A one - of - a - variety bark shield date stamp back to the Iron Age has been unearth in England . Archaeologists have never seen anything like it , describing the artifact as “ lose technology . ”
The barque carapace was discovered four yr ago in what was once a farm animal tearing gob , according to areleaseissued by the University of York . Normally , point made from organic materials , such as barque , do n’t keep well , but in this case , the moist , inert conditions prevent the shield from degrade . The bark cuticle is the only one of its sort ever found in Europe , according to a University of Leicesterrelease .
The artefact , called the Enderby shield , was let on by archeologist from the University of Leicester Archaeological Service at the Everards Meadows situation in 2015 , which is south of Leicester , England . This orbit once hosted a vibrant Iron Age farming community . The bark carapace , which was made from either alder , willow , poplar , hazel , or spindle tree diagram , was radiocarbon go out to between 395 and 255 BCE , accordingto the University of Leicester . The outer bed of barque formed the inside of the shield .

archaeologist have previously document the use of bark to manufacture other objects , but this is the first clock time the material has been determine in an Iron Age weapon . This discovery is accordingly changing our concept of the stuff and techniques used to create defensive weapon system K of eld ago .
“ This unfeignedly astonishing and unparalleled artefact has give us an insight into prehistorical technology that we could never have reckon at , ” University of York archeologist Michael Bamforth , who guide the analysis of shield , said in the university ’s press release . “ Although we know that barque has many uses , admit making box seat and containers it does n’t survive well in the archaeological record . ”
The bark buckler measured 67 centimeters ( 26.3 inch ) foresightful and 37 centimeters ( 14.5 column inch ) astray when it was still in the ground , accord to the University of Leicester . The manufacturing business of the shield used wooden laths — slight , flat strips of wood used to organize a base — to stiffen the complex body part . The shield also featured an border rim made of wood , and a woven stud at the center , called a boss , to protect the shield ’s wooden handle .

“ This is a lost technology , ” Matt Beamish , the lead archaeologist from the University of Leicester Archaeological Service , toldthe Guardian . “ It has not been run into before as far as we are cognisant , but presumably it is a technique that was used in many way for make bark items , ” he said .
Analysis indicate that the buckler was once colored in red and adorn with a checkerboard pattern . The cuticle was “ badly damage ” before it ended up in the lacrimation kettle of fish , as mention in the University of York spillage . This damage was likely triggered by spear tips , but the researchers are n’t entirely indisputable .
“ The first time I saw the shield I was utterly awed by it : the complex social organisation , the measured decorations , and the beautiful knob , ” Rachel Crellin , a prof at the University of Leicester who assessed the shell , in the University of York statement .

ab initio , the archaeologists figured the thin bark shield was too flimsy and visionary for use as a defensive weapon , and that it might have or else served a ceremonial purpose . To valuate its functionality , the researchers engaged in some data-based archeology . Using fabric source from the area where the shield was chance and a mere peter kit , they reconstruct the shield from scratch . This utilization offered authoritative brainstorm into how the shield was create — and peradventure how the design may have inspired the more sophisticated metal cuticle that followed .
“ The form of the finish items is fascinating , with differential shrinkage of the wood components induce the shell to curl as they dry . When consider from the front the rectangular cuticle appear ‘ waisted ’ or 60 minutes - trash mold , ” harmonize to the University of Leicester . “ This may be of some significance , as some metal shield from the period of time , such as the Battersea Shield in the British Museum , are like and may be copying the pattern . ”
Tests of the experimental shield showed that it was unclouded , but long-wearing .

“ It was only through experimentation that we realized it could be tough enough to protect against blows from metal artillery , ” according to Bamforth . “ Although a bark shield is not as strong as one made from wood or metal , it would be much scant allowing the user much more exemption of movement . ”
The University of Leicester has donated the shield to the British Museum , and it is scheduled to go on display in 2020 .
