Dear friends, a new issue of the Italian magazine Orologi Solari is available for download from the usual site http://www.orologisolari.eu/.
Here is the list of articles together with a short abstract: 1. "Hour lines in ancient sundials are not straight on plan. A case to be studied." by Albéri Auber Paolo The only case of a supposed ancient flat sundial with non-rectilinear hour lines (a horizontal dial described by Fiorelli in 1865 and with n. 4007 in the Gibbs catalog) is examined and discussed in detail. Based on the course of the hour lines and the writings around them (also analyzed by epigraphic experts) it is concluded that the dial in question is almost certainly a modern fake. 2. "Preserve the human memory of Seminars" by Azzarita Francesco Beyond the official acts, it is considered interesting to preserve the memories of these meetings - and thus constitute the "human memory" - through faces, events, stories, cartoons and images. The author begins by presenting the Speakers and also the simple registered members to the 21 Seminars, the group photos, the cartoons and so on, hoping for a continuation in the future. 3. "Pasquale Monti manufacturer of sundials" by Coco Nicola The author presents an old text by Pasquale Monti about the search of the meridian line and the construction of a vertical sundial. He also shows his production in accordance with the instructions provided by the artist. 4. "The functional restoration of the Ferrara sundial" by the Editorial board Information and photos related to the restoration work carried out on the vertical sundial in the square of the town hall of Ferrara, performed by our colleague Renzo Righi for the gnomonic aspects, are reported. 5. "Roman inscripted stones and sundials - Revisions and updates (part 1)" by del Favero Enrico Some descriptions of inscripted stones from the Roman era, found near the Dolomites in the province of Belluno and in Pompei, and concerning sundials donated to local populations by benefactors of the time, are revised and updated. To these descriptions, which date back to about 20 years ago, others of new discovery and varied provenance have been added. However, all this could also benefit from a photographic color documentation completely absent in the past. 6. "Fake sundials" by Ferrari Gianni On the walls or in the gardens today we often observe artifacts that look like sundials, but which are not suitable for marking the hours, because they are poorly designed or incorrectly installed. The article discusses these objects, breaking them down into categories and presenting numerous examples. It also clarifies how some time indications can occasionally be drawn from these incorrect instruments. 7. "Remembering the gnomonist Giovanni Flora" by Flora Giuseppe, Francesco, Silvano and Lucia The gnomonist colleague and friend Giovanni Flora is remembered by his sons in these pages with photos of some of his many gnomonic achievements. 8. "Construction and use of a MODULE for a dialling scale" by Gunella Alessandro Taking inspiration from an idea advanced at the end of the sixteenth century by Clavio, the author proposes an elementary figure, which he called MODULO (a sort of "Dialling Scale", valid for only one latitude) and explains how to use it to build sundials on various inclined planes. 9. "Giovanni Battista Benedetti: “De gnomonum umbrarumque solarium usu”" by Gunella Alessandro The author presents the translation of Benedetti's text (1530–1590), included in the bonus of this magazine, and expresses his appreciation for the work both for its technical content and, as a good Piedmontese, for its publication in Turin in 1574. 10. ""Conversi ad Dominum" - Astronomical orientation of some historical places and churches of Cremona and Brescia" by Margotti Mario The author investigates the geographical orientation of ancient churches, confirming the hypothesis that this orientation was linked to very specific religious reasons and justifying the deviations from the classical East-West direction, present in several cases. A digital bonus can also be downloaded for additional reference material. Hope you will enjoy the reading, although in Italian only. Ciao. Gian Casalegno
