"Father Francis (Franz) Spirago (1862-1942) was a 19th century Bohemian theologian with a sense of humor who wrote several works to remedy inadequate catechesis among the faithful.
>Fr. Spirago wrote seven types of catechisms, the chief of which is The Catechism Explained, but he also wrote on a multitude of topics, ranging from works on the end times and prophecies, to rules of prudence and pastoral care."
