For some years past a collection of helmets and portions of plate armour has been exhibited in the Ethnological Museum at Athens which, in spite of the exceptional interest which attaches to it, has up to the present time escaped the serious consideration of writers on the subject of the defensive armour of the Middle Ages. It is especially interesting because, from the time of the discovery of the collection to the present day, there has not been any attempt to restore or alter the condition in which the pieces were found, and when we consider the frequent mistakes made formerly, in other armouries, in this direction, this alone should recommend it to the study of those interested in mediaeval equipment.
