flat axe (decoration) |

Description |
English: Cast copper alloy developed flat axe with a crescentic blade and the beginnings of a stop ridge, creating a slightly biconical profile, and dating from the Early Bronze Age. Both faces of the axe are decorated with multiple straight lines punched into the axe after casting, on average about 6 mm in length, and about 1 mm apart, in what is referred to as a 'rain pattern'. The decoration covers an area between the stop ridge, which is 70 mm from the edge of the blade, and about 20 mm from where the blade chamfers and angles down towards the cutting edge, which is about 18 mm in depth. The cutting edge is asymmetrically worn, suggesting extensive use, and the material displacement on one side represents damage from use (Matt Knight pers comm). The corners of the crescentic blade are at right angles to the side of the axe. The surface patina of the axe is good with little evidence of corrosion and the axe has been treated and lacquered and is now stable. Flat axes decorated with this 'rain pattern' and with crescentic blades can be found during the Willerby metalwork phase, dating from c.1875-1725 BC (Roberts et al, 2013, 23, fig.2.2) of the Early Bronze Age, such as the Class 4 axe illustrated in 'The Circulation of Metal in the British Bronze Age: The Application of Lead Isotope Analysis' (Rohl & Needham 1998, 125, fig.26, no.53).
Schmidt & Burgess (1981) also illustrate developed flat axes with crecentic bades and similar 'rain-pattern' decoration from Ryal and Keighley in plates 28-29, nos.329 & 340, which are classified, respectively, as a Type Falkland developed flat axe, which is compared to an axe from Mount Pleasant in Dorset, dated to c.1900 BC, and a Type Scrabo Hill which is associated with similar axes in the Willerby Wold hoards from East Yorkshire, illustrated in plate 134, nos.D1 & D4. |
