CATOBLEPAS.

It is found in Ethiopia near to the source Nigricapo. It is not a
very large animal, is sluggish in all its parts, and its head is so
large that it carries it with difficulty, in such wise that it
always droops towards the ground; otherwise it would be a great pest

[Footnote: Leonardo undoubtedly derived these remarks as to the
Catoblepas from Pliny, Hist. Nat. VIII. 21 (al. 32): _Apud Hesperios

modica alioquin, ceterisque membris iners, caput tantum praegrave
aegre ferens; alias internecio humani generis, omnibus qui oculos
ejus videre, confestim morientibus._ Aelian, _Hist. An._ gives a far
more minute description of the creature, but he says that it poisons
beasts not by its gaze, but by its venomous breath. Athenaeus 221 B,
mentions both. If Leonardo had known of these two passages, he would
scarcely have omitted the poisonous breath. (H. MULLER-STRUBING.)]

to the right. It is said that one
