Amphitheater, Roman city of Augusta Emerita, Merida, Spain. Constructed in 8 BC to complement the theater built next to it some 7 years earlier. This fighting ground was used until the fall of the Empire in the 4th century and ended partially underground. It was uncovered in 1912…[1920×1080] [OC]

…A construction more in the popular taste than the theater, the amphitheater was intended for fights between gladiators, wild beasts, or between men and wild beasts. It consists of a central elliptical arena surrounded by grandstands capable of seating 15,000 spectators, divided, as in the theater, into three zones. Of these three zones, only the lower one remains today, as the two upper ones were used, after falling into disuse, as quarry for the adjacent buildings.

Colonia Iulia Augusta Emerita was an ancient Roman city founded in 25 BC by the legate Publius Carisius on the orders of Augustus to settle discharged soldiers (emeritus) of the X Gemina and V Alaudae legions who had fought in the Cantabrian Wars. From ca. 15 BC it was the capital of the new Hispanic province of Lusitania, and, from the end of the 3rd century, the capital of the Diocese of Hispania. It was attached to the Papiria tribe.

The Papiria tribe is one of the 35 Roman tribes, to which every Roman citizen was assigned in order to exercise their right to vote in the Comitia tributa or tribal elections. It was considered a rustic tribe, compared to the four urban tribes. It was created in 498 BC and its name refers to the Papiria gens, one of the traditional gens of Roman society.
