Note 99 — BOOK II. AN ACCOUNT OF THE WORLD AND THE ELEMENTS.

“Signifer.” The English term is taken from the Greek word Ζωδιακὸς, derived from Ζῶον; see Aristotle, De Mundo, cap. 2. p. 602. The word Zodiacus does not occur in Pliny, nor is it employed by Ptolemy; he names it λοξὸς κύκλος, obliquus circulus; Magn. Const. i. 7, 13, et alibi. It is used by Cicero, but professedly as a Greek term; Divin. ii. 89, and Arati Phænom. l. 317. It occurs in Hyginus, p. 57 et alibi, and in A. Gellius, 13. 9. Neither signifer taken substantively, nor zodiacus occur in Lucretius or in Manilius.
