Jacopo Aconcio

Jacopo Aconcio, born around 1520 in Trento, Italy, was a multifaceted figure who served as a jurist, theologian, philosopher, and engineer. His early career included studying law and working as a notary. He later entered the service of Count Francesco Landriano and subsequently Cardinal Madruzzo, gaining exposure to court life and political affairs. During his service to Landriano, Aconcio became drawn to the ideas of the Reformation. Fearing persecution under Pope Paul IV, he fled Italy in 1557, seeking refuge in Basel and Zürich. In Switzerland, he published early works articulating his religious views and a treatise on intellectual inquiry. He later moved to Strasbourg and, in 1559, was invited to England due to his engineering expertise. In England, he proposed inventions, worked on draining marshland, and served as a military engineer, notably reviewing fortifications at Berwick Castle. Aconcio's most significant philosophical contribution is his work 'Stratagematum Satanae libri octo' (The Stratagems of Satan), published in 1565. In this book, he argued for religious tolerance by proposing that the core essentials of Christianity were few and that divergences on non-essential matters should not lead to division or persecution. He sought to identify the common ground of different Christian creeds, a radical idea for his time. Although his views were controversial and led to his exclusion from communion in the Dutch Reformed Church in London, his work had a lasting impact on liberal religious thought in England. Aconcio died around 1566 in London.
