Spelling variation and text alignment

In the 15th century, at a time when codification via dictionaries and grammars had not yet taken effect, printers, editors, and compositors were already producing pamphlets and books that had to meet the new requirements of the letterpress, especially as regards the arrangement of white space and uniform line justification (even-margined on the left and right). The following analysis investigates five German editions of the Mirabilia Romae (Marvels of the City of Rome), a well-known pilgrim guide, all printed in 1500 for the contemporaneous Jubilee year and thus for short-term sale. The results show that compositors used different means for text alignment: In addition to deviations in line counts and the repositioning of lines, they chose extended or contracted spelling variants, predominantly on the second half of the page. The most frequent variants are abbreviations in the form of tildes. However, just a few spelling patterns with tildes were used. With respect to explanatory processes in a historical perspective, the results call for a closer consideration of page format, text layout (mise-en-page) and line justification when evaluating spelling variation in early book printing.
