The objects which form the subject of the present paper, and which may be easily identified by the accompanying cuts, Nos. 5—8, have for some time been a puzzle to students of Mycenaean archaeology. Certain specimens exhibited in the cases of the Mycenae Room in the Polytechnic Museum at Athens are described as ‘objects of unknown use’; and although some suggestions have been thrown out in various publications of isolated examples, I do not think any satisfactory explanation of them has yet been offered. The cause of this failure seems to be the impossibility of understanding properly any such specimen, apart from the whole class to which it belongs. I will therefore begin this paper with a list of instances which, while not pretending to be exhaustive, is at least representative, and so will give some notion of the character, size, shape, and material of the objects now before us.
