  • Notes

    Philippe Danfrie (c. 1532-1606) was born in Brittany and moved to Paris in his twenties, where he became a partner in a printing and bookselling business. He designed a new typeface in cursive script, which was given the name of "caractère de civilité". He later studied mathematics, became an "ingénieur", and was appointed Royal die cutter for coins of the realm. Danfrie took a special interest in inexpensive alternatives to brass instruments. he is known for some 20 mathematical instruments, notably his astrolabes printed on paper, and for his invention of the graphomètre, on which he published in 1597.

    We are only aware of five other surviving Danfrie paper astrolabes: one dated 1578, incomplete (missing one of the seven plates [with brass rete]) sold at Christie's South Kensington in 1998; another dated 1578 belongs to the Service hydrographique de la Marine; one dated 1584 described by tesseract; another dated 1584 belongs to the Museum of the history of Science oxford; a further 1584 at the national Museum of American history, Smithsonian Institution, Washington DC.
