 The concept of hybridity was fraught with negative connotations from its incipience.The Greeks and Romans borrowed extensively from other civilizations, the Egyptians and Persians in particular, and creating "ipso facto" hybridized cultures, but regarded unfavourably biological hybridity.Aristotle, Plato and Pericles were all opposed to racial mixing between Greeks and "barbarians" and viewed biological hybridity as a source of racial degeneration and social disorder.
