When recently going through the second edition of Nilsson's Geschichte der griechischen Religion, Volume I, I came across a passing remark which seems to me to raise an interesting question not merely of Homeric criticism but concerning the attitude of the Greeks, at the time when their classical tradition regarding the gods was in process of formation, towards the question of the shapes assumed by those gods when they partly reveal themselves to mankind. Nilsson is speaking of Odysseus when disguised as a beggar, and says (ed. 2, p. 370, taken over unaltered from ed. 1, P. 346),
Kirke verwandelt Menschen in Bestien, und Athena den Odysseus in einen alten, armen Mann. Jenes ist echte Volkssage, dieses in Anlehnung daran geschaffen; denn in der älteren Form des Gedichts war Odysseus nicht verwandelt, nur verkleidet. So ist er noch bei der Fusswaschung, und der Freiermord und der Kampf mit Iros (σ 67 ff.) fordern dasselbe.
