261 211 A kind of Ellipse or horseshoe is incidentally produced in DUCAL PALACE NICHES ST MARKS NICHES the foliation from Cremona p 46 1. it has on its north and south sides, the arch fig 2 p 48 1 more accurately fig 1 p 49 1 a very pure and graceful pointed arch and foliation, while on its eastern and western sides it has the only genuine egg shaped arch I ever saw, with an elliptical foliation carefully drawn with spandril at p 48 fig 3. The cusp in both arches is perfectly plain: the capitals are as in the south eastern niche. St Marks. Niches of St Marks. One is superior to all the rest that noted as (2) at p 60 St M. it is the last of all - farthest back from the square on North side, and on the projecting angle one of its sides has had the cusps restored. It is the simplest possible plan of a niche: it has four sides eight massy simple slabs of stone; cut into the cusps and mouldings; and a flat top with a hole in the centre - no vaulting whatever - then the pyramidal canopy is set on this level slab: This plan of niche is adopted in more elaborate works and an imitative vaulting filled in with plaster; but I like the simple and massy masonry of these square ones better. I am not certain of the jointing, but there is one joint certainly through the apex of each arch, and the other fitted at each angle among the dentils
