Infine, vi ricordo che la rivista farà il suo ingresso in tipografia sicuramente dal numero 4 (settembre 1999) in poi. Per l'imminente numero 3 non so se si farà in tempo, ci stiamo provando... Potrebbe essere causa di un ritardo, stavolta però ben giustificato! NOTA INFORMATIVA SULLE PRIME CONDIZIONI GENERALI DI ABBONAMENTO ALLA RIVISTA "GNOMONICA", ORGANO UFFICIALE DELLA SEZIONE QUADRANTI SOLARI DELL'UNIONE ASTROFILI ITALIANI. Cari amici, Sono lieto di farvi conoscere le condizioni proposte dalla Sezione Quadranti Solari dell'UAI relative alle modalità di abbonamento alla rivista "Gnomonica". 1) La rivista "Gnomonica" viene spedita gratuitamente a tutti i soci UAI che desiderano riceverla, non come supplemento di Astronomia, ma come spedizione postale separata; inoltre, su Astronomia, e sul n. 3 di Gnomonica, viene proposto il "pacchetto gnomonico" e cioè l'iscrizione all'UAI comporta il ricevimento della rivista Astronomia + Almanacco Astronomico UAI + Gnomonica + iscrizione gratuita al Seminario + Atti gratuiti del Seminario. La quota sociale per l'iscrizione all'UAI è di lire 60.000 da versare come indicato al punto 2) specificando chiaramente nella causale " ABBONAMENTO A GNOMONICA + PACCHETTO GNOMONICO" 2) Ai non soci UAI la rivista viene offerta a un costo di abbonamento annuale (tre numeri) di 20 000 lire, che devono essere versate sul CCP dell'UAI, N° 11531357 intestato a Unione Astrofili Italiani, Vic. Osservatorio, 5 - 35122 Padova, specificando chiaramente il proprio indirizzo e la causale. 3) Coloro che hanno già versato le quote di abbonamento in precedenza, saranno considerati abbonati a Gnomonica fino alla pubblicazione del n° 3 (compreso). E dovranno rinnovare l'abbonamento dopo la pubblicazione del n° 3 (maggio 1999) che sarà valido da Settembre-99, Maggio-2000. ++ Testo approvato da Gabriele Vanin, presidente dell'UAI, il 19 aprile 1999. Personalmente posso solo dire: "a voi la scelta", ed aggiungere che a mio parere il "pacchetto gnomonico" è di gran lunga la migliore "offerta gnomonica" non solo in Italia, ma anche rispetto a ciò che offrono tutte le altre associazioni gnomoniche straniere. Importante: chi è già socio UAI non deve fare nulla, ma solo verificare che la sua iscrizione non sia scaduta. Deve però scrivere all'Uai, all'indirizzo specificato al n. 2) precedente, e specificare che desidera ricevere il pacchetto gnomonico. Al rinnovo della quota sociale, sul C/C dell'UAI, dovrà specificare la causale: desidero ricevere il pacchetto gnomonico. La redazione di Gnomonica Nicola Severino Importante: invito tutti, da oggi, a scrivermi al seguente nuovo indirizzo: Geom.

Re: Firenze clock
I wish to do my thanks to Frank King for writing my paper about the Italian Hours in the clocks. I was the first author, on 1990, to show the real "secret" of the mechanical clock with only I- and/or I-IV roman numeration of hours. The quadrant of Paolo Uccello in Firenze is the origin of this method. It shown the first mechanical clocks for the italian hours with a inverse numeration from 1 to 24. Thankf to Frsnk for remember my paper and my web page about this.

mosaic sundial
Dear Gianni, thanks for your observations and links. The mosaic sundial of Valentino falcone is unique in the world because him used not a industrial tile, but building himself the tiles (around 25,000 tiles) of 8 millimeter. The mosaic sundial linked from you, only 1-2 is simil at mosaic method, but its are made with a not "very mosaic" art! Best wishes Nicola

It is only for a nice satisfaction for me to divulg this, because (like you all) I love the gnomonica searchs and I do this not for some profit.The technical informations about CD you can read from past message from Fred Sawyer.I have encloused in my CD only two sites from Greace: Delos and tenos because only sundials from this sites I was able to found in the gnomonic documents.I visited my self the archaeological sites and the sundials from:Rome, Pompei, ErcolanoTha CD-R contain a lot of nice images I done in digital quality. You can see the more beautifull images of roman sundials ever seen in the world!Besides, you can read a lot od rare ancient historical documents about this topic, from Woepcke to Deonna.I was in contact with Sharon Gibbs. She was very surprised, glad and satisfacted of my searchs about this topic and I have had the persime to use much material from his book. As, you can see also files and photos from his book.Other announcements and informations you can see on my web pages atwww.nicolaseverino.it in the next days.Thanks for attention and the best wishes to all.Nicola Severino
The sundial of Emperor Augustus - english translation
Dear Friends, I send this translation of my message about the Augustus sundial article of Maes. Hope it is now more easy to read. transalation by Jeck Aubert. Thanks to Jack and thanks to your all. Nicola Severino Translation: In paying my compliments to Frans W Maes for the full and interesting article titled "The Sundail of Emperor Augustus: Rise and Decline of a Hypothesis" appearing in the NASS publication Compendium Volume 12, n. 3 of Septembner 2005, I would like to express my opinion and comment on this investigation. The article appears to be very complete, a full 15 pages out of the total 40 pages of the review. It is rich from the point of view of historical and documentary research and suggests a number of hypotheses and conclusions. First, I would like to note that I am not completely convinced that the oblelisk of Caesar Augustus in the Field of Mars, today visible in the Plaza Montecitorio, really represented in its time the upright gnomon of a complete monumental sundial. The trace of a sundial of these dimensions, in effect, would not provide an effective display of time from the point of view of a human being who passed by but rather would have to haave been "read" from the perspective of a bird skimming above it at a certain height. ("so large that the time would only have been readable from a bird's eye perspective" according to the Maes article.). Nobody however, has been able to demonstrate the contrary, that is to say that the Emperor Augustus had wanted to build a sundial of these demensions because it could be read not from the site but from the many nearby hills of Rome. Certainly this is a hypothesis of suggestive of what a megalomaniac like he might have wanted. I do not understand why the article uses the title "decline of a hypothesis" when this conlusion is not supported by incontrovertable proof that might lead to such an affirmation. There is a consideration of Girolamo Fantoni in his article "The meridian of Augustus" in Clocks, the measure of time, Technimedia, Rome, n. 10, 1988 page 107 where he says: "In effect, it is very probable that the layout of the sundial of Augustus was such that the shadow of the ball that surmounted the obelisk, which symbolized August, the Sun Apollo, touched the Alter of Peace at a given moment to confirm that Aubusuts was born for peace. In fact, these altars [?] designated the equinoctal line that coincided with the date of birth of the emperor, September 23. Furthermore, the axis traced from the obelisk to the alter of peace made a right angle with that of the obelisk of the mausoleum of Augustus. " Fantoni, in turn, took his point of departure from Dosi-Schnell in Space and Time, editions Quasar, Rome 1992. This perfect coincedence of topography of the Field of Mars is called into question by Maes only as the forth conclusion at the end of the article, but on the basis of what? The hypothesis of Fantoni seems to me much more probable. The fans of Athanasius Kircher, who was not at all bad as a gnomonist... can follow his alternative hypothesis that the sundial of Augustus was not only a meridian line but actually traced out a sundial complete with declination curves, etc. The fact that these cannot be found because it is impossible to excavate the subsoil of modern Rome for such an investigation (except for the unique and fortuitous discovery of Buchner), does not seem to allow the preponderance of weight to lead to either one or the other of the hypotheses. The historical documentation is not sufficiently clear and complete to draw definitive conclusions. Finally, I am once more disturbed by the evidence that Italian research and publication always seems to be in last place in the international panorama, and it seems to me indeed strange that such a carefully reseached documentary investigation missed the unique work in the Italian language, and in the world that deals in depth with the history of this obelisk, that is to say, my book "History of the Obelisk and Sundial of Caesar Augustus in the Field of Mars." written in 1996 and published in 1997 which consists of 69 pages and in which I analyze for the first time the history of this obelisk-dial through the most important documents published at that point, and where for the first time was presented an analysis of historic texts through some coded manuscripts of Salmasio and Rezzonici. This, despite the fact that my book is mentioned on all my gnonomic web sites, (freely downloadable as of a few days ago) and on my CD-Rom "Opera Omnia" of which to my great surprise there is no trace to be found in either the article nor the bibliograpby of Maes.

Re: The sundial of Emperor Augustus - english translation
Dear Frans and All, thanks for you answer. I know that the language is a great problem for the full knowledgment of our arguments. Like you, I have great difficulty to read long paper written in english or other language. I am sorry also for this message I am writing in my bad english... In relation to Augustus sundial, I believe a foundamental point: at today and in order at all historical and archaeological informations we have about the Augustus Sundial, we are not able (or we cannot to do) to be sure on the real design of this sundial. Kircher and more other ancient authors written it is a great and complete sundials. Buchner have found only a meridian line, but with more references on calendarial things. Today is impossible a mmaninary vision of a complete sundial with this enourmus dimensions, but a time of Augustus Rome have a more space structure and a great sundial like this can be possible. A question more important is the ubication of meridian line with the equinoctial line directed to Ara Pacis. It is not a case the posizion of Ara Pacis and i not believe Augustus building onlu a meridian line for his megalomania dreams. But I was very surprised to see missing my book, in which I written the history of this subject, the relations about calculations of high of obelisk, the position, the analysis of words from several manuscripts (who is Facundi Novus?), probably him not exist But, I am sorry because I have see that most more italian gnomonica pubblications is not in consideration from the gnomonic world people which not read the italian. Also my friend and phisician Edmondo Marianeschi have published many time ago a important article about this subject in the memories of Italian Gnomonic meeting, but also this work is missing in your bibliography. Patience...hope the gnomonic will be able, a day, to meet toghether all people and all language... The best wishes Nicola Severino - Original Message - From: "Frans W.
