Is Achilles Greek?
Yes.His father,Peleus,was the king of Phthia(which is located in
Larisa of Thessaly,where today there is a city called "Farsala")and
his mother,"Thetis", came from an island of the Aegean sea(which is
why she was believed to be a sea nymph).His descendants today are
believed to be the Vlachs that live on the mountain Pindos,because
they are the only ones that own the characteristical "molossus",a
specific breed of shepherd dogs that only the descendants from
Achilles,the "Molossians" (who were a well known greek tribe) used
to own from the ancient times.No other greek tribe owned these
dogs,which is why the Molossians gave to this breed of dog their
name (molossus).
