Since the Middle Ages Lisbon has been a favourite site for the development and application of the theories of alchemist kings, masonic ministers, occult poets, followers of hermeticism and the secret knowledge of the Knights Templar, who found refuge in Portugal after they were banned from the rest of Europe in the 14th century. Vitor Manuel Adriao, acclaimed historian and philosopher, is heir to all this esoteric knowledge in Portugal. Here for the first time he reveals his incredible knowledge in this truly initiatory guide, with a mind-boggling interpretation of the arcana of a city which some consider is on the way to becoming the spiritual capital of Europe. An exceptional guide.
