"The Life and Works of John Napier" is a comprehensive collection that for the first time unites all five works of John Napier in English. This compilation makes his significant mathematical and religious writings accessible to a wider audience. The four mathematical works, originally written in Latin, come from different time periods, including two from Napier's lifetime and one publication that appeared over 200 years after his death. The editors have written three introductory chapters that address Napier's life, his mathematical works, and his religious writings. These chapters provide new insights and a detailed biography that clarifies the often rumor-filled and speculative image of Napier. The authors have thoroughly examined the primary sources and offer fresh perspectives on Napier's life and works while revising many myths and assumptions about him.
