It is a numeric symbol whose graphical representation does not have either the same height or the same basis as the capital letters; also called the figure not aligned, tiny, low box, text or old style, because it was used since the invention of the printing press until the 19th century; so-called in honour to the Elzevir family or Elzeviro of Louvain, during the 16th and 17TH centuries had with the Church exclusive print religious texts; After a period of disuse during the 19th and 20th centuries, it has become to be used, from the 1980s, especially in texts of history without mathematical function but, above all, chronological.
