The Chinese claims for priority in the practice of block printing have been disallowed by some critics, chiefly because they have been presented in the form of perverted translations. That oriental people practised printing before this art was applied to any useful purpose in Europe is admitted by all who have studied their history. Du Halde, a learned Jesuit father, who traveled in China during the earlier part of the [p110] eighteenth century, was the first author who furnished Europeans with a description of Chinese printing. He quotes the following extract from a Chinese book, supposed to have been written in the reign of the emperor Wu-Wong, who was living 1120 B. C. “As the stone _me_ (Chinese for blacking), which is used to blacken the engraved characters, can never become white, so a heart blackened by vices will always retain its blackness.”[40] This is an allusion to some primitive method of blackening incised characters, for the purpose of making them more legible. It is a method which is still observed in the inscriptions on memorial stones in churches and graveyards. But it is an allusion to engraving and blackening only. There is no mention of printing ink, and no suggestion of printing. Du Halde quoted it only to show the antiquity of engraving, yet it has been used by many authors as a warrant for the assertion that printing was practised in China eleven hundred years before the Christian era. If we could accept this statement, we should have to believe that printing was invented in China but a few years after the siege of Troy, before Rome was founded, before Homer wrote and Solomon reigned. Du Halde’s words do not warrant this statement. He says, with due caution, “In printing, it seemeth that China ought to have the precedence of other nations, for, according to their books, the Chinese have made use of this art for sixteen hundred years,” or since the first century.
