Reconstruction of a Mycaenean armour and weapons. The Mycaenean plate armour is an exact copy of the Dendra armour, presented in Nafplion Archeological Museum. The peculiar bronze double-headed blade is dated around 16th Century BC found at Agios Onoufrios near Phaistos Crete. The helmet is based on depiction from Medinet Habu, Mortuary Temple of Ramesses III, Luxor.
