The Longstone is a megalithic monument near the village of Mottistone, close to the south west coast of the Isle of Wight. It is the only megalithic monument on the Island.
The Longstone consists of two pieces of local greensand sandstone probably from a vein 100 metres away. The larger stands at 3.9 metres and the smaller lies at its foot. They are on the edge of a wood in small fenced enclosure just off Strawberry Lane, near Mottistone. The name Mottistone (the Speaker's or pleader's stone) almost certainly derives from the Longstone. The stones and the surrounding land are in the care of the National Trust and are open to the public.
Until the mid nineteenth century the smaller stone was further south but in 1856 a local landowner, Lord Dillon, had it turned over to discover if it had a mortise hole (it did not). Its present position has led to fanciful tales of its being a sacrificial altar stone and so, in common with many other megalithic monuments, modern pagan meetings and rituals are associated with it.
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.
