The great helm or heaume, without a movable visor, is of English origin. It first appeared about the middle of the twelfth century, and was worn over a hood of mail, which was then found inadequate to resist either the lance or a heavy blow from a battle-axe or mace, or even a stroke from the then greatly improved sword. The helm had the effect of distributing the force of the blow, and to a certain extent parried it. The second seal of Richard I. shows him in a great helm, which is either flat-topped or conical, with the nasal, and is obviously derived from the antique. The cylindrical or flat-topped variety came into vogue towards the end of the twelfth century. There is an example of the conical form in the Museum of Artillery at Paris, and one of the nearly flat-topped variety, rising very slightly towards the centre, in the Tower of London. The great helm is often represented as a pillow for the head in effigies. The next form, which is in great variety, the knight’s early tilting helm, was used pre-eminently for jousting; the visored bassinet being worn generally in battle. It was introduced to resist the heavy lance charge. This form was hemispherical, conical, or cylindrical, with an aventail to cover the face,[13] and ocularia or slits for vision, and sometimes a guard for the back of the neck. Breathing holes first appear early in the reign of Henry III. It formed a very heavy single structure, sometimes with bands of iron in front constituting a cross; and in the earlier forms the head bore the whole weight; but later it was constructed to rest on the shoulders, and the crossbands disappeared. It was fastened to the saddle-bow when not in use. The movable aventail appears on the second seal of Henry III. An excellent example may be seen on the male effigy in Whitworth Churchyard, which is described in the _Proceedings of the Newcastle-upon-Tyne Society of Antiquaries_, vol. iv., p. 250. This monument shows two recumbent figures--male and female. We are concerned with the male effigy, and have the authority of Mr. Longstaffe that it represented a member of the family of Humez of Brancepeth. The character of the armour would indicate a date in the second quarter of the thirteenth century. The helm is cylindrical and flat-topped. There are two other north-country effigies of about the same date, one at Pittington, the helmet of which is round-topped, and the other at Chester-le-Street (both in the county of Durham). The round-topped helm appeared late in the thirteenth century. A very early thirteenth century helm may be seen on an effigy in Staunton Church, Nottingham, and a flat-topped cylindrical specimen surmounts the figure on the curious water ewer shown in Plate XXII. of _Archæologia Æliana_, vol. iv. (O.S.). There are instances of this form as early as the last quarter of the twelfth century.
