Fresco "Thracian ritual of initiation through sanctification of bread, water and wine":

An important Orphic practice is associated with the ritual of consecration of bread, water and wine. The mural in the main lobby of the Hotel Park "Stara Zagora" is dedicated to that. Already it has been proven that significant structural changes and selected properties of these products take place after this Orphic ritual is performed. The same practice exists in Christianity. There are more convincing proofs and evidence on the relationship between religious teachings.
The Bible clearly describes the Last Supper of Jesus Christ with the Apostles.  Their rite of initiation is associated with bread, water and wine. Historical fact is that all Orphics i.e. societies "orpheidi" perceived a New Testament Christian teaching as an advanced theosophical model of Thracian Orphism.
