The Goths and Vandals overran Italy, Greece, Asia, and Africa, destroying most of their works of ancient architecture. Cultivating no art but that of war, these savage hordes could not be expected to take any interest in the beautiful forms and proportions of their habitations. From this time architecture assumed an entirely different aspect. The celebrated styles of Greece were unappreciated and forgotten; and modern architecture made its first appearance on the stage of existence. The Goths, in their conquering invasions, gradually extended it over Italy, France, Spain, Portugal, and Germany, into England. From the reign of Galienus may be reckoned the total extinction of the arts among the Romans. From this time until the sixth or seventh century, architecture was almost entirely neglected. The buildings which were erected during this suspension of the arts were very rude. Being constructed of the fragments of the edifices which had been demolished by the Visigoths in their unrestrained fury, and the builders being destitute of a proper knowledge of architecture, many sad blunders and extensive patch-work might have been seen in their construction - entablatures inverted, columns standing on their wrong ends, and other ridiculous arrangements characterized their clumsy work. The vast number of columns which the ruins around them afforded they used as piers in the construction of arcades - which by some is thought, after having passed through various changes, to have been the origin of the plan of the Gothic cathedral. Buildings generally, which are not of the classical styles, and which were erected after the fall of the Roman empire, have by some been indiscriminately included under the term Gothic. But the changes which architecture underwent during the Mediaeval age show that there were then several distinct modes of building.
