Obelisks served as resonating tone generators. Obelisks were created from single solid pieces for resonance purposes They functioned like a toning fork when struck The peaks were originally encased with electrum or gold
Egyptian obelisks were built from single solid pieces of stone. Some researchers have proposed they functioned as acoustic resonators — the pyramidion (peak) was typically gilded with electrum or gold. Historical sources document that later populations, including those during the Islamic period, deliberately toppled obelisks to recover the precious metal caps. The inscriptions primarily commemorated royal achievements and victories.
