after the hako infection (2004)…
… appeared on Earth.
Globe diameter: 12 cm
In 1901 Joseph Fisher, a Jesuit historian who was conducting research in in the library of Prince Johannes zu Waldburg- Wolfegg in Wolfegg Castle in Württemberg, Germany, discovered the famous large Waldseemueller’s map called Universalis Cosmographia (1507), as part of the Cosmographiae introductio by the German cartographer Martin Waldseemueller (1470–1520). This was the beginning of an intricate and exciting story where one of the protagonists was a small print depicting twelve gores: the first published ready-to-build world globe with, for the first time, the “New World” surrounded by water. And, for the first time, the name America appeared on Earth.
From Wikipedia: Five copies of the globe gores are extant. The first to be rediscovered was found in 1871 and is now in the James Ford Bell Library of the University of Minnesota. Another copy was found inside a Ptolemy atlas and is in the Bavarian State Library in Munich. A third copy was discovered in 1992 bound into an edition of Aristotle in the Stadtbücherei Offenburg, a public library in Germany. A fourth copy came to light in 2003 when its European owner read a newspaper article about the Waldseemüller map. It was sold at auction to Charles Frodsham & Co. for $1,002,267, a world record price for a single sheet map. In July 2012, a statement was released from Ludwig Maximilian University of Munich that a fifth copy of the gores had been found in the LMU Library’s collection which is somewhat different from the other copies, perhaps because of a later date of printing. LMU Library has made an electronic version of their copy of the map available online.
Waldseemueller’s group of cartographers derived the word “America” from the name of Italian explorer Amerigo Vespucci, who was the first to argue that the land mass discovered by Christopher Columbus in 1492 was a new continent, and not part of Asia. Waldseemueller and his fellow scholars used an account of Vespucci’s voyages to draw their new maps. The real merit of Vespucci in the exploration of the New World is still subject of debate, making the story of the Cosmographiae introductio, the large map and the small globe even more fascinating.
You can find a lot of information on Wikipedia, of course. If you are really interested, I suggest to read Toby Lester’s The Fourth Part of the Globe (Free Press, 2009).
Note: The twelve gores I used for this globe design were adapted from the high-res. file (1509 edition) freely downloadable at the Library of Congress website.
The Christmas Ball version of Pardies’ Celestial Globe is now available!
Merry Christmas and a Wonderful 2014!
[diameter of the Celestial Globe: 25 cm]
Visit the David Rumsey Map Collection website to admire and download Pardies’ star and constellation maps. Another great website with a lot of information about Pardies’ masterpiece is Atlas Coelestis (sorry, mostly in Italian…).
If you have already downloaded the Globe project (before Dec. 3), but you are not satisfied by the final result because Pole holes are not well defined, download the Pole Caps for improving your model.
Stay tuned! Christmas Ball version of Pardies Celestial Globe in progress…

The Mechanism. WAP is a paper automaton whose main mechanism is Redtenbacher`s variation of the Cartwright straight-line mechanism, a twin gear driving a common slider crank. If the two gears have different but almost equal number of teeth, the up and down motion of the bar is then an addition and subtraction of two sinusoidal functions. The straight line generation, determined by the vertical motion of the bar, was a very important problem in the early history of mechanics. In WAP, the “random” motion of the unlucky airplane is generated at the center of the beam, that is free to spin. At that point, the two sinusoidal movements originate the oscillation that, together with the up and down motion of the bar, results in the air-pocket-like shaking up.

The main mechanism in WAP is based on two gears with ratio equal to 1.2 (18/15 teeth). The entire cycle is completed after five turns of the handle.
Ferdinand Redtenbacher (1809-1863). The transformation of mechanical technology from a mainly workshop-based profession into an engineering science, particularly in the area of design of machines and mechanisms, is closely related with the name of Ferdinand Redtenbacher. He was of eminent historical importance for the evolution of mechanical engineering to a technical science in the nineteenth century. Redtenbacher’s role as the originator of mechanical engineering as a science in Germany is fundamental and of general interest since the introduction of science into engineering is a “sine qua none” for the development of a powerful high tech industry. As a professor and the director of the Polytechnic School in Karlsruhe, Germany – today the University of Karlsruhe (TH) –, Redtenbacher’s influence therefore helped establish the German manufacturing systems engineering even today. (from Wauer, J., Mauersberger, K., Moon, F. C., 2010. Ferdinand Jakob Redtenbacher (1809–1863), in Distinguished Figures in Mechanism and Machine Science, History of Mechanism and Machine Science, Ceccarelli, M. Ed., Springer Netherlands).
Years ago, paper modellers community was very excited by the so called hako designs, small paper figures mainly made of boxy parts assembled together. There was a bloom of paper hakos, some of them truly exquisite. As many others, I designed some hako models, too.
Dracula was the first one…
Petrus Plancius (Pieter Platevoet, 1552-1622) was a famous Flemish cartographer. He included new constellations in the austral celestial emisphere. In 1612, he drew 12 gores for a 14.5 cm diameter celestial globe, with eight new constellations inspired to the Bible. For the present model, the original gores published in 1649, were downloaded from the Bibliothèque nationale de France website. The colours of the original file were digitally converted in the “nocturnal” version here presented.
Petrus Plancius (Pieter Platevoet, 1552-1622) fu un famoso cartografo fiammingo. Autore di numerosi globi celesti, egli introdusse nuove costellazioni nell’emisfero australe. Nel 1612 disegnò 12 fusi per un piccolo globo celeste del diametro di 14.5 cm, in cui compaiono otto nuove costellazioni ispirate alla Bibbia. Per questo modello, i fusi originali, pubblicati nel 1649, sono quelli scaricabili dal sito web della Bibliothèque nationale de France. Con un semplice processo di ridefinizione della gamma cromatica, i fusi sono stati trasformati nella versione “notturna” qui proposta.
In 1922-23, LA Times newspaper offered to its readers a series of animated cards by Dan Rudolf to cutout and assemble.
Some years ago (maybe in 2007) I downloaded these cards from the Barnacle Press site, a web archive dedicated to vintage comic strip, dating from the turn of the last century.
Since August 2012, after a site crash, the Barnacle Press is recreating part of the image archive that was lost when the site went down. The archive comprises 27 animated cards in the section Papercraft of the Comic Supplement page, but the resolution is now lower than it was in 2007.
Fortunately, recently I have discovered the Christine Nelson Flickr collection with 39 hi-res. LA Times animated cards. So, the fans of these fascinating vintage cards have a wonderful opportunity…
In the meantime, enjoy the colored (by myself) version of the Santa and his favourite Reindeer (Rudolf?… but, what about his red noise?)
Nel periodo 1922-23, il quotidiano Los Angeles Times offrì ai suoi lettori una serie di cartoline animate disegnate da Dan Rudolf da ritagliare ed assemblare.
Alcuni anni fa (forse nel 2007) ho scaricato queste cartoline dal sito Barnacle Press, un archivio web dedicato ai fumetti d’inizio secolo. Dallo scorso agosto, dopo un crash del sito, il Barnacle Press sta ricostituendo parte dell’archivio immagini perduta. L’archivio contiene 27 cartoline animate nella sezione Papercraft della pagina Comic Supplement, ma la risoluzione delle immagini è più bassa di quella del 2007.
Fortunatamente, recentemente ho scoperto la collezione Flickr di Christine Nelson con 39 cartoline animate del Los Angeles Times. Beh, i fan di queste affascinanti cartoline vintage hanno una meravigliosa opportunità…
Nel frattempo, godetevi questa versione colorata (da me) di Babbo Natale con la sua renna preferita (Rudolf?… ma non ha il naso rosso…).
Giovanni Maria Cassini (1745-1824) was regarded as one of the last great Italian globemakers of the 18th century. Here, I present two 15 cm diameter globes in a Christmas ornament version. The larger version of the terrestrial globe was already proposed in my previous post. The celestial globe is a new entry. The hi-res. digital reproduction of the twelve gores and the two polar calottes are available at the wonderful David Rumsey Map Collection website, that is really worth of visiting. The celestial globe gores were published in 1792 in Rome. They were based upon the astronomical observation of Flamsteed and Lacaille, and depict all known constellations with stars varying in size according to their magnitude.
Anothe great web site where you can get a lot of information about this and many other celestial globes and maps is Atlas Coelestis by F. Stoppa. Unfortunately, the site is in Italian only, but the number of wonderful picture is so large that I suggest to visit it.
Giovanni Maria Cassini (1745-1824) è considerato uno degli ultimi grandi costruttori italiani di globi del 18° secolo. In questo post presento due globi da 15 cm di diametro in versione natalizia. Una versione più grande del globo terrestre è stata già presentata nel post precedente; il globo celeste è una new entry. Le riproduzioni digitali ad alta risoluzione dei dodici fusi e delle due calotte polari sono scaricabili dal meraviglioso sito web della David Rumsey Map Collection, che vale veramente la pena di visitare.
I fusi per il globo celeste vennero pubblicati a Roma nel 1792. Essi sono basati sulle osservazioni astronomiche di Flamsteed e Lacaille, e raffigurano tutte le costellazioni allora conosciute con stelle di grandezza variabile a seconda della loro magnitudo.
Un altro imperdibile sito web pieno di informazioni su questo e molti altri globi e mappe celesti è l’Atlas Coelestis di F. Stoppa.
