The bascinet – also bassinet, basinet, basnet, bacinet, or bazineto – was a Medieval European open-faced combat helmet. It evolved from a type of iron or steel skullcap, but had a more pointed apex to the skull, and it extended downwards at the rear and sides to afford protection for the neck. A mail curtain (aventail or camail) was usually attached to the lower edge of the helmet to protect the throat, neck and shoulders. A visor (face guard) was often employed from c. 1330 to protect the exposed face. Early in the fifteenth century, the camail began to be replaced by a plate metal gorget, giving rise to the so-called "great bascinet".

Early development

The first recorded reference to a bascinet, or bazineto, was in the Italian city of Padua in 1281, when it is described as being worn by infantry.

It is believed that the bascinet evolved from a simple iron skullcap, known as the cervelliere, which was worn with a mail coif, as either the sole form of head protection or beneath a great helm. The bascinet is differentiated from the cervelliere by having a higher, pointed skull. The bascinet appeared quite suddenly in the later 13th century and some authorities see it as being influenced by Byzantine or Middle-Eastern Muslim helmets.

Protection for the throat, neck and face

Camails or aventails

Unlike the cervelliere, which was worn in conjunction with, often underneath, a complete hood of mail called the coif, early bascinets were typically worn with a neck and throat defence of mail that was attached to the lower edge of the helmet itself; this mail "curtain" was called a camail or aventail. The earliest camails were riveted directly to the edge of the helmet, however, beginning in the 1320s a detachable version replaced this type. The detachable 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.

Bretache

This illustration shows a bascinet with a type of detachable nasal (nose protector) called the bretache or bretèche made of sheet metal. The bretache was attached to the aventail at the chin, and it fastened to a hook or clamp on the brow of the helmet. The bretache was also used in Italy; one of the first representations of it is on the equestrian statue of Cangrande I della Scala, who died in 1329. It is also shown on the tomb of Bernardino dei Baranzoni in the Museo Lapidario Estense in Modena, created c. 1345–50. An advantage of the bretache was that it could be worn under a great helm, but afforded some facial protection when the great helm was taken off. Use of the bretache preceded and overlapped with that of a new type of visor used with the bascinet, the "klappvisor" or "klappvisier".

Visored bascinets

The open-faced bascinet, even with the mail aventail, still left the exposed face vulnerable. However, from about 1330, the bascinet was often worn with a "face guard" or movable visor. The klappvisor has been characterised as being intermediate between the bretache nasal and the side pivoting visor. Sources disagree on the nature of the klappvisier. A minority, including De Vries and Smith, class all smaller visors, those that only cover the area of the face left exposed by the aventail, as klappvisiers, regardless of the construction of their hinge mechanism. However, they agree that klappvisiers, by their alternative definition of 'being of small size', preceded the larger forms of visor, which almost exclusively employed the double pivot, found in the latter part of the 14th century.

The side-pivot mount, which used two pivots – one on each side of the helmet, is shown in funerary monuments and other pictorial or sculptural sources of the 1340s. One of the early depictions of a doubly pivoted visor on a bascinet is the funerary monument of Sir Hugh Hastings (d. 1347) in St. Mary's Church, Elsing, Norfolk, England.

Later evolution of the helmet

Between c. 1390 and 1410 the bascinet had an exaggeratedly tall skull with an acutely pointed profile – sometimes so severe as to have a near-vertical back. Ten years later both the skull of the helmet and the hinged visor started to become less angular and more rounded. Almost globular forms became common by c. 1450. As part of the same process the helmet became more close-fitting, and narrowed to follow the contours of the neck.

Bevors and gorgets

Around 1350, during the reign of John II, French bascinets began to be fitted with a hinged chin- or jaw-piece (bevor (sense 2), ), upon which the visor would be able to rest.

The bascinet fitted with a camail was relatively heavy and most of the weight was supported directly by the head. Plate gorgets were introduced from c. 1400–1410, which replaced the camail and moved the weight of the throat and neck defences from the head to the shoulders. At the same time a plate covering the cheeks and lower face was introduced also called the bavière (contemporary usage was not precise). This bavière was directly attached by rivets to the skull of the bascinet. The combined skull and bavière could rotate within the upper part of the gorget, which overlapped them. A degree of freedom of movement was retained, but was probably less than had been the case with the mail camail.

Great bascinet

In the view of Oakeshott the replacement of the camail by a plate gorget gave rise to the form of helmet known as the "great bascinet".

Early gorgets were wide, copying the shape of the earlier aventail, however, with the narrowing of the neck opening the gorget plates had to be hinged to allow the helmet to be put on. Early great bascinets had the skull of the helmet riveted to the rear gorget plate, however, some later great bascinets had the skull forged in a single piece with the rear gorget plate. The gorget was often strapped to both the breast and backplate of the cuirass. However, Henry V of England is reputed to have worn a great helm over a bascinet at the Battle of Agincourt in 1415. He was recorded as receiving a blow to the head during the battle, which damaged his helmet; the double protection afforded by wearing two helmets may have saved his life.

Later use

By the middle of the 14th century, most knights had discarded the great helm altogether in favor of a fully visored bascinet. The bascinet, both with and without a visor, was the most common helmet worn in Europe during most of the 14th century and the first half of the 15th century, including during the Hundred Years' War. Contemporary illustrations show a majority of knights and men-at-arms wearing one of a few variants of the bascinet helmet. Indeed, so ubiquitous was the use of the helmet that "bascinet" became an alternative term for a man-at-arms.

The basic design of the earlier, conical version of the helmet was intended to direct blows from weapons downward and away from the skull and face of the wearer. Later versions of the bascinet, especially the great bascinet, were designed to maximise coverage and therefore protection. In achieving this they sacrificed the mobility and comfort of the wearer; thus, ironically, returning to the situation that the wearers of the cumbersome great helm experienced and that the early bascinets were designed to overcome. It is thought that poorer men-at-arms continued to employ lighter bascinets with mail camails long after the richest had adopted plate gorgets.

Decline in use

Soon after 1450 the "great bascinet" was rapidly discarded for field use, being replaced by the armet and sallet, which were lighter helmets allowing greater freedom of movement for the wearer. However, a version of the great bascinet, usually with a cage-like visor, remained in use for foot combat in tournaments into the 16th century.
