King Doniert's Stone consists of two pieces of a decorated 9th-century cross near St Cleer. The inscription is believed to commemorate Dungarth, King of Cornwall, who died around 875.
The site consists of the remains of two granite cross-shaft fragments dating from the 9th–11th century, and an underground passage and cross-shaped chamber below the crosses, thought to be either the remains of tin workings or a possible oratory. The northern cross, the Doniert Stone, is 1.37 metres high with panels of interlace decoration on three sides and inscription doniert rogavit pro anima carved in half uncial or insular script. The inscription translates as 'Doniert has asked [for this to be made] for his soul['s sake]'.
The inscription is thought to refer to the local ruler Dumgarth (or Dwingarth), who is recorded in the early Welsh chronicle known as the Annales Cambriae as having drowned in around 875 AD. It has a mortise slot and a plinth at the base. It is notable for being the only inscription to a Cornish King also known from documentary sources.
The southern cross, sometimes referred to as the Other Half Stone, is 2.1 metres (6 ft 11 in) high with a panel of interlace decoration on the east face, a broken mortise slot at the top and a plinth at the bottom.
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.
