The town of SYBARITIS as in Sybaritic or Sybarite is where exactly and why was it so luxurious?

Answer 1

"Sybaris, a city of Magna Graecia, on the Gulf of Taranto, between the rivers Crathis (Crati) and Sybaris (Coscile), which now meet 3 miles from the sea, but in ancient times had independent mouths, was the oldest Greek colony in this region."

Also:

" The statements transmitted to us of the power and opulence of the city, as well as of the luxurious habits of its inhabitants, have indeed a very fabulous aspect, and are without doubt grossly exaggerated, but there is no reason to reject the main fact that Sybaris had in the sixth century BCE attained a degree of wealth and power unprecedented among Greek cities, and which excited the admiration of the rest of the Hellenic world. "
