La centuriazione romana (pubblicazioni di AC Sparavigna)
La Limitatio Romana: Alcune Definizioni (2020) - Sparavigna, Amelia Carolina - Prima parte di una discussione sulla tecnica di agrimensura romana, detta limitatio o anche centuriazione. Si forniscono alcune definizioni. L'uso della groma, uno degli strumenti usati dagli agrimensori, sarà analizzato in dettaglio La discussione ha lo scopo di preparare ad una ulteriore discussione sull'orientamento della limitatio.
Si propone un sunto di alcune definizioni relative alla tecnica degli agrimensori romani. Compreso l'uso della groma.

Sparavigna, Amelia Carolina, Roman Centuriation in Satellite Images (December 26, 2015). PHILICA Article number 547, Available at SSRN: https://ssrn.com/abstract=2742223 Abstract: The satellite images of Google Earth can show us how the Roman divided the land in their colonies, according to the surveying system of Centuriation.

What the Latin literature truly tells us about the orientation of camps, towns and centuriation (2020). Sparavigna, Amelia Carolina - "Here we are proposing a presentation and translation of some parts of the work by J. Le Gall on the solar orientation of the Roman camps, towns and centuriation. Le Gall is giving us a detailed description of the Latin literature regarding this orientation. The article, that was published in 1975 in the Mélanges de l'école française de Rome is therefore a fundamental reading so as not to get biased by any suggestion about solar orientation, that we can find in modern literature."
Il fondamentale articolo in Francese di Le Gall è disponibile liberamente in rete.

Storia della Scienza nel Mondo Antico (pubblicazioni di AC Sparavigna)
A.C. Sparavigna (2011) Water, air and fire at work in Hero's machines. In: ARCHAEOGATE n. 24-01-2011. - ISSN 1973-2953 - anche reperibile in https://arxiv.org/abs/1101.3470 Abstract: Known as the Michanikos, Hero of Alexandria is considered the inventor of the world's first steam engine and of many other sophisticated devices. Here we discuss three of them as described in his book "Pneumatica". These machines, working with water, air and fire, are clear examples of the deep knowledge of fluid dynamics reached by the Hellenistic scientists.

A.C. Sparavigna (2011). Ancient concrete works. arXiv:1110.5230 Abstract: It is commonly believed that the ancient Romans were the first to create and use concrete. This is not true, as we can easily learn from the Latin literature itself. For sure, Romans were able to prepare high-quality hydraulic cements, comparable with the modern Portland cements. In this paper, we will see that the use of concrete is quite older, ranging back to the Homeric times. For instance, it was used for the floors of some courts and galleries of the Mycenaean palace at Tiryns.
Già il palazzo miceneo di Tirinto aveva i pavimenti in cemento. Come era fatto questo cemento? ... E' una storia interessante quella relativa alla scoperta di questo cemento, Leggendo il mio testo potete trovare che c'è di mezzo Schliemann e alla sua ricerca di tesori nascosti. Nel 1876, Heinrich Schliemann, considerando il palazzo di Tirinto come poco rilevante per lui - lo riteneva medievale - si mise d'impegno, e quasi lo distrusse, cercando di andare sempre più in basso alla ricerca di tesori, e così bucava i pavimenti di cemento.

A.C. Sparavigna (2014) Some Notes on Ancient Concrete, International Journal of Sciences 02(2014):1-6 DOI: 10.18483/ijSci.412 Abstract: Concrete is a material composed of coarse granular particles embedded in a binder that glues the particles together. It is commonly believed that the ancient Romans were the first to create and use such material, but this is not true, as we can easily learn from the Latin literature itself. Without any doubt, Romans were able to prepare high-quality hydraulic cement, comparable with the modern Portland cement. In this paper we present some notes on the ancient concrete. From Rome, we will go back in time, showing how the Greeks used it in their Mycenaean royal palaces. The paper continues talking about an Egyptian concrete and ends discussing the use of concrete during Neolithic times.
Il cemento non è invenzione moderna e neppure dei Romani. I Romani hanno inventato il cemento idraulico.

A.C. Sparavigna (2011), Materials Science in Ancient Rome, ARCHAEOGATE, July 23, 2011. Abstract: Two books, the "De Architectura" by Vitruvius and the "Naturalis Historia" by Pliny the Elder, give us a portrait of the Materials Science, that is, the knowledge of materials, in Rome at the beginning of the Empire. Here, I am reporting some very attractive contents that we can find in these books. The reader will see the discussion proposed in fours case studies: concretes, coatings, amorphous materials and colloidal crystals, to describe them in modern words.

A.C. Sparavigna (2012) Faience: the ceramic technology of ancient Egypt. In: ARCHAEOGATE n. 12-Febbraio-2012. - ISSN 1973-2953 Abstract: The term “faience” is commonly referred to a glazed earthenware, the use of which spread in Europe during the Renaissance from France and Italy. The term was derived from Faenza, the town in Italy, where the glazed earthenware was mainly produced. The other name often used for this earthenware is “majolica”. Majolica itself had a long tradition in the North African and Near East Islamic production of ceramic. In the 19th century, European archaeologists used the misleading name of “Egyptian faience” to designate the siliceous ceramics produced in the ancient Egypt. The ancient faience was a completely different material created to imitate the gloss and colour of gems and precious stones. This material started to be used in jewellery in Egypt and the Near East, about the fourth millennium BC, that is, during the predynastic age."
A.C. Sparavigna (2014). Ancient Technologies: The Egyptian Sintered-Quartz Ceramics. PHILICA Article number 426. 14 Settembre Mar 2014 - Available at SSRN: https://ssrn.com/abstract=2742291 Abstract: To physicists and engineers, ceramics represent materials demonstrating excellent strength and hardness, materials that can serve as electrical insulators or conductors, some of them being able of a high-temperature superconductivity. To researchers working in archaeology and art history, ceramics mean objects such as figurines, tiles and tableware helping understanding cultures and technologies of the past. They are among the most common artifacts to be found in archaeological sites, because made of an imperishable material. Then, ceramics are for interdisciplinary studies the subjects by excellence. Here we will discuss the Egyptian faience, a ceramic based on sintered-quartz materials, an old high-tech material that allows creating objects which have glossy surfaces with lustre of various blue-green colours. This paper shows how faience had been produced and discusses some methods used for its analysis.

Penso che il riferimento sia al fatto che non si leggono più le opere antiche in Latino o in Greco.

Il mito di Roma
Non solo una città, ma nucleo generatore di miti, luogo che fin dall'antichità ha offerto metafore e modelli alle lotte politiche, ai conflitti religiosi, alle scelte culturali. Dal Medioevo a oggi, Giardina e Vauchez raccontano la presenza del mito di Roma all'origine delle idee politiche che ancora animano l'attualità. La concezione universalistica dell'impero medievale e del papato, la difesa delle libertà cittadine e dei valori dell'autogoverno, l'immagine trionfante della Rivoluzione francese e la vocazione scenografica del fascismo sono le principali tributarie del mito di Roma, così come lo sono stati tutti quei movimenti che, dalla Riforma protestante ai nazionalismi ottocenteschi e al nazismo, si sono riconosciuti in un'identità 'antiromana'. Fra riabilitazioni e cadute, fra entusiastiche adesioni e drastici rifiuti, il mito di Roma continua a vivere un destino alterno, nelle cui pieghe corre la strada maestra della nostra storia
