οἴον ῥέοντος ἐν τῆ πορεία, τοῦτο γάρ εστι τό ῥεῖ ἀπιόντος, καὶ οῦχ ὥς τινες ἠπάτηνται, ῥᾳδίως ἔγνων ὑπολαμβάνοντες. Farnaby, upon the place in Virgil, observes, that _Deorum incessus est continuus et æqualis, non dimotis pedibus, neque transpositis_, ἀλλὰ κατὰ ῥύμην ἀέριον. Cornelius Schrevelius in the new Leyden notes saith, _Antiquissima quæque Deorum simulachra, quod observarunt viri magni, erant_ τοῦς πόδας συμβεβηκότα, _diique ipsi non gradiuntur sed fluunt_. Their statues were said to stand rather upon columns than upon legs, for they seem to have been nothing but columns shaped out into this or that figure, the base whereof carrying little of the representation of a foot. These things being premised, I suppose it easy for the intelligent reader to find out the true etymology of _Empusa, quasi_ ἐν ποσιν οῦσα, or βάινουσα, from going on her feet, whereas the other _gods_ and _demons_ had a different gait. If any can dislike this deduction, and think her so named from ἑνιπους, whereas she always went upon two legs, (if her shape permitted it) though she might draw the one after her, as a man doth a wooden leg: I say, if any, notwithstanding what hath been said, can join issue with the Doctor, my reply shall be Σοὶ μὲν ταῦτα δοκοῦντ’ ἐστὶν, ἐμὸι δὲ τάδε. Now, as to the words of Aristophanes upon which the Scholiast descants, they are these:--speaking of an apparition strangely shaped, sometimes like a camel, sometimes like an ox, a beautiful woman, a dog, &c. Bacchus replies: Ἔμπουσα τοινὺν γ’ἐστι. ΞΑ. πυρὶ γοῦν λάμπεται ἅπαν το προσωπον, καὶ σκελος χαλκοῦν ἔχει. ΔΙ. Νὴ τὸν Ποσειδῶ, καὶ βολιτινον θάτερον. ΞΑ. Σἁφ’ ἵσθι. The Scholiast hereupon tells us that _Empusa_, was Φαντασμα δαιμονιῶδες ὑπὸ Ἑκάτης ἐπιπεμπόμενον καὶ φαινόμενον τοἴς δυστυχοῦσιν, ὅ δοκεῖ πολλὰς μορφας αλλασσεω καὶ ὁι μεν φασιν ἀυτην μονοποδα εῖναι, καὶ ἐτυμολογοῦσιν’ ὁιονεὶ ἑνιποδα, διὰ το ἑνὶ ποδι κεχρῆσθαι. And this is all that is material in the Scholiast, except that he adds by and by, that βολιτινον σκελος is all one with the leg of an ass. And this very text and Scholiast is that to which all the authors he names, and more, do refer.
