It discusses a mariners' sanctuary interpretation and notes that evidence for indigenous inhabitants is much less clear in this corpus. His 2019 chapter examines cave movement, artificial light and the relation between signs and natural forms. The surviving objects document activity; the exact experience or rite of each visitor is reconstructed rather than directly observed.",
