Pseudepigrapha (also anglicized as "pseudepigraph" or "pseudepigraphs") are falsely attributed works, texts whose claimed author is not the true author, or a work whose real author attributed it to a figure of the past.
What is the difference between Pseudepigrapha and Apocrypha?
Apocrypha per se are outside the Hebrew Bible canon, not considered divinely inspired but regarded as worthy of study by the faithful. Pseudepigrapha are spurious works ostensibly written by a biblical figure. Deuterocanonical works are those that are accepted in one canon but not in all.
Why is the pseudepigrapha important?
The Pseudepigrapha are essential to understanding the historical developments and foundations of Judaism and Christianity as they relate to their historical context and demonstrate the various strands of traditions and types of communities.
