The part from b to c of the cyma being in light, itsshadow will be the curve c b, wherein, if it be required on a large scale, any numberof pomts may be taken to determine its form by means of correspondent points on the planas for the parts already described. 2468. Fif/. 844. is the plan and elevation of some steps, siurounded by a wall, and P inthe plan is a square pillar standing in front of them. It will be seen that tlie line .\ 13. S28 THEORY OF ARCHITECTURE. Book II. corresponds with ab on the plan, as do the pointsE, F, G, H with efgh, from which verticals deter-mine them in the elevation. The projection of theplinth on the lower step is found by KJ and acorresponding line and vertical, which, to preventconfusion, is not shown on the plan. The shadowof tlie square pillar P is found in a similar niannerby the line CD corresponding to cd on the plan, theshadows on the steps being also determined by thejKiints L, M, N, O, through the medium of verticalsfrom 1, m, n, o. The left-hand side of the shadow ofthe pillar is determined in a similar way by theline pq, and QR in the elevation is given by qr inthe plan, and is the line representing the back psof the top of the pillar. It will be observed thatwe have not described any of the preceding dia-grams in a strict way, neithe
