An obelisk is a tall, slender monument that tapers as it rises, with four sides and a pyramidal top, often referred to as a pyramidion. Originally constructed by the ancient Egyptians, obelisks were usually monolithic, carved from a single piece of stone—commonly red granite from the Aswan quarries. They typically stand square or rectangular at the base and are adorned with hieroglyphs that often dedicate the monument to the sun god or commemorate rulers. Obelisks were commonly erected in pairs at the entrances of ancient Egyptian temples as symbols of the sun god Ra and as monuments to the fusion of divine and earthly power held by the pharaoh. The top was often covered with electrum, a gold and silver alloy. The form and symbolism of obelisks have lasted through time and can be found today around the world, not only in Egypt but also in various major cities where ancient Egyptian obelisks were transported. In summary, an obelisk is a monumental stone pillar characterized by its tapering shape and pyramidal top, originally built to honor gods, commemorate significant events or individuals, and symbolize solar power and royal authority in ancient Egypt. Modern obelisks may be constructed from multiple stones rather than a single monolith. This architectural form represents an impressive blend of artistry, technical skill, and religious symbolism from ancient times to today.
