GFS Neohellenic is an almost sans serif typeface in style evolved in academic circles in the 19th and 20th century.
The typeface is based on the Greek type New Hellenic, produced by Lanston Monotype Corporation in 1927 in consultation with British Museum Library curator Victor Scholderer. It's the revival of a round, and almost monoline type which had first appeared in 1492 in the edition of Macrobius, ascribable to the printing shop of Giovanni Rosso (Joannes Rubeus) in Venice.
GFS digitized the typeface (1993-1994) funded by the Athens Archeological Society with the addition of a new set of epigraphical symbols. Later (2000) more weights were added (italic, bold and bold italic) as well as a latin version.
