It also discusses claims of a solar or sundial function, while saying the origin of that belief is unclear and may be modern. Clark and Reepmeyer's later archaeological study places Heketa's monuments within the growth of chiefly ceremonies and sacred authority. Its fourteenth-century ceremonial framework differs from the submission's traditional construction account around 1200, and the different claims should not be silently reconciled.",
