Mysterium Press is an English publishing house and online shop, founded by Liam Barker in 2024.

The company launched with reprints of two of Hilaire Belloc’s historical biographies, Wolsey and Cranmer (both long out of print), which are part of a planned series of six books by Belloc on pivotal English figures.

We aim to produce truly beautiful editions of both out-of-print and newly commissioned works, encompassing theology, philosophy, history, art, poetry, and fiction.
