Mikołaj Łęczycki

Mikołaj Łęczycki (coat of arms: Niesobia), in Latin Nicolaus Lancicius (December 10, 1574 – March 30, 1653) was a Polish Jesuit, Catholic theologian, writer and mystic.

He spent several years in Rome, where he was studying and working with Niccolò Orlandini in the congregation's central archive to compile the history of Jesuits.

He was a professor at the Vilnius University and Lviv college, the rector in Kalisz and Kraków, then he was working in Nesvizh, Braniewo, and what is now the Czech Republic.

He was commonly considered a master of the spiritual life and a worker of miracles such as revelation, prophecy, healing, levitation, psychokinesis and bilocation.

He was the author of many theological writings, published together by Jean Bolland in two volumes as Opuscula spiritualia (Antwerp 1650) and separately many times all over Europe.
