PROSTYLE

'Prostyle' is an architectural term defining free standing columns that are widely spaced apart in a row. The term is often used as an adjective when referring to the portico of a classical building which projects from the main structure. First used in Etruscan and Greek temples, the Romans later on incorporated this motif in their temples.
Example: Temple of Athena Nike, Akropolis, Athens, Greece
This architectural style probably originated in the eastern Greek isles in the 8th century B.C., however there are also many examples in archaic temples in southern Italy.
