This is the README for the TheanoDidot package, version 2022/09/26. This package provides the TheanoDidot font designed by Alexey Kryukov, in both TrueType and Type1 formats, with support for both traditional and modern LaTeX processors. An artificially-emboldened variant has been provided but there are no italic variants. The package is named after Theano, a famous Ancient Greek woman philosopher, who was first a student of Pythagoras, and supposedly became his wife. The Didot family were active as designers for about 100 years in the 18th and 19th centuries. They were printers, publishers, typeface designers, inventors and intellectuals. Around 1800 the Didot family owned the most important print shop and font foundry in France. Pierre Didot, the printer, published a document with the typefaces of his brother, Firmin Didot, the typeface designer. The strong clear forms of this alphabet display objective, rational characteristics and are representative of the time and philosophy of the Enlightenment. To install this package on a TDS-compliant TeX system download the file "tex-archive"/install/fonts/theanodidot.tds.zip where the preferred URL for "tex-archive" is http://mirrors.ctan.org. Unzip the archive at the root of an appropriate texmf tree, likely a personal or local tree. If necessary, update the file-name database (e.g., texhash). Update the font-map files by enabling the Map file TheanoDidot.map. To use, add \usepackage{TheanoDidot} to the preamble of your document. This will activate TheanoDidot-Regular as the main (serifed) text font. Font encodings supported are OT1, T1, TS1, LY1 and LGR. The default figure style is lining but OldStyle figures may be obtained by using the option osf (or oldstyle) or the command \theanodidotosf. Options scaled= or scale= may be used to scale the fonts. The fonts are licensed under the SIL Open Font License, version 1.1; the text may be found in the doc directory. The type1 versions were created using fontforge. The LaTeX support files were created using autoinst and are licensed under the terms of the LaTeX Project Public License. The maintainer of this package is Bob Tennent (rdt at cs.queensu.ca).
