With as geographical subdivision: East / Egypt / Italy, Sicily and the west / the north and black sea.
Principally based on archeological finding of …. pottery… The study of the developments of the styles and the chronology of pottery an bronze articles is the fundament to interpret this period.
Why pottery?
Commonly used (replaces our glass, cans, plastic, carton …)
Breaks easily, and the shards are durable and worthless ( compare with metal articles that are resettled, wooden that decay)
As style evolves (fashion) 'easily' to date
Due to geographical features (material + style) fine to browse the streams on map

+
quite extensive
handy maps, sketches / pictures

-
quite boring except for a freak of pottery shards

conclusion:
quite boring description of the greek expansion from 8 -6 century BC based on pottery shards ( )
