bascinet

The bascinet was a Medieval European open-faced military helmet, typically fitted with an aventail and hinged visor. It evolved from the cervelliere.The term is also written as bassinet or basinet. The earliest versions of the bascinet, at the beginning of the 14th century, had no visors, and were worn underneath larger "great helms." After the initial clash of lances, the great helm was often discarded during fierce hand-to-hand combat, as it impeded breathing and vision. Thus, having a smaller helmet underneath was a real advantage. Small "nasals" were developed to protect the nose and part of the face after the great helm was discarded. By the middle of the 14th century, most knights discarded the great helm altogether in favor of a fully visored bascinet. The visor was often conical, giving the appearance of a muzzle or a beak. They were sometimes called "dog faced" (medievally known as a hounskull) or "pig faced" (a common but strictly modern term). The early versions sometimes had a neck defence of mail called a camail or aventail, while later versions (at the end of the 14th century) often protected the neck with a separate but attached plate assembly, the gorget. The aventail was attached to a leather band, which was in turn attached to the lower border of the bascinet by a series of staples called "vervelles". Holes in the leather band were passed over the vervelles, and a waxed cord was passed through the holes in the vervelles to secure it. The helmet also had a series of small holes around the bottom edge of the helmet and the face hole. These holes were used to sew a padded liner inside the helmet. The liner was made of linen or a linen blend cloth stuffed with wool or horsehair. The top of the liner was a series of lobes which were gathered by a cord to adjust how high the helmet rode on the wearer's head. While no known chin straps were used, the bascinet was often prevented from being lifted off the wearer's head by tying or strapping the camail to the surcoat or armour. The bascinet, both with and without a visor (visors were often removable for better visibility and ventilation), was the most common helmet worn in Europe during the latter portions of the 14th and early 15th century, including during the Hundred Years' War. Contemporary illustrations show nearly every knight and man-at-arms wearing one of a few variants of the basic hounskull helmet. The basic design was intended to direct blows from weapons downward and away from the skull and face of the wearer. Over the course of the late 1300s to early 1400s, the bascinet evolved from a shorter form with a shorter point (or no point at all) to its more pointed form--some so severe as to have a vertical back. In Germany a more bulbous version also appeared in the beginning of the 15th century. During the first half of the 15th century, more plates were added to protect the throat better, producing a form called the "great bascinet". Both the portion covering the skull and the hinged visor over the face became less angular and more rounded, until by the mid- to late 1400s, the great bascinet had evolved into the armet.

A light helmet, at first open, but later made with a visor.
  

The helmet that evolved out of the cervellaire , a small "skull cap" worn under the great helm , by extending the plate down over the neck and cheeks. Gradually the great helm was discarded altogether in favor of the bascinet because of the superior vision, glancing surface, and lightweight design. Early bascinets had no visors , but by the second quarter of the 14th century they were fitted with Klappvisiers , visors, using a centralized hinge system. Many of these hinges were easily removed, possibly meaning that they were intended to be discarded after the battle was joined. During the 1370s visors began to be attached to the side of the helmet, a more secure attachment system that often allowed the visor to pivot completely back around the helmet, meaning that it might not be lost in battle. During the 1390s steel ventails gradually replaced the mail aventail that had been fitted alongside the klappvisier to defend the neck , creating a new kind of helmet, the great bascinet , popular especially in the Hundred Years War in both France and England. Many examples can be seen in funery effigies of the period. This innovation of hinged neck defenses gradually evolved into the Armet , the dominant helmet of the 15th century. The bascinet itself was popular throughout Europe during the 14th century, showing a great variety of forms within the style. It is now the most popular helmet in the SCA because of the pronounced glancing surface, ease with which a grille may be attached and interchanged with a visor, superior defense for the head and neck, and sleek appearance.
