ignorant of Ptolemy. And Letronne (Journal des Savans, 1821, p. 712) argues, that it is unlikely that Cleomedes should have known anything of refraction before Ptolemy, who says nothing of it in the Almagest (in which it must have appeared if he had been acquainted with it), but introduces the subject for the first time in his Optics. The same writer also endeavours to shew, from the longitude assigned by Cleomedes (p. 59) to the star Aldebaran, that he could not have written earlier than A. D. 186. Riccioli (Almag. Nov. vol. i. pp. xxxii. and 307) supposes, that the Cleomedes who wrote the Circular Theory lived a little after Poseidonius, and that another Cleomedes lived about A. D. 390. A treatise on Arithametic and another on the Sphere, attributed to a Cleomedes, are said to exist in MS. Vossius (de Nat. Art. p. 180b.) conject tures that Cleomedes wrote the work on Harmonics attributed to Cleonides or Euclid. [EUCLEIDES.]GRC 2008-06-9: I moved the section on the life of Cleomed
), and "Chalceutes" *Xalkeu/ths ("brasier"), and "Syntactes" *Sunta/kths ("Composer") conferred upon him by others (Epiph. Haeres. 63.1; and Tillemont. Mém. vol. iii. p. 497), appear to have been mere epithets, expressive of his assiduity. As he was in his seventeenth year, at the time of his father's death, which occurred apparently in April 203 (Huet. Origenian. 1.8), in the persecution which began in the tenth year of the reign of the Emperor Severus, his birth must be fixed in or about A. D. 186. The year 187, given in the Chronicon Paschale, is too late; and 185, given by most modern writers, too early. His father was Leonides (*Aewni/dhs), a devout Christian of Alexandria. Suidas (s. v. *)Wrige/nhs) calls him "bishop;" but his authority, unsupported by any ancient testimony, is insufficient to prove his episcopal character. Porphyry (apud Euseb. Hist. Eccl. 6.19) speaks of Origen, with whom he claimed to have been acquainted in early life, as having been educated a heathen, and
Perennis after the death of Paternus [PATERNUS] in A. D. 183, became sole praefect of the praetorians, and Commodus being completely sunk in debauchery and sloth, virtually ruled the empire. Having, however, rendered himself obnoxious to the soldiery, he was delivered up to them, and put to death, together with his wife and children, in A. D. 186 or 187. The narrative of Dio Cassius, who states that his death was demanded by a deputation of fifteen hundred dartmen, despatched for this special purpose from the turbulent army in Britain, and that these men, after having marched unmolested through France and Italy, on their approach to Rome, overawed the prince, although his own guards were far more numerous, is so improbable that we can scarcely give it credit. Moreover, Dion represents the character of Perennis in a very different light from that in which it is exhibited by other historians. Although he admits that Perennis procured the death of his colleague Paternus, in order that
