Greek mythology
Astraea was the virgin goddess of justice and equity. It was represented by a surrounded bright halo, with wings and carrying the rays of Zeus in one hand and a torch in the other.
It was the last immortal that lived with human during the Golden Age; she ascended into heaven with the arrival of the Bronze Age, in which human lost their purity.
(5) Astraea is related with fair trade, based on a correct valuation and in which there is a correct balance between what is given and what is received (11:7 resonance with Sylvia).
