A helm which is preserved in the Musée d’Artillerie in Paris probably exemplifies the transition between the Norman helmet and the barrel heaume. The conical Norman crown is preserved, but instead of the pendent neck and cheek guards and nasal, the head and face are entirely covered by a cylinder of iron, which is complete but for a vertical slit covered by a projecting nasal and two transverse occularia, one on either side. In England very early examples may be seen upon the monumental effigy of Hugh Fitz Eudo, in Kirkstead Chapel, Lincolnshire, and in a slightly modified form in the carvings of the Presbytery arcade of Worcester Cathedral, also in the groups of the Painted Chamber, Westminster. Holes for breathing purposes are entirely absent, the sole openings being a pair of horizontal occularia separated by a perpendicular band. In this class may be included the painted pot-heaume on a parchment MS. dating approximately from the year 1241, which is shown coloured in green and white diagonal stripes, and is now in the town library of Leipzic (Fig. 97). This flat-topped variety appears to have been viewed with much favour, for we have many examples of it in this period and in that immediately following. For instance, the seal of Roger de Bigod, Earl of Norfolk (1231 to 1240) (Fig. 98), exhibits a heaume which is flat-topped, furnished with two occularia, and nine small square breathing holes on either side, strengthened with cross pieces of iron. The seal of Richard de Clare, Earl of Gloucester and Hertford, who died in 1262 (Fig. 99), shows a flat topped helmet of cylindrical fashion, in which the occularium is formed by one ornamental wavy slit of which the lower edge is slightly cusped. The helmet of Hamelin, Earl of Surrey and Warenne, 1202 (Fig. 100), is of the round-topped variety, and is remarkable for the narrow occularium and the complete absence of any breathing holes. It is taken from the Cott. MS., Julius, C. VII.

The peculiarity of the surcoat covering the neck should be noticed, as it is uncommon at this period. From the examples given it will be apparent that from the year 1180 to 1250, the era under discussion, no heaume is represented with a movable visor, and this may be taken as a distinguishing feature, inasmuch as they appear shortly afterwards.
