Hi Dan/Nick
Sorry I have should have been more specific, the warrior that I quoted appears in British Library MS Cotton Cleopatra C.V111 and this 'garment' is often referred to as representing
mail armour which may be fair comment as he is armed with
shield and spear, however he also wears the forward curled crested style head wear which in its self is problematic.
It is often thought that such caps are an artistic convention of using earlier 'Classical' styles as a model, and this may possibly be echoed in the vandyking of his sleeves and hem of this mentioned 'armour' , perhaps also representing thef earlier Roman/Byzantine armour model.
His 'underclothing' follows the traditional Anglo-Saxon manuscript representation of long sleeved tunics of the period.
Having said the latter I can not think of any other vandyked representation of civilian garment, Anglo-Saxon, or Viking, whose iconography of clothing and armour always appears to generate polarization of opinion!
