About the author

George Sinclair, who died in 1696, was a Scottish mathematician, engineer, and writer. He is generally described as the first Professor of Mathematics at the University of Glasgow, and he also worked on practical scientific subjects such as hydrostatics and mining.

As an author, he is best known today for Satan’s Invisible World Discovered, a collection of accounts about ghosts, witches, and other supernatural events. That unusual mix of scientific interests and strong belief in the unseen gives his work a distinctive place in 17th-century writing.

Some details of his early life remain uncertain, but sources connect him with the Lothians and with Glasgow, where he died. His books show a mind interested both in experiment and in marvels, which makes him an especially intriguing figure for modern readers.
