Most commonly, the phrase "Book of Enoch" refers to 1 Enoch, which is wholly extant only in the Ethiopic language. There are two other books named "Enoch": [[2 Enoch]] (surviving only in [[Church Slavonic|Old Slavonic]], c. first century AD; English translation by R. H. Charles (1896); and [[3 Enoch]] (surviving in Hebrew, c. fifth - sixth century). The numbering of these texts has been applied by scholars to distinguish the texts from one another. The remainder of this article deals with 1 Enoch only.
Whilst this book does not form part of the canon of [[Holy Scripture]] for the larger Christian Churches, various groups, including the [[Church of Ethiopia|Ethiopian Orthodox Church]], regard parts or all of 1 Enoch to be inspired Scripture. The currently known texts of this work are usually dated to [[Maccabean]] times (ca.
[[160s BC ]]).
The book contains descriptions of the movement of heavenly bodies (in connection with Enoch's trip to Heaven), and some parts of the book have been speculated about as containing instructions for the construction of a solar declinometer (the Uriel's machine theory).
