Illyrian type helmet

Preserved opening evidence

Record the surviving opening and cheek profiles as observations, distinguishing original contours from broken or restored edges before using them diagnostically.

1. Which original edges establish the shape of the face opening and the cheek-to-ear junction? definition
2. Could missing nasal protection, displaced cheek-pieces or restoration produce a misleading resemblance to this type? boundary

Crest-track comparison

A British Museum specimen preserves a raised longitudinal track bordered by ridges and possible crest-attachment studs; use this as a documented comparison, not a universal specification. [British Museum specimen](https://www.britishmuseum.org/collection/object/G_1914-0408-1)

1. What track, ridges and attachment traces survive, and which are reconstructed? measurement
2. Which documented comparison supports interpreting the crown and rear profile as this type rather than a neighbouring form? boundary

Shell construction evidence

The British Museum example is described as hammered from a single bronze sheet; establish construction separately for each specimen rather than extending that observation to every proposed subtype. [British Museum specimen](https://www.britishmuseum.org/collection/object/G_1914-0408-1)

1. What seams, continuous metal transitions or working traces support the proposed shell construction? definition
2. Where can shell thickness be measured reliably despite corrosion, coatings or repairs? measurement

Attachment function

Record each hole, stud and surviving residue before assigning it to a crest, lining, fastening, ornament or repair; absent organic components remain unresolved unless evidence supports reconstruction.

1. Which attachment traces have an evidenced function, and which admit competing explanations? definition
2. What evidence supports any proposed crest, lining or fastening material and its association with this helmet? provenance

Independent attributions

Keep the type name separate from cultural attribution: the Metropolitan Museum catalogues an Illyrian type helmet as Greek and Archaic. [Metropolitan Museum specimen](https://www.metmuseum.org/art/collection/search/253482)

1. Which named typology and diagnostic observations support the assigned subtype and date interval? definition
2. Which records independently establish findspot, proposed production location and cultural attribution? provenance

Biographical sequence

Build a qualified sequence from observed traces and context. The British Museum specimen carries a dedication to Olympian Zeus, demonstrating that a votive episode can matter to interpretation without defining the helmet kind. [British Museum specimen](https://www.britishmuseum.org/collection/object/G_1914-0408-1)

1. What evidence distinguishes wear, repair, deliberate alteration and post-depositional damage? provenance
2. Does an inscription or associated deposit establish a dedication or burial episode, and how securely is it linked to this specimen? provenance

Diagnostic fabric integrity

Map cracks, losses, deformation and additions specifically across the facial edges, cheek-pieces, ear junctions and crest track so classification can be reassessed against authentic surviving fabric.

1. Which diagnostic contours consist of original metal, repositioned fragments or modern fills? boundary
2. Which cracks or unstable joins prevent unsupported movement or measurement of the cheek-pieces and crown? action

Evidence-preserving access

Choose examination and support methods around the surviving shell and fittings; document hypothetical crests or interiors separately from observed remains, and do not infer wearable protective performance from ancient classification.

1. Which supported views or non-contact examinations can resolve the identification without loading fragile edges or attachments? action
2. Which elements of a proposed reconstruction are directly evidenced, supported by comparison or conjectural? boundary
