No text, but a visual code

I took a quick look around to make sure I remembered this correctly... In Hymni Heroici tres (1511), Mirandola refers to "Hieroglyphicis Aegyptus" in a section with a big title with the word Egypt, so even though the context is obviously Egypt, he still felt the need to specify that he was talking about Egyptian hieroglyphics (and not some other foreign alphabet).

Oonselius's Hieroglyphica sacra (1627) discusses a variety of sacred languages in numerous contexts (including Jerusalem), only one of which is Egyptian. In other words, he uses hieroglyphics as a general reference to foreign scripts.
