Prasiae or Prasiai (Ancient Greek: Πρασίαι) was a deme of ancient Attica on the east coast, between Potamus and Steiria, with an excellent harbour, from which the Theoria or sacred procession used to sail. Here was a temple of Apollo, and also the tomb of Erysichthon of Attica, who died at this place on his return from Delos.The ruins of the deme are seen on the north-east side of the bay. The harbour, now called Porto Rafti, is the best on the eastern coast of Attica, and is both deep and capacious. The entrance of the harbour is more than a mile in breadth; and in the centre of the entrance there is a rocky islet, upon which is a colossal statue of white marble, from which the harbour has derived its modem name, since it is commonly supposed to bear some resemblance to a tailor (ῥάφτης) at work. The statue evidently belongs to the Roman period, and probably to the first or second century after the Christian era. In the middle of the bay there is a rocky promontory with ruins of the middle ages upon it, which promontory Ludwig Ross supposes to be the Coroneia of Stephanus of Byzantium.

Myrrhinus or Myrrinous (Ancient Greek: Μυρρινοῦς) was a deme of ancient Attica. It lay to the east of Prasiae. Artemis Colaenis was worshipped at Myrrhinus; and in one of the inscriptions recovered at Merenda mention is made of a temple of Artemis Colaenis.The site of Myrrhinus is located near modern Merenda.The recent excavation at the new Equestrian Centre at Merenda, Markopoulo, where the ancient 𝘥𝘦𝘮𝘰𝘴 of Myrrhinous is located, gives some idea of the aspect of the centre of the aforesaid 𝘥𝘦𝘮𝘰𝘪. Here, in the middle of the flat space lying between the foothills of the homonymous mountain and the low vine-planted hills, a peripteral temple, probably dedicated to Artemis Kolainis, one of the most important in the city, and a sanctuary of Aphrodite have been brought to light at the crossroad of the two central arteries of the 𝘥𝘦𝘮𝘰𝘴, which are lined at intervals by cemeteries, classical tomb enclosures and two sanctuaries. Identified and excavated around the temple, at some distance, were three porticoed buildings of public character, in no particular order, the sanctuary of a phratry, and very close behind it, a monumental fountain that had been reconstructed in Roman times, while farmhouses extended on the small hills around.
