Pliny’s Natural History records the ichneumon among Egyptian and African animals in Roman encyclopedic speech — the snake-fighting mongoose of that handbook. A named mongoose in that encyclopedia, not a modern pest-control dump and not a jackal flatten.
Herodotus’s Egyptian logos names the ichneumon among sacred and Nile fauna. A named mongoose (the published entity for that animal) in that traveler’s speech, not cat as the household keep-apart already walked and not a modern petting-zoo dump.
