[87] There is a very curious example of Italian tracery in the church of San Giacomo, in Bologna. This is a two-light window, composed of a series of slabs of stones, pierced with geometrical figures and supported by shafts. It has, beginning at the sill and reckoning upwards—1, two lights divided by a shaft monial; 2, a slab pierced with two trefoiled heads to the lights; 3, a large transome panel of stone pierced with a quatrefoil and two trefoils; 4, same as 1st; 5, same as 2nd; 6, the arch, whose tympanum is filled in with another pierced slab of stone. It will be seen that the construction of such a window as this is altogether unlike that of any English window.

[89] The windows in the Castle of S. Angelo, between Lodi and Pavia, are the only examples I met with of the use of brick for monials. In Northern Germany, on the contrary, where the shaft was almost unknown, brick monials are universal, and generally unsatisfactory in their effect.
