Ale's Stones (Ales stenar) is a megalithic monument which consists of a stone ship 67 meters long formed by 59 large boulders of sandstone, weighing up to 1.8 tonnes each. According to Scanian folklore, a legendary king called King Ale lies buried there.
The carbon-14 dating system for organic remains has provided seven results at the site. One indicates that the material is around 5,500 years old whereas the remaining six indicate a date about 1,400 years ago. The latter is considered to be the most likely time for Ales Stenar to have been created. That would place its creation towards the end of the Nordic Iron Age.
In 1989, during the first archaeological excavations performed in order to scientifically investigate and date the monument, archaeologists found a decorated clay pot with burned human bones inside the ship setting. The bones are thought to come from a pyre and to have been placed in the pot at a later date. The pot's contents varied in age; some material was from 330-540 CE while a piece of charred food crust also found inside was determined to be from 540-650 CE. The archaeologists working on the project also found birch charcoal remains from 540-650 CE underneath an undisturbed boulder. According to the Swedish National Heritage Board, carbon-14 dating of the organic material from the site indicates that six of the samples are from around 600 CE, while one sample is from ca. 3500 BCE. The diverging sample came from soot-covered stones that are believed to be the remnants of an older hearth, found close to the ship setting. On the basis of these results, the Swedish National Heritage Board has set a suggested date of creation for Ales Stenar to 1,400 BP, which is the year 600 CE.
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.
