Religio Medici (The Religion of a Doctor) by Sir Thomas Browne is a spiritual testament and early psychological self-portrait. Published in the17th century, it became a European best-seller which brought its author fame at home and abroad. Structured upon the Christian virtues of Faith, Hope and Charity, Browne expresses his beliefs in the doctrine of sola fide, the existence of hell, the Last Judgment, the resurrection and other tenets of Christianity.

Sir Thomas Browne (1605 – 1682) was an English polymath and author of varied works which reveal his wide learning in diverse fields including science and medicine, religion and the esoteric. His writings display a deep curiosity towards the natural world, influenced by the scientific revolution of Baconian enquiry and are permeated by references to Classical and Biblical sources as well as the idiosyncrasies of his own personality.
