Daniele Venturi (Florence, 1965) was a concert interpreter of Bach. He is the author of RUAT. Analisi di sincronicità storiche riferite al simbolismo esoterico (Polistampa, 2010). For over two decades, he has been investigating — using documentary and formal verification methods — a singular case within the field of synchronicity studies: the epistemological problem posed by the documented convergence of a historical-biographical order and a formal order, from which an octagonally symmetric geometric structure emerged.
