Lewis & Short

cerus, in carmine Saliari intellegitur creator, Fest. s. v. matrem matutam, p. 122 Müll.
Here perhaps belongs also another passage from the Carm. Saliorum: duomis ceruses, Varr. L. L. 7, § 26 Müll.; another writing KERVS in KERI POCOLOM, an inscription on a clay vase; the word is a masc. form to the fem. Ceres, and denotes the creator; from cer = Sanscr. kri, to make; v. Ceres.
