Conrady [15] believed that he had found the common source of the canonical history of the infancy in the so-called "Protevangelium Jacobi", which, according to him, was written in Hebrew by an Egyptian Jew about AD 120, and was soon after translated into Greek; it should be kept in mind, however, that the Greek text is not a translation, but the original, and a mere compilation from the canonical Gospels.

conrady [ 15 ]认为他已经找到了共同的来源，典型的历史，以及起步阶段，在所谓的" protevangelium雅可比"，其中，根据他的说法，写于希伯来语一名埃及犹太人大约公元120 ，并很快就被经过翻译成希腊文，它应该铭刻在脑海里，但是，在希腊文是不是一个翻译，但原，并简单地汇编，从典型福音。
