The Freemason's Hall, Dublin. The Egyptian Revival style Royal Arch Chapter Room. It probably derives from the craze for Egyptology in the 1860s when the Freemason’s Hall was built. Life-sized sphinxes flank the ceremonial chair beneath an exotically coloured Egyptian baldacchino canopy. In Masonic lore, twin pillars symbolize the entrance to the Temple of Solomon, the repository for strength and wisdom.
