While the architect of Santa Maria Novella admitted to the frescoes of Ghirlandajo scarcely more of purple lancet light than had been shed by the morning sun through the veined alabasters of San Miniato; and looked to the rich blue of the quinquipartite vault above, as to the mosaic of the older concha, for conspicuous aid in the color decoration of the whole; the northern builder burst through the walls of his apse, poured over the eastern altar one unbroken blaze, and lifting his shafts like pines, and his walls like precipices, ministered to their miraculous stability by an infinite phalanx of sloped buttress and glittering pinnacle. The spire was the natural consummation. Internally, the sublimity of space in the cupola had been superseded by another kind of infinity in the prolongation of the nave; externally, the spherical surface had been proved, by the futility of Arabian efforts, incapable of decoration; its majesty depended on its simplicity, and its simplicity and leading forms were alike discordant with the rich rigidity of the body of the building. The campanile became, therefore, principal and central; its pyramidal termination was surrounded at the base by a group of pinnacles, and the spire itself, banded, or pierced into aerial tracery, crowned with its last enthusiastic effort the flamelike ascent of the perfect pile.
