Note 20 — ADDENDA TO LECTURES I. AND II.

The constructive value of Gothic architecture is, however, far greater than that of Romanesque, as the pointed arch is not only susceptible of an infinite variety of forms and applications to the weight to be sustained, but it possesses, in the outline given to its masonry at its perfect periods, the means of self-sustainment to a far greater degree than the round arch. I pointed out, for, I believe, the first time, the meaning and constructive value of the Gothic cusp, in page 129 of the first volume of the "Stones of Venice." That statement was first denied, and then taken advantage of, by modern architects; and considering how often it has been alleged that I have no practical knowledge of architecture, it cannot but be matter of some triumph to me, to find "The Builder," of the 21st January, 1854, describing as a new invention, the successful application to a church in Carlow of the principle which I laid down in the year 1851.
