Final answer:
The statement about VI being composed from 1939 to 1940 as a series of 10 lyrical poems is false, as the passages provided do not support this claim.
Step-by-step explanation:
The statement given in the question is False. The passage provided from "VI" seems to reference classical forms of literature such as hexameter verse in poetry or Tragedy, but does not provide any information about a specific body of work composed in secrecy from 1939 to 1940 consisting of 10 lyrical poems with a preface, dedication, and prologue.
The additional provided references discuss various elements and historical contexts of modernist literature, the Dada movement in Berlin, and different poetry developments in different cultures and times. However, none of these relate to a secret composition from 1939 to 1940. Therefore, the literature or poetry series being described does not match any of the given references.
