A pyramidion (plural: pyramidia) is the capstone of an Egyptian pyramid or the upper section of an obelisk. Speakers of the Ancient Egyptian language referred to pyramidia as benbenet and associated the pyramid as a whole with the sacred benben stone.
Pyramidia were usually made of limestone, sandstone, basalt or granite, and were sometimes covered with plates of copper, gold or electrum. From the Middle Kingdom onward, they were often "inscribed with royal titles and religious symbols".
Merneferre Ay (also spelled Aya or Eje, sometimes known as Ay I) was an ancient Egyptian pharaoh of the mid 13th Dynasty. The longest reigning pharaoh of the 13th Dynasty, he ruled a likely fragmented Egypt for over 23 years in the early to mid 17th century BC. A pyramidion bearing his name shows that he possibly completed a pyramid, probably located in the necropolis of Memphis.
Merneferre Ay is the last pharaoh of the 13th Dynasty to be attested outside Upper Egypt. In spite of his long reign, the number of artefacts attributable to him is comparatively small. This may point to problems in Egypt at the time and indeed, by the end of his reign, "the administration [of the Egyptian state] seems to have completely collapsed". It is possible that the capital of Egypt since the early Middle Kingdom, Itjtawy was abandoned during or shortly after Ay's reign. For this reason, some scholars consider Merneferre Ay to be the last pharaoh of the Middle Kingdom of Egypt.
A pyramid (from Ancient Greek πυραμίς (puramís) 'pyramid', from the Egyptian pir-em-us, the vertical height of the structure.) is a structure whose visible surfaces are triangular in broad outline and converge toward the top, making the appearance roughly a pyramid in the geometric sense. The base of a pyramid can be of any polygon shape, such as triangular or quadrilateral, and its surface-lines either filled or stepped.
A pyramid has the majority of its mass closer to the ground with less mass towards the pyramidion at the apex. This is due to the gradual decrease in the cross-sectional area along the vertical axis with increasing elevation. This offers a weight distribution that allowed early civilizations to create monumental structures.
An obelisk (/ˈɒbəlɪsk/; from Ancient Greek ὀβελίσκος (obelískos), diminutive of ὀβελός (obelós) ' spit, nail, pointed pillar') is a tall, slender, tapered monument with four sides and a pyramidal or pyramidion top. Originally constructed by Ancient Egyptians and called tekhenu, the Greeks used the Greek term obeliskos to describe them, and this word passed into Latin and ultimately English. Though William Thomas used the term correctly in his Historie of Italie of 1549, by the late sixteenth century (after reduced contact with Italy following the excommunication of Queen Elizabeth), Shakespeare failed to distinguish between pyramids and obelisks in his plays and sonnets. Ancient obelisks are monolithic and consist of a single stone; most modern obelisks are made of several stones.
Electrum is a naturally occurring alloy of gold and silver, with trace amounts of copper and other metals. Its color ranges from pale to bright yellow, depending on the proportions of gold and silver. It has been produced artificially and is also known as "green gold".
Electrum was used as early as the third millennium BC in the Old Kingdom of Egypt, sometimes as an exterior coating to the pyramidia atop ancient Egyptian pyramids and obelisks. It was also used in the making of ancient drinking vessels. The first known metal coins made were of electrum, dating back to the end of the 7th century or the beginning of the 6th century BC.
The pyramidion of Amenemhat III is the capstone that once crowned the Black Pyramid at Dashur, Egypt. Crafted around 1850 BC, towards the end of the 12th Dynasty during the Middle Kingdom, it remained mostly intact and is now located in the Egyptian Museum in Cairo.
In the creation myth of the Heliopolitan form of ancient Egyptian religion,Benben was the mound that arose from the primordial waters (Nu), and upon which the creator deity Atum settled. The Benben stone is associated with the top stone of a pyramid, which is called a pyramid's pyramidion (or benbenet). It is also related to the obelisk.
