    2. B. Of other objects: gubernaclum quolibet, Lucr. 4, 904; cf.: membra quocumque volt, Cic. Div. 1, 53, 120: tantum corpus, Lucr. 4, 900: globum eā celeritate, etc., Cic. N. D. 1, 10, 24; id. Arat. 61: equum magnā vi, Poët. ap. Quint. 8, 6, 9: amnis in alium cursum contortos et deflexos videmus, Cic. Div. 1, 19, 38: proram ad laevas undas, Verg.

  2. II. Trop. (mostly in Cic. and of rhet. matters; the metaphor taken from missiles which are brandished, that they may be discharged with greater force): (auditor) tamquam machinatione aliquā tum ad severitatem, tum ad remissionem animi est contorquendus, Cic. de Or. 2, 17, 72.
    So of discourse that is thrown out violently or forcibly, hurled: Demosthenis non tam vibrarent fulmina illa, nisi numeris contorta ferrentur, Cic. Or. 70, 234; cf. Quint. 10, 7, 14: quam rhetorice! quam copiose! quas sententias colligit! quae verba contorquet! ( = summā vi et impetu profert), hurls forth, Cic.

      * Comp.: concluduntur a Stoicis, Cic. Tusc. 3, 10, 22.
