In its dramaturgical structure, the libretto concentrates on the three
characters of the "Somnium", but does consider some aspects of Kepler's
biography.
The central characters of the dream are DURACOTUS (baritone) representing the
imaginary "second self" of Kepler; FIOLXHILDE (mezzo-soprano) is an image of
Katharina, Kepler's mother who had been imputed of sorcery; and finally the
DEMON (actor) who reports from and tells about the geography of Levania (also
"Lebana" which is Hebraic for "Moon").
The score is divided into six scenes: Forgetting; The Translation into The
Dream; The Voyage; The Vision; The Spell for Awakening; The Recollection
following each other without interruption.
"... the contemporary human believes in what he reads in the papers, but not in what is in the stars." (Ernst Jünger)
For five years, the young Duracotus has studied the science of the skies
with his master Tycho Brahe in Denmark. Now he is returning home from abroad.
FIOLXHILDE, his mother, calls him and proposes him to visit Levania; Duracotus
begs her to unveil the "secret knowledge" that even the masters of astronomy -
of which he is a connaisseur himself - have not yet achieved.
Through the power of his magic spells, the Demon of Levania appears, telling of
the difficulties of a voyage through the cosmos, but also describing the
celestial phenomena as they can be observed from Levania.
The work ends with Duracotus' awakening from his dream that has been a tale of magic as well as of science, a tale that the magic fairies of times long bygone will hand over in a night unknown.
"One of the strange aspects of dreaming is the possible connection of any facts whatsoever." (Paul Valèry)
