In the novel 'Der Golem' by Gustav Meyrink I read that talmudists who know thieves' jargon are called 'bocherleh'. Is it true? And if it is so where do they use such specific language? Is it method to transmit secret knowledge?

You seem to be referring to the following passage in the 'Golem', in the chapter 'Nacht'/'Night':
*
Now, I don't know in which language you've read the book, and somehow, you being Ukrainian, I doubt you are able to manage the original German, but I (who have read the book many times in the original language and am obsessed with old Prague) can see no reference to 'talmudists who know thieves' jargon' being called 'bocherlech'.

The term 'bocherlech' Meyrink used here is a 'deutschmerisch' version of 'bochrim' (Heb. 'bachurim'), meaning nothing more than Yeshiva students. That Meyrink, himself a non-Jew, cannot be trusted entirely when it comes to Jewish customs, can also be deduced from the exotic term 'Landonim' (also amended to 'landomin' in the truly excruciatingly bad English translation) he uses, which means... nothing, actually. What he was probably referring to was 'Lamdonim', a term which could be translated with 'learned talmudists', if you like.
Also, in his re-telling of the well-known Prague folk tale of the 'chometzige Borchu', he mentions that this story happened on 'Schabbes Hagodel', something which any one reasonably aquainted with Jewish traditions and customs would recognise as rather odd, since that is the Schabbos before Pessach. The 'Chometzige Borchu' refers (in Western Yiddish) to the beginning of the Maariv at the end of Pessach (because that's when we're allowed to possess and consume chometz again).

All this doesn't mean that the 'Golem' is not a great work, in fact it's one of my favourite books, a classic of German phantastic literature, or that Meyrink's description of the Josefov before the 'Assanierung' is completely inaccurate: he just didn't know much about Judaism, since most if not all of his friends were Jewish, but very assimilated: the knowledge he could glean from them was bound to be half-baked and misunderstood. His description of the atmosphere of the old Judenstadt is peerless, as is his use of 'Prager Deutsch' (which, incidentally, can be useful to people wanting to know how that actually sounded like).

But there is definitely no place for theory of conspiracy of Jewish people holding secret knowledge in thieves jargon code against Ukrainian people, understandski?



*The only available, rather clumsy English translation of the passage:

I have read this book in Russian. The meaning of bocherlech as talmudists who know thieves jargon I looked in the footnote. Probably that was an explanation of the translator. ( Had he so rich fantasy? )

And of course, I didn't bear in mind theory of conspiracy against Ukrainian people. NO. NO. NO. I believe that Jewish people love Ukrainian people very much.

In the book "Der Golem" is present an image of 'the ghost without face'. In the Russian translation he is called Gavla d'Garmei and in the footnote is explained as 'spirit of bones' in Aramaic. Please say me how this image is mentioned in the original language?

It's mentioned three times: first by Hillel ('Haval Garim'), then once by Pernath and once by Laponder ('Haval Garmin').

Thank you very much. Such more precise definition amazed me...
