Of his numerous other Bohemian works we may mention the Postilla (collection of sermons), the treatises 0 poznani testy grave k spaseni (the true road to salvation) and O svatokupectvi (on simony), and a large collection of letters; those written in prison are very touching.
A Bohemian work by Archbishop John of Rokycan has also been preserved; it is entitled Postilla and is similar though inferior to the work of Huss that bears the same name.
Among his other works his Postilla and polemical writings in the form of letters to Archbishop John of Rokycan and Bishop Nicolas of Pelhfimov deserve mention.
Among the authentic works of Nicolaus of Lyra are: (1) two commentaries on the whole Bible, one (Postilla litteralis, 1322-1331) following the literal sense, the other (Postilla mystica seu moralis, 1339) following the mystic sense.
His works, especially the Postilla litteralis, were very popular in the 14th and 15th centuries, but produced few imitators.
