Exterior of Hagia Sophia
"Exterior of the Church of Sta. Sophia at Constantinople. Although the impression conveyed by this church is not so pure and simple as that which the basilicas produce, still its outlines are magnificent and imposing. The exterior displayed a novel divergency from the normal standard. Whist hitherto the antique form of the roof had been preserved, it was now replaced by a totally different one: inasmuch as the vaulting, at least of the domes, was visible from the outside without any screen, or the only covering it had was one of polished metal."
