The only styles at present in common use for domestic architecture, throughout the enlightened portions of Europe and America, are the Grecian and Gothic styles, or some modifications of these two distinct kinds of building. These modifications, which of themselves are now considered styles by most authors, are, the Roman and modern Italian styles, which have grown out of Greek architecture; the Castellated, the Tudor, the Elizabethan, and the rural Gothic or old English cottage styles, all of which are variations of Gothic architecture.
