Sir Charles Eastlake in his "History of the Gothic Revival" testifies to this formal spirit from the point of view of another art than literature. "The age in which Batty Langley lived was an age in which it was customary to refer all matters of taste to rule and method. There was one standard of excellence in poetry--a standard that had its origin in the smooth distichs of heroic verse which Pope was the first to perfect, and which hundreds of later rhymers who lacked his nobler powers soon learned to imitate. In pictorial art, it was the grand school which exercised despotic sway over the efforts of genius and limited the painter's inventions to the field of Pagan mythology. In architecture, Vitruvius was the great authority. The graceful majesty of the Parthenon--the noble proportions of the temple of Theseus--the chaste enrichment which adorns the Choragic monument of Lysicrates, were ascribed less to the fertile imagination and refined perceptions of the ancient Greek, than to the dry and formal precepts which were invented centuries after their erection. Little was said of the magnificent sculpture which filled the metopes of the temple of the Minerva; but the exact height and breadth of the triglyphs between them were considered of the greatest importance. The exquisite drapery of caryatids and canephorae, no English artist, a hundred years ago, thought fit to imitate; but the cornices which they supposed were measured inch by inch with the utmost nicety. Ingenious devices were invented for enabling the artificer to reproduce, by a series of complicated curves, the profile of a Doric capital, which probably owed its form to the steady hand and uncontrolled taste of the designer. To put faith in many of the theories propounded by architectural authorities in the last century, would be to believe that some of the grandest monuments which the world has ever seen raised, owe their chief beauty to an accurate knowledge of arithmetic. The diameter of the column was divided into modules: the modules were divided into minutes; the minutes into fractions of themselves. A certain height was allotted to the shaft, another to the entablature. . . Sometimes the learned discussed how far apart the columns of a portico might be."[29]
