the reader in the introduction that if you’ve come to read about Francis Bacon and his ilk, you’re in for a disappointment. A pivotal time in England intellectual history, the Age of Shakespeare saw the revival of classical learning that had begun in Italy in the 14th century. Large numbers of classical texts were translated into English for the first time and made more widely accessible. As important as the increased access to traditional scholarship was, however, the greatest intellectual advances in Elizabethan England occurred in new fields of learning spurred on by an increased emphasis on the practical applications of knowledge and a passion for tinkering (aka, experimentation). At the epicenter of the new learning was the City of London. The high degree of specialization in the city and a growing rate of literacy gave rise to a kind of grass-roots science practiced by glassmakers, distillers, instrument makers, alchemists, apothecaries, surgeons, midwives, and herbalists, who made medicines, planted botanical gardens, conducted experiments, and exchanged news, information, and ideas. It is these communities, which were a hot-bed of science, that historian Harkness meticulously and vividly chronicles. There, I've turned my exhibit text into a book review for this one!
