Greek apokryphos: hidden, concealed, from apo (away) plus kryptein (to hide). Early usage praised esoteric books for the initiated; patristic usage turned it pejorative, spurious, doubtful. The Deuterocanonical books Catholics keep and Protestants dropped are the neutral sense; Enoch and friends are the full exile.
The video's frame: councils suppressed Enoch, catalogers deprioritized it, librarians restricted it. The real history is messier, Enoch fell from Western use through disuse more than decree, and its quotes survive embedded in Jude, which made it awkwardly semi-canonical forever.
Kryptein's family is the modern English shadow-lexicon of concealment: crypt, cryptic, cryptography, encrypt. Apocrypha and cryptography are siblings: one hides books, one hides messages, and the internet's entire security stack runs on the same root as the excluded books.
Who decided which books hid, and did they hide them or delete them?
