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.
