It is part of a project to provide fonts +% covering the major manuscript hands between the first century~\AD{} and +% the invention of printing. The principal resources used in this project +% are listed in the Bibliography. +% +% This manual is typeset according to the conventions of the +% \LaTeX{} \textsc{docstrip} utility which enables the automatic +% extraction of the \LaTeX{} macro source files~\cite{GOOSSENS94}. +% The \Lpack{docmfp} package is used for documenting the Metafont portions +% of the distribution~\cite{DOCMFP}. +% +% Section~\ref{sec:usc} describes the usage of the package. +% Commented code for the fonts is in Sections~\ref{sec:mf} and~\ref{sec:fd} +% and source code for the package is in Section~\ref{sec:code}. +% +% \subsection{Manuscript book-hands} +% +% Before the invention of printing all books were written by hand. The book-hands +% used by the scribes and copyists for the manuscripts changed as time +% went on. Table~\ref{tab:1} lists some of the common book-hands which were used +% between the 1st and 15th centuries. The later book-hands formed the basis of the +% fonts used by the early printers, which in turn form the basis of the printing +% fonts in use today. +% +% The manuscript book-hands were written with a broad nibbed reed or quill +% pen. Among the distinguishing characteristics of a hand, apart from the +% actual shape of the letters, are the angle of the pen (which controls the +% variation between thick and thin strokes) and the height of a letter compared +% to the width of the nib. The lower the ratio of the letter height to nib +% width, the more condensed is the script. The scripts also varied in their +% typical height. +% +% Table~\ref{tab:1} gives an `average' x-height for each +% script, which I obtained by measuring a sample of photographs of +% manuscripts written in the various hands. About a dozen examples +% of each book-hand were measured. This figure should not be taken too +% seriously. +% +% There was not a sharp division between the use of one hand and another. +% Many manuscripts exhibit a variety of hands in the same document. For example, +% the scribe writing in an Uncial hand may have used Roman Rustic letters +% for capitals. Usually the same pen was used for the two different scripts. +% +% Generally speaking, as a hand got older it became more embelished, and +% therefore took longer to write. As this happened a new hand would appear that +% was faster, and which would eventually make the earlier one obsolete. +% +% Many of the book-hands were single-cased; that is, they did not have an +% upper- and lower-case as we do nowadays in Western scripts. On the other +% hand, a script might be majuscule or minuscule. A \textit{majuscule} script +% is one, like our upper-case, where the letters are drawn between two lines +% and are of a uniform height with no ascenders or descenders. +% A \textit{minuscule} script, like our lower-case, is drawn between four lines +% and has ascenders and descenders. +% +% \begin{table} +% \centering +% \caption{The main manuscript book-hands} \label{tab:1} +% \begin{tabular}{lccccc} \hline +% Name & Century & x-height & Height & Pen & Normalised \\ +% & & (mm) & (nib widths) & angle & height \\ \hline +% Roman Rustic & 1--6 & 5.7 & 4--6 & 45 & 1.90 \\ +% Uncial & 3--6 & 4.1 & 4--5 & 30 & 1.37 \\ +% Half Uncial & 3--9 & 3.2 & 3--6 & 20--30 & 1.07 \\ +% Artificial Uncial & 6--10 & 4.2 & 3--6 & 10 & 1.40 \\ +% Insular majuscule & 6--9 & 4.2 & 5 & 0--20 & 1.40 \\ +% Insular minuscule & 6 onward & 4.1 & 5--6 & 45--70 & 1.37 \\ +% Carolingian minuscule & 8--12 & 3.0 & 3--5 & 45 & 1.00 \\ +% Early Gothic & 11--12 & 3.8 & 4--6 & 20--45 & 1.27 \\ +% Gothic Textura & 13--15 & 3.9 & 3--5 & 30--45 & 1.30 \\ +% Gothic Prescius & 13 onward & 3.3 & 4--5 & 45 & 1.10 \\ +% Rotunda & 13--15 & 3.2 & 4--6 & 30 & 1.07 \\ +% Humanist minuscule & 14 onward & 3.0 & 4--5 & 30--40 & 1.00 \\ \hline +% \end{tabular} +% \end{table} +% +% During the period under consideration arabic numerals were effectively +% not used. At the beginning they were unknown and even though some knew +% of them towards the end, the glyphs used for them are not recognisable --- +% to me they look somewhat like cryllic letters --- and each locality +% and time had its own highly individualistic rendering. The general rule +% when using one of these book-hands is to write all numbers using +% roman numerals. +% +% The Roman alphabet consisted of 23 capital letters --- the J, U and W +% were absent. The book-hands initially used both a `u' and a `v' interchangeably +% but by the 10th century the practice had become to use the `v' before a vowel +% and the `u' otherwise. The letter corresponding to the W sound appeared +% in England around the 7th century in +% the form of the runic \textit{wen} character and by about the 11th century +% the `w' chacter was generally used. The `J' is the newest letter of all, not +% appearing until about the mid 16th century. +% +% In the first century punctuation was virtually unknown, and typically +% would not even be any additional space between individual words, never +% mind denoting ends of sentences. Sometimes a dot at mid-height would be +% used as a word seperator, or to mark off the end of a paragraph. Effectively +% a text was a continuous stream of letters. By the time that printing was +% invented, though, all of our modern punctuation marks were being used. +% +% Among all these manuscript hands, the Carolingian minuscule is the +% most important as our modern fonts are based on its letter shapes, and it is +% also at this point in time where the division occured between the black letter +% scripts as used even today in Germany, and the lighter fonts used elesewhere. +% The Rotunda and Humanist minuscule hands were developed in Italy and were +% essentially a rediscovery of the Carolingian minusucle. Guthenberg took the +% Gothic scripts as the model for his types. Later printers, +% such as Nicholas Jenson of Venice, +% took the Humanist scripts as their models. +% +% +% \subsection{The \thisfont{} script} +% +% With the Gothic hands, used from the thirteenth century, the attention of +% the scribes moved from the individual letter to the word. The scripts +% changed to accomodate this interest so the appearance of the letters +% became subordinate to the overall appearance of the words they formed. +% Many of the letters appear to be indistinguishable today but the contemporary +% reading public seemed to have no difficulty. +% +% It was during the heyday of the Gothic scripts that separate capital +% letters were introduced. Also, as a small concession to legibility, +% the lowecase `i' acquired a small mark above it. Ligatures were similar +% to those in Early Gothic. The letter `w' was added to the hand early on +% and `j' started to appear after 1400, providing the full 26 letter alphabet +% for the first time. +% +% This font includes both lowercase and (fancy) uppercase letters. Guthenberg +% used this script as a model. +% +% \section{The \Lpack{tgothic} and \Lpack{alltgoth} packages} \label{sec:usc} +% +% The \thisfont{} font family is called |tgoth|. The font is supplied in both +% OT1 and T1 encodings. +% +% \subsection{The \Lpack{tgothic} package} +% +% This is intended for the occasions when some short pieces of text have +% to be written in \thisfont{} while the majority of the document is in another +% font. The normal baselineskips are used. +% +% \DescribeMacro{\tgothfamily} +% The |\tgothfamily| declaration starts typesetting with the \thisfont{} fonts. +% Use of the \thisfont{} font will continue until either there is another |\...family| +% declaration or the current group (e.g., environment) is closed. +% +% \DescribeMacro{\texttgoth} +% The command |\texttgoth{|\meta{text}|}| will typeset \meta{text} using the +% \thisfont{} fonts. +% +% \subsection{The \Lpack{alltgoth} package} +% +% +% This package is for when the entire document will be typeset with the +% \thisfont{} font. The baselineskips are set to those appropriate to the +% book-hand. +% +% This is a minimalist package. Apart from declaring \thisfont{} to be the +% default font and setting the baselineskips appropriately, it makes no other +% alterations. +% Vertical spacing +% before and after section titles and before and after lists, etc., will be +% too small as the \LaTeX{} design assumes a font comparable in size to +% normal printing fonts, and the book-hand is much taller. +% To capture more of the flavour of the time, all numbers +% should be written using roman numerals. +% The \Lpack{romannum} package~\cite{ROMANNUM} +% can be used so that \LaTeX{} will typeset the numbers that it generates, +% like sectioning or caption numbers, using roman numerals instead of arabic +% digits. +% +% \DescribeMacro{\cmrfamily} +% \DescribeMacro{\textcmr} +% \DescribeMacro{\cmssfamily} +% \DescribeMacro{\textcmss} +% \DescribeMacro{\cmttfamily} +% \DescribeMacro{\textcmtt} +% The |...family| declarations start typesetting with the Computer Modern Roman +% (|\cmrfamily|), the Computer Modern Sans (|\cmssfamily|), and the Computer +% Modern Typewriter (|\cmttfamily|) font families. The |\textcm..{|\meta{text}|}| +% commands will typeset \meta{text} in the corresponding Computer Modern font. +% +% The \Lpack{alltgoth} package automatically loads the \Lpack{tgothic} package, +% so its font commands are available if necessary. +% +% \StopEventually{ +% \bibliographystyle{alpha} +% \renewcommand{\refname}{Bibliography} +% \begin{thebibliography}{GMS94} +% \addcontentsline{toc}{section}{\refname} +% +% \bibitem[And69]{ANDERSON69} +% Donald M.~Anderson. +% \newblock {\em The Art of Written Forms: The Theory and Practice of Calligraphy}. +% \newblock Holt, Rinehart and Winston, 1969. +% +% \bibitem[Bol95]{BOLOGNA95} +% Giulia Bologna. +% \newblock {\em Illuminated Manuscripts: The Book before Gutenberg}. +% \newblock Crescent Books, 1995. +% +% \bibitem[Day95]{DAY95} +% Lewis F.~Day. +% \newblock {\em Alphabets Old \& New}. +% \newblock (3rd edition originally published by B.~T.~Batsford, 1910) +% \newblock Senate, 1995. +% +% \bibitem[Dro80]{DROGIN80} +% Marc Drogin. +% \newblock {\em Medieval Calligraphy: Its History and Technique}. +% \newblock Allenheld, Osmun \& Co., 1980. +% +% \bibitem[Dru95]{DRUCKER95} +% Johanna Drucker. +% \newblock {\em The Alphabetic Labyrinth}. +% \newblock Thames \& Hudson, 1995. +% +% \bibitem[Fir93]{FIRMAGE93} +% Richard A.~Firmage. +% \newblock {\em The Alphabet Abecedarium}. +% \newblock David R~Goodine, 1993. +% +% \bibitem[Fli98]{LETTRINE} +% Daniel Flipo. +% \newblock {\em The LETTRINE package}. +% \newblock (Available from CTAN in \texttt{macros/latex/contrib/supported}). +% \newblock 1998. +% +% \bibitem[Har95]{HARRIS95} +% David Harris. +% \newblock {\em The Art of Calligraphy}. +% \newblock DK Publishing, 1995. +% +% \bibitem[Jen95]{BETON} +% Frank Jensen. +% \newblock {\em The BETON package}. +% \newblock (Available from CTAN in \texttt{macros/latex/contrib/supported}). +% \newblock 1995. +% +% \bibitem[Joh71]{JOHNSTON75} +% Edward Johnston (ed.

As such, one of the +% aims is to produce a coordinated set of fonts, especially as multiple +% hands might be used in a single document. +% +% Noting that the hands tend to be somewhat larger than the typical 10pt +% size (where the x-height is approximately 1.5mm) used for modern books, +% I have also designed the fonts +% at a larger than normal size, then applied some non-linear factors when reducing +% them down to a 10pt size. +% Further, I have used the height of the Carolingian minuscule as a +% normalising factor when deciding on the absolute height of any particular +% script. The x-height of the Carolingian font is made equal to the +% x-height of the Computer Modern Roman (CMR) font. +% +% Modern fonts are effectively drawn. That is, the outline of the letter is +% drawn carefully and the center is filled with ink. This is shown to good +% effect in the Metafont code for the Computer Modern fonts~\cite{CM}. +% In contrast, the manuscript letters were inked by single pen strokes in +% a calligraphic manner. I have tried to repeat this calligraphic style +% in the Metafont code. +% +% As much as possible I have tried to use parameter values from the +% Computer Modern Roman (CMR) fonts in order to reduce possible +% infelicities if the CM and manuscript fonts are used together. However, +% few of the CMR parameters are applicable to the calligraphic style. +% +% +% \subsection{The parameter file} +% +% We deal with the parameter files first, and start by announcing +% what they are for. The \thisfont{} font comes in three sizes and also as a normal +% and a bold font. +% \begin{macrocode} +%<*base7|base10|base17|base7b|base10b|base17b> +%<base7>%%% TGOTH7.MF Gothic Textura Quadrata at 7 point design size. +%<base10>%%% TGOTH10.MF Gothic Textura Quadrata at 10 point design size. +%<base17>%%% TGOTH17.MF Gothic Textura Quadrata at 17 point design size. +%<base7b>%%% TGOTHB7.MF Gothic Textura Quadrata Bold at 7 point design size. +%<base10b>%%% TGOTHB10.MF Gothic Textura Quadrata Bold at 10 point design size. +%<base17b>%%% TGOTHB17.MF Gothic Textura Quadrata Bold at 17 point design size. +% +% \end{macrocode} +% Parameters from CMR are used as much as possible.
