There are over 100 rock carvings depicting rich and wide variation of themes in Torsbo, including the longest boat carving in Sweden (4,5m). There are also figures of a tree, and several warriors carrying swords. Many of the warriors are depicted as having enlarged calves, a feature that is typical for this area. It cannot be rulled out that several of the carvings were made by the same person. The carvings as a whole have, however, been made over a period of some 1000 years. Many of the ships date from the early Bronze age, around 1800-1500 B.C. while most of the warriors are thought to date from the end of the Bronze Age, around 700-500 B.C. There are often features of both motifs on the same rock face, indicating that the place was used and was a holy place for many generations.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
