The mode of building with semicircular arches, massive piers, and thick walls with broad pilaster buttresses, was now laid aside; and the pointed arch, supported by more slender piers, with walls strengthened with graduating buttresses, of less width but of greater projection, were universally substituted in their stead. The windows, one of the most apparent marks of distinction, were at first long, narrow, and lancet-shaped: the heavy Norman ornaments, the zig-zag and other mouldings peculiar to the Norman and Semi-Norman styles, were now discarded; yet we often meet with certain decorative ornaments, as the tooth ornament, which, though sometimes found in late Norman work, is almost peculiar to the Early Pointed style; also the ball-flower, prevalent both in this and the style of the succeeding century. Many church towers were also capped with spires, which now first appear. This style prevailed generally throughout the thirteenth century, and is usually designated as the EARLY ENGLISH. [Illustration: Horsley Ch., Derbyshire.] Towards the close of the thirteenth century a perceptible, though gradual, transition took place to a richer and more ornamental mode of architecture. This was the style of the fourteenth century, and is known by the name of the DECORATED ENGLISH; but it chiefly flourished during the reigns of Edward the Second and Edward the Third, in the latter of which it attained a degree of perfection unequalled by preceding or subsequent ages. Some of the most prominent and distinctive marks of this style occur in the windows, which were greatly enlarged, and divided into many lights by mullions or tracery-bars running into various ramifications above, and dividing the heads into numerous compartments, forming either geometrical or flowing tracery. Triangular or pedimental canopies and pinnacles, more enriched than before with crockets and finials, yet without redundancy of ornament, also occur in the churches built during this century. [Illustration: Worstead Church, Norfolk.] In the latter part of the fourteenth century another transition, or gradual change of style, began to be effected, in the discrimination of which an obvious distinction again occurs in the composition of the windows, some of which are very large: for the mullion-bars, instead of branching off in the head, in a number of curved lines, are carried up vertically, so as to form _perpendicular_ divisions between the window-sill and the head, and do not present that combination of geometrical and flowing tracery observable in the style immediately preceding.
