Metamorphosis in folklore

Transubstantiation (Latin: transubstantiatio; Greek: μετουσίωσις metousiosis) is, according to the teaching of the Catholic Church, "the change of the whole substance of bread into the substance of the Body of Christ and of the whole substance of wine into the substance of the Blood of Christ". This change is brought about in the eucharistic prayer through the efficacy of the word of Christ and by the action of the Holy Spirit. However, "the outward characteristics of bread and wine, that is the 'eucharistic species', remain unaltered". In this teaching, the notions of "substance" and "transubstantiation" are not linked with any particular theory of metaphysics.

Apotheosis (from Ancient Greek ἀποθέωσις (apothéōsis), from ἀποθεόω/ἀποθεῶ (apotheóō/apotheô) 'to deify'), also called divinization or deification (from Latin deificatio 'making divine'), is the glorification of a subject to divine levels and, commonly, the treatment of a human being, any other living thing, or an abstract idea in the likeness of a deity.

Egeria (Ancient Greek: Ἠγερία) was a nymph attributed a legendary role in the early history of Rome as a divine consort and counselor of Numa Pompilius, the second king of Rome, to whom she imparted laws and rituals pertaining to ancient Roman religion. Her name is used as an eponym for a female advisor or counselor.
