All but forgotten today, the Geneva Bible was the most widely read and influential English Bible of the 16th and 17th centuries.A superb translation, it was the product of the best Protestant scholars of the day and became the Bible of choice for many of the greatest writers and thinkers of that time. Men such as William Shakespeare, John Bunyan, and John Milton used the Geneva Bible in their writings. The Geneva Bible is unique among all other Bibles. It was the first Bible to use chapters and numbered verses and became the most popular version of its time because of its extensive marginal notes. These notes, written by Reformation leaders including John Calvin and others, were intended to help explain and interpret the Scriptures for the average reader. The Geneva Bible is regarded as history's first study Bible.
