The term 'Pantheon Figures' refers to the GODS and BUSTS that were featured in the Pantheon, an ancient temple located in Rome. The four-letter solution for 'GODS' is DEUS, which is Latin for 'GOD'. The five-letter solution for 'BUSTS' is SCULP, which is derived from the Latin word 'sculptura', meaning 'to carve'. These figures were important to the ancient Romans, as they represented their GODS and goddesses, and were often used as symbols of power and authority.
