(a) As soon as the first permanent settlements had been established the Jew was suddenly 'there'. He arrived as a merchant and in the beginning did not trouble to disguise his nationality. He still remained openly a Jew, partly it may be because he knew too little of the language. It may also be that people of other races refused to mix with him, so that he could not very well adopt any other appearance than that of a foreign merchant. Because of his subtlety and cunning and the lack of experience on the part of the people whose guest he became, it was not to his disadvantage openly to retain his Jewish character. This may even have been advantageous to him; for the foreigner was received kindly.
