Protosanctuary

Thus, Charlemagne's protopilgrimage brings him to a protosanctuary where the hero's body is already almost a statue,

An Egyptologist's mind immediately turns to the ancient Egyptian counterpart to such an imagined protosactuary: a reed hut that all late Egyptian temples, in their archaizing longing to return to the origins, sought to emulate in stone through the typically Egyptian temple features of inward-sloping walls, torus and corvetto cornice.

T. Desmond Alexander, The City of God and the Goal of Creation (Wheaton, IL: Crossway, 2018), makes the distinction (contra Beale) that Eden is not necessarily a “protosanctuary,” but rather, that each later sanctuary is “a restored garden of Eden” (19).
