the sacerdotal laws of sacrifice, purification and others, came to the Hebrews from the example of the Persians.[722] One portion of these ideas has found a place in the Babylonian sections of Genesis—that which belonged to the cosmogony; others were not expressed in the Canon at all, but lived in tradition, until tradition itself was fixed in writing. This question, which would at last shed light on the details of Iranian influence on the narratives of the Pentateuch, is perversely enough not grappled with at its starting-point by many persons who labour with nervous eagerness to discover in the Iranian writings every letter of the Jewish Agâdâ, even in cases in which such a proceeding is utterly unjustifiable, and borrowing can only be suggested through the wildest guesswork. Equally perverse is the unhistorical assumption, which point-blank denies the very possibility of the Hebrews having borrowed anything from the Persians, ‘among whom they never lived.’[723] Professor Spiegel, by referring to an acquaintance of Abraham with Zarathustra, has spirited the question off into the atmosphere of so distant a time that it is impossible with any regard for critical history to build upon his foundation,[724] and preferable even to adopt Volney’s forgotten theory,[725] which makes the influence of Magism on the Hebrews begin with the destruction of the Northern kingdom. Others, by assuming an influence exerted by the Semites on the Iranians, and by a mistaken reverence for Hebrew antiquity, have cut away the ground from any scientific investigation of the question.[726] It is a mistaken, and anything but the right sort of reverence, when we would rather leave unknown or misunderstood a region of literature which we all love and venerate, and to which we owe most of our moral and religious ideals, than trace its elements and analyse their psychological and literary history, so as to understand the object of our love. Has Homer lost his attractiveness since we have subjected him to critical analysis, or the divine Plato forfeited any of his divinity since we have discovered some of the sources of his ideas? For the fact of Originality is not the only criterion of the admirable. Not only that which is cast in one piece from top to toe, is one whole: an alien substance which becomes a civilising agent to that in which it rests, and a patchwork which has turned out a harmonious whole, are not less admirable or perfect. Julius Braun says very justly,[727] ‘There is another and indeed the highest kind of originality, which is not the beginning but the result of historical growth—the originality of mature age. We have this, when an individual or a nation has gathered up all existing means of culture, and then still possesses power to pass on beyond them and deal freely with all elements received from the past.’
