Observables and Ethnosemiotics. The Orthodox Liturgy of Vespers

The description of an Orthodox ceremony through the method of the participating observation is problematic, since the observation and the writing process are linear, while the structure of the ritual is nonlinear. In these cases, there is an unavoidable uncertainty in the description of meaning, forcing the writer to postulate structural stability to reconstruct the meaning by catalysis. From the uncertainty principle follows the notion of observable, mediating between the observed world and the point of view adopted by the observer.
