Great helm

13th century German great helm with a flat top to the skull.

The great helm or heaume, also called pot helm, bucket helm and barrel helm, is a helmet of the High Middle Ages which arose in the late twelfth century in the context of the Crusades and remained in use until the fourteenth century. They were used by knights and heavy infantry in most European armies between the XIII and XIV centuries.

Great helms were worn with cloth and fiber padding on the inside, here shown removed from the helmet.

In its simplest form, the great helm was a flat-topped cylinder of steel that completely covered the head and had only very small openings for the eyes and mouth. Later designs gained more of a curved design, particularly on the top, to deflect or lessen the impact of blows.

The great helm ultimately evolved from the nasal helmet, which had been produced in a flat-topped variant with a square profile by about 1180.[1] From this type of helmet an intermediate type, called an 'enclosed helmet' or 'primitive great helm', developed near the end of the 12th century. In this helmet the expansion of the nasal produced a full face-plate, pierced for sight and breathing. This helmet was largely superseded by the true great helm by c. 1240.[2]

A later variant with a more conical top is known as a 'sugarloaf helm'. In Spanish they are called yelmo de Zaragoza, referring to Zaragoza where they were introduced for the first time in the Iberian peninsula.[3]

Although the great helm offered vastly superior protection than previous helmets, such as the gorgets were introduced, around 1400.

The bascinet evolved from its early skull cap form to supersede the great helm for combat. The great helm fell into disuse during the 15th century; however it was used commonly in tournaments where a version of the great helm, the frog-mouthed tilting helm, evolved.[4]

The Great Helm was often blackened, lacquered or painted, and frequently bore decorations such as:

  • Ventilation decoration (crosses and symbols)
  • Visor (horizontal and vertical "cross") decorations
  • Crests, such as crowns, feathers, caps of maintenance, wings, lions, etc.

Contemporary reenactors

The great helm is today especially popular amongst live-action role players and in medieval re-enactment such as the Society for Creative Anachronism. It is inexpensive, easy to manufacture with even rudimentary equipment (metal scissors, drill, rudimentary anvil, rivets and hammer), and provides good protection for the head against both sharp and blunt weapons. Its biggest drawbacks are poor ventilation and air circulation, especially if worn with closed-cell foam padding, making it very hot in warm weather.

Modern reenactment versions of great helms weigh 1.5 to 3 kg. For safety reasons, they are made from thicker steel than medieval originals but are not overly heavy, cumbersome, or uncomfortable. Although visor slits are usually only some 20–30 mm wide, they do not greatly restrict the field of vision as they are very close to the wearer's eyes.[5]
