Texas has recognized four plays as official state symbols:

Fandangle:

Focus is the area along the Clear Fork of the Brazos River. The story is recalled by an old-timer of the region - a cattleman who sits on the porch of a ranch house to reveal the past as he remembers it. The production consists of a series of segments, each based on historical material introduced by the narrators and then interpreted by one or more songs and dancing. Source: Handbook of Texas.

Texas:

Held in Palo Duro Canyon in a natural amphitheater - performed under the stars - a 600-foot cliff serves as the backdrop as you are taken into the past to reveal the struggles and celebrations of the early settlers, cowboys and Indians. Source: Amarillo KOA.

The Lone Star:

Presented in Galveston Island State Park Amphitheatre - part of the "Lone Star Legacy" festival . Galveston Island State Park has an interesting 500 year history.

Beyond the Sundown:

An outdoor Drama held by the Alabama-Coushatta Indian Reservation. Last produced in 1983.

The origin of theater goes back to prehistoric people acting out their hunting experiences and ancients singing and dancing for religious ceremonies. Theater as pure entertainment evolved slowly - the first recorded European theater was in ancient Greece about 600 BC (for a festival honoring the god of wine and fertility). A poet named Thespis won a dramatic play competition at this celebration and is so considered "the first actor" (origin of the term thespian)
