Cochlis
κοχλίς
Cochlis (κοχλίς) is an adjective used with columna by P. Victor (Reg. Urb. Rom. viii. and ix.) to denote such columns as the Trajan and Antonine [COLUMNA], probably on account of the spiral staircase (κοχλίας: COCLEA No. 4) with-in the column, rather than the spiral bas-relief on the outside, as he carefully gives the number of steps in each staircase.
