The Apocrypha are religious texts that are in some versions of the Catholic Bible. Other versions omit them. The word comes from Ancient Greek ἀπόκρυφα (apokrypha). Apocrypha means those that were hidden. Generally, the term is applied to writings that were not part of the canon. There are several reasons why these texts were not included. The texts might only have been known to few people, or they might have been left out because their content does not fit well into that of the other books of the Bible. Some of the apocrypha were written at a later date, and were therefore not included.
