Formats of Early Book: Symbolism, Ill Treatmeant, Initial Size Recalculation

The current study will aim to present several considerations on the formats of codices and early printed books, with special reference to the proportions, the virtual geometrical structure of the page dimensions and the entire surface of the open book. The author proposes herein that such ratios and virtual geometric arrangements are elements of a hidden religious symbolism inherited from antiquity. To support this argument, some codices and early printed books will be indicated that underwent repair works and were re-bonded. Ten material signs by which one could identify any re-binding works will be indicated herein. Supplementary, four methods for recalculating the initial paper size of codices and early printed books, before the trimming of the book block was performed, will be indicated as well.
