Släbro is without question one of Sweden’s greatest and most remarkable rock carvings site. Situated near the River of Nyköping the carvings were discovered 1984 and can be dated back to the Bronze Age. They are unique because they are carved in a most unusual way. There are etchings on some ten different surfaces with a total of some 700 figures, mainly frame and circle figures. Many are unique in design, in particular the large stylised human figures in a position of adoration. The characteristics commonly found throughout carvings in the South of Sweden are missing. What is more, the Släbro carvings seem to bear no similarity to any other ancient carvings that have been discovered throughout Europe. The carvings date from 1800 – 400 BC and thus far the meaning behind them remains something of a mystery as it has proven to be extremely difficult to interpret the motif as it appears in literally hundreds of different ways.
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.
