Note 218 — XIX
Reading edition
For this unwarrantable confusion of the names and deeds of the two men Junius and Scriverius are responsible. Junius, who wrote in Latin, caught at the word Coster, which he found in the pedigree, as a subject for the display of his critical ability. He explains and expounds it: “Lourens Janszoon, surnamed Coster, by reason of the office which belonged to the family by hereditary right.” There was no need for this absurd expansion of the meaning of the word custos. This attribution of an honorable office to an insignificant man was purposely made to give him a dignified position. Gerrit Thomaszoon, who knew that Coster was a man of no note, gave him only the distinction of the first printer. This was not enough for Junius, who thought that he would be deficient in patriotism if he did not make Coster as reputable as his rival Gutenberg, who was represented as of noble blood. The word Coster was his opportunity, and he made the most of it. It is not probable that Junius studied the archives of Haarlem for the purpose of getting exact information about Coster, but it is possible that he had read or heard of Lourens Janszoon, the wealthy man, and that he confounded him with Coster, the chandler. Whether he made this confusion with intent or in ignorance cannot now be ascertained, but we can see that the wealth and respectability of Janszoon were attributed to Coster. Scriverius perpetuated the blunder. He found a document signed by Louwerijs Janszoon, as sheriff, in 1431. Without further research, he leaped to the conclusion that this man who died in 1439, who had nothing in common with Coster but similarity of name and similarity of occupation as innkeeper, was the very Lourens Janszoon Coster who, according to Junius, invented types and practised printing in 1440.
