_Martins, the Louvain Printer_.--Your correspondent "W." (No.
12. p. 185.) is informed, that in Falkenstein's _Geschichte der
Buchdrucherkunst_ (Leipzig, 1840, p. 257.), Theoderich Martens,
printer in Louvain and Antwerp, is twice mentioned. I have no doubt
but this is the correct German form of the name. Mertens, by which he
was also known, may very possibly be the Flemish form. His Christian
name was also written Dierik, a short form of Dietrich, which, in its
turn, is the same as Theodorich.
