was suggested, but to back up an assumption of age and to make certain points about pyramids and Greek civilization. She notes that not only are the results not very precise, but that other structures mentioned in the research are not in fact pyramids, e.g. a tomb alleged to be the tomb of Amphion and Zethus near Thebes, a structure at Stylidha (Thessaly) which is just a long wall, etc. She also notes the possibility that the stones that were dated might have been recycled from earlier constructions. She also notes that earlier research from the 1930s, confirmed in the 1980s by Fracchia, was ignored. She argues that they undertook their research using a novel, previously untested methodology in order to confirm a predetermined theory about the age of these structures. Liritzis responded in a journal article published in 2011, stating that Lefkowitz failed to understand and misinterpreted the methodology. A. Sampson wrote that it was "already proved that the monument stood on Early Helladic constructions, therefore it was built in a later time. Besides, the masonry of the pyramid, similar to that of Ligourio, leads us to the Classic or Late Classic years. A new method for dating the stone, recently applied to the pyramids, indicated a too early dating in the 4th and 3rd millennium BC, which of course cannot be accepted." Archaeologists on an ancient pyramid-like structure on the Greek island of Keros found the 4,000-year-old site with complex series of drainage tunnels and metalwork that was unusually sophisticated for the time. The discovery was made in September 2018. Dimensions The dimensions of the rectangular building surrounding the pyramid of Hellinikon are 7.03 meters by 9.07 metres. The external walls rise at a 60 degree angle up to 3.5 metres. The walls then become vertical in order to support the floor of the building. The entire monument is built from grey limestone from the district in the form of large blocks used in a trapezoidal/partially polygonal system.
