Chimera of Arezzo sculpture was likely created as a votive offering to the Etruscan god Tinia. According to Greek mythology the Chimera or "she-goat" was a monstrous, fire-breathing hybrid creature of Lycia in Asia Minor, created by the binding of multiple animal parts to create a singular unnatural creature. As the offspring of Typhon and Echidna, the Chimera ravaged the lands of Lycia at a disastrous pace. Distressed by the destruction of his lands, the king of Lycia, Iobates, ordered a young warrior named Bellerophon to slay the dreaded Chimera, also as a favor to a neighboring king, Proetus. Proteus wanted Bellerophon dead
Chimera (genetics) give rise to the embryo proper. Embryos that are to be used in chimeras can further be genetically altered in order to specifically contribute to only one part of chimera. An example is the chimera built off of ES cells and tetraploid embryos, which are artificially made by electrofusion of two two-cell diploid embryos. The tetraploid embryo will exclusively give rise to the trophectoderm and primitive endoderm in the chimera. There are a variety of combinations that can give rise to a successful chimera mouse and — according to the goal of the experiment — an appropriate cell and embryo
