SCAMILLI IMPARES (" unequal steps," Fr. escabeaux inegales; Ger. Schutzstege) , in See also:

architecture, a See also:term quoted by See also:Vitruvius when referring to the rise given to the See also:stylobate in the centre of the front and sides of a See also:Greek See also:temple. His explanation is not clear; he states (iii. 4) that, if set out level, the stylobate would have the See also:appearance of being sunk in the centre, so that it is necessary that there should be an addition by means of small steps (scamilli impares). Ip See also:book v. See also:chap. 9, he again refers to the addition on the stylobate. The See also:interpretation of his meaning by Penrose and other authorities is generally assumed to be the addition which it was necessary to leave on the See also:lower frusta of the Doric See also:column, or on the lower portion of the See also:base of the Ionic column, so as to give them a proper bearing on the curved See also:surface of the stylobate; when levelling ground, however, it is sometimes the See also:custom to See also:fix at intervals small bricks or tiles which are piled up until the upper surfaces of all of them are absolutely level. If, as an alternative, these piles were so arranged as to rise towards the centre, instead of a level a slightly curved surface might be obtained, and the term "unequal steps" would apply to them. This was the See also:opinion of M. Bernouf, a See also:French author, who points out that scamillus is a diminutive of scamnum, a small step (Fr. See also:petit bane), which in some parts of See also:France is employed when levellirg the surface of areas or courts. According to Penrose the rise of the curved stylobate of the See also:Parthenon had already been obtained in the See also:stereobate carrying it, See also:long before the problem of bedding the columns on the See also:curve had arisen.
