Chapter XIII.—Mention of the Heretic Colarbasus; Alliance Between Heresy and the Pythagorean Philosophy. Certain, adhering partly to these, as if having propounded great conclusions, and supposed things worthy of reason, have framed enormous and endless heresies; and one of these is Colarbasus, 192 who attempts to explain religion by measures and numbers. And others there are (who act) in like manner, whose tenets we shall explain when we commence to speak of what concerns those who give heed to Pythagorean calculation as possible; and uttering vain prophecies, hastily assume 193 as secure the philosophy by numbers and elements. Now certain (speculators), appropriating 194 similar reasonings from these, deceive unsophisticated individuals, alleging themselves endued with foresight; 195 sometimes, after uttering many predictions, happening on a single fulfilment, and not abashed by many failures, but making their boast in this one. Neither shall I pass over the witless philosophy of these men; but, after explaining it, I shall prove that those who attempt to form a system of religion out of these (aforesaid elements), are disciples of a school 196 weak and full of knavery. 192     Colarbasus is afterwards mentioned in company with Marcus the heretic, at the beginning and end of book vi. of The Refutation . 193     This word ( σχεδιάζουσι ), more than once used by Hippolytus, is applied to anything done offhand, e.g., an extempore speech. It therefore might be made to designate immaturity of opinion. Σχεδία means something hastily put together, viz., a raft; σχέδιος , sudden. 194     Schneidewin suggests ὅμως instead of οἱμοίως . The word ( ἐρανισάμενοι ) translated “appropriating” is derived from ἔρανος , which signifies a meal to which those who partake of it have each contributed some dish (pic-nic). The term, therefore, is an expressive one for Hippolytus’ purpose. 195     προγνωστικοὺς .  Some would read πρὸς γνωστικοὺς . 196     Some propose δόξης , “opinion.” Hippolytus, however, used the word ῥίζης (translated “school”) in a similar way at the end of chap. i. of book iv.  “Novelty” is read instead of “knavery;” and for ἀναπλέου , “full,” is proposed (1) ἀναπλέοντας , (a) ἀναπτεροῦντας .
