There are, as usual, people who think that mentioning of the names of Vamberg, Guessenbier, Doxat, Manet and Schroeder, the alleged military constructors of the Austrian Empire, in the favourable capacity of the constructors of the Fortress, is but a mere myth. (Others also mention the names of Keisersfeld and Marsigli, but now it is of no importance  for this story). This version of the “genesis” of the Fortress supports the story of the “Happening” of the rotten ground and the occurrence of immeasurably endless walls in the form of a labyrinth, within a single moment, later called “the Spark of Flame”. The version is advocated by some strange people to whom the Fortress represents their meeting-place, that is, some strange artists. One of the strange artists of the Happening involving the Spark of the Flame is Aleksandar D. Adžić - Adža. He realized in time that everything is so strange and unreal, that the “Spark of Fire” is so strong, and that experience outside the promised wall-girdled hill does not cause alchemic reaction which could give fresh inspiration to the Artists. Inspiration so strong, that neither an accidental passer-by, and later a guest, nor a love couple, nor a busy student, nor a locust tree, nor a fur tree, remain indifferent to the immeasurable energy of these strange people who consume it inexhaustibly. Aleksandar Adžić has finally got the feeling that the inexhaustible energy, that keeps dragging him deeper and deeper into the infinite labyrinth of the baked earth, tries to infuse the impression not only of the building, but also of a monumental outdoor sculpture: Petrovaradin Forra!
