SPIRAL
quasi in cochleam serpens: in cochleam retortus: muricatim intortus (Plin. 9 33 52). A spiral line spira: linea tortuosa (not spiralis): a spiral pillar columna cochlis (P. Vict. De Regg. urb. Rom. 8 9): a spiral stair-case *gradus quasi in cochleam serpentes or exstructi. ☞ Cochlea is without authority.

spiral (adj.):
1. spirae s. cochleae formam habens (spira denotes any kind of twist or coil: cochlea, the form of a snail-shell or screw): so, to wind in a s. direction, in cochleam serpere, Cels. 8, 10, 1.
2. less precisely: invŏlūtus, convŏlūtus, intortus, rĕtortus, tortĭlis: they form s. channels, involutos faciunt canales [et justam cochleae naturalemque imitationem], Vitr. 10, 6 (11), 2: (shells) with a s. top, vertice muricatim (= like the shell of the murex) intorto, Plin. 9, 33, 52: a s. or winding cave, specus in cochleam retortus, Col. 8, 17, init.: a s. horn, buccina tortilis, Ov. Met. 1, 336 (where is added an exact description of an expanding s. form, in latum quae turbine crescit ab imo). (N.B.--Spiralis is without authority: Forcell. gives the foll. definition of a s. line, linea flexuosa quae orbes facit non redeuntes in se: s. v. spira.)
