The megaron (; , , : megara ) was the great hall in very early Mycenean and ancient Greek palace complexes.
The megaron also contained the throne-room of the wanax, or Mycenaean ruler, whose throne was located in the main room with the central hearth. Similar architecture is found in the Ancient Near East, though the presence of the open portico, generally supported by columns, is particular to the Aegean. Megara are sometimes referred to as "long-rooms", as defined by their rectangular (non-square) shape and the position of their entrances, which are always along the shorter wall so that the depth of the space is larger than the width. There were often many rooms around the central megaron, such as archive rooms, offices, oil-press rooms, workshops, potteries, shrines, corridors, armories, and storerooms for such goods as wine, oil, and wheat. Evidence suggests that the megara of ancient Greece were often created using the construction techniques of wattle-and-daub and pisé.
The megaron is thought to have been used for sacrificial processions, as well as for royal functions and court meetings.
Historical use and purpose
Numerous sources indicate that the megaron was used in two central ways: first and foremost, it was used for religious ceremonies, while also being used to support residents as a dwelling space. Additionally, according to Valentin Müller, there is evidence for 32 different types of megaron throughout Greece and parts of Europe and Russia. Their use varied significantly depending on the time periods and locations in which they were built. Remnants of structures related to the traditional Greek megaron style buildings can be found in Thessaly dating back to the Neolithic Era. Müller asserts that these are some of the first known megaron, classifying them with the designation "Type 1" megarons. These initial structures were somewhat similar in design to those found in ancient Greece, but different in their material and roofing style and complexity. Müller has classified and archived a number of megaron "typings" which existed through the first, second and third periods of history, and shows how a number of ethnic groups participated in creating the original and archetypal model which later evolved into the classical Greek megaron structure. The Mycenaean megaron originated and evolved from the megaroid, or large hall-centered rectangular building, of mainland Greece dating back to the Late Neolithic and Early Bronze Age. With respect to its structural layout, the megaron includes a columned entrance, a pronaos and a central naos ("cella") with early versions of it having one of many roof types (i.e., pitched, flat, barrel). and since the aforesaid roof types are always destroyed in the remnants of the early megaron, the definite roof type is unknown. The walls, constructed out of mudbrick, were decorated with fresco paintings. and footbaths were also used in the megaron as attested in Homer's Odyssey where Odysseus's feet were washed by Eurycleia. The proportions involving a larger length than width are similar structurally to early Doric temples.
Construction techniques
Wattle-and-Daub and Pisé
The construction of the megaron style structure differs depending on the location and the specific example. Recent excavations of the small town of Karataş, Turkey, has led to the discovery of structural evidence that survived the ages, allowing archeologists and scholars to piece together theories as to how they were created. Some of the most prominent theories to come from this unearthing are the "Wattle-and-Daub" and "Pisé" construction techniques. In the ancient remains of the Karataş houses, archeologists analyzed the surviving foundations and walls of the megaron framework and observed that within each brick foundation were tightly packed tree saplings. The mudbrick surrounding these saplings provided for a dense and well taught structural foundation in which the megaron could be assembled. In other instances, the inner wood-work of the foundation was held in place with soil and rock, rather than mudbrick. Archeologist are unsure whether to call this a pure "Wattle-and-Daub" technique, or rather Pisé, as there is no indication that the inner saplings were woven together in order to help keep the wall's shape, or if the walls were rather held together by the surrounding mud, as done in typical Pisé fashion. A lot of these theories have gained popularity and are widely accepted in the effort to reconstruct the ancient megaron; however, some scholars such as Carl W. Blegen have argued that both the arguments presented by the lead supporters for the pitched and gabled roofs (Smith and Dinsmoor) provide insufficient evidence for determining what the actual roofing might have looked like and asserts that more pertinent studies need to be done before any conclusive judgements can be made. appear on Greek megaron frescoes, such as the one in the Pylos megaron, where a bull is depicted at the center of a Mycenaean procession. Different Greek cultures had their own unique megara; for example, the people of the Greek mainland tended to separate their central megaron from the other rooms whereas the Cretans did not do this.
Megaron of Mycenae
Notable information about the megaron of Mycenae has been reported by archeologist Hugh Plommer on his findings of a fully intact carved block from the megaron of Mycenae. His publication notes specific in situ measurements, photographs, physical details and descriptions of the stone left behind, along with a brief history of what had happened to the digging site, and even a supposition of the block's use – possibly the remnants of a fallen abacus from the porch of the megaron. The carved fragment of the megaron which he recovered was reportedly "broken into more than forty fragments", and was made from what he assumed to be a sort of reddish sandstone. This archeological fragment is particularly revealing of the history of the megaron of Mycenae, as much of the stone was also reportedly blackened around its edges, indicating that at some point there was a fire which raged through the building. After much archeological analysis, Plommer concluded that the abacus of the megaron was likely "80 cm" in both length and width, creating a solid square base linking the roof to the supporting pillar.
