Dear friends,

Dear friends,
It is with great joy that I communicate the opening of the exhibit "FACCE, i molti volti della storia umana" (FACES. The Many Visages of Human History). The press conference took place on Feb. 13th in Padua and the doors were opened to the general public in February 14th, 2015.

I was honored to participate in the modeling of 27 facial reconstructions, which I will show below. An interesting fact to report is that all processes, from scanning of fossils and skulls to modeling and presentation of media (images, videos and augmented reality) were performed using only free and open source software.

The story the exhibition however begins in 2012 when the idea to reconstruct the face of a small hominid dead at the young age came to thought. It was the Taung child, an Australopithecus africanus with 2.5 million years. Back then, a partnership was established between the Museum of Anthropology at the University of Padua, the association of Italian anthropologists Antrocom Onlusand the Arc-Team research group in Italy, which I am part of.

The Taung Project was successful and I decided to extend the library of hominids reconstructed. I contacted the archaeologist Moacir Elias Santos, PhD and received hundreds of photographs of fossil replicas, which were 3D scanned and allowed for more than a dozen faces to be reconstructed. The result of this work was the exhibition "Faces of Evolution", organized by the Rosicrucian Egyptian Museum at the city of Curitiba, Brazil and inaugurated on May 18, 2013.

The idea the exhibition FACCE began to take shape still in 2013. It took months of discussions about the technologies and formats to be employed. Unlike the Brazilian exhibition, the Italian exhibition contemplates other fields, like a reflection on racism, the philosophical idea of what a face is, the masks covering one face with another one, the increase of species on the list of hominids and also the reconstruction of historic figures of Padua, which I had no idea of their identity at the time, and by the way, the last one was disclosed to me few months ago in late 2014.

To boost the interest of the general public on the exhibition we decided to present the face of the first paduan personality, the Portuguese Fernando Martins de Bulhões, who was to become a Franciscan and die as St. Anthony of Padua.

St. Anthony's face had a such broad impact we even lost track of the materials published on this work. That is from February to June 2014 when we finally presented his bust  in Padua.

The organization of the exhibition was made by Dr. Nicola Carrara (far left) and Dr. Telmo Pievani (second from right Dr. Carrara)
The FACCE exhibition that it is now inaugurated was the result of a partnership between the Museum of Anthropology at the University of Padua, the Antrocom Onlus, the International Museum of the Mask "Amleto e Donato Sartori" and the group of archaeological research Arc-Team.

For this event I was entrusted to reconstruct 27 faces, 22 of them related to human evolution:


  • Sahelanthropus tchadensis
  • Ardipithecus ramidus
  • Kenyanthropus platyops
  • Australopithecus afarensis
  • Australopithecus africanus (Mrs. Pless and Taung child)
  • Australopithecus robustus (Paranthropus robustus)
  • Paranthropus boisei
  • Australopithecus sediba
  • Homo habilis
  • Homo ergaster (Turkana boy)
  • Homo erectus (H. pekinensis)
  • Homo neanderthalensis
  • Homo rhodesiensis (H. heidelbergensis)
  • Homo heidelbergensis (Bodo)
  • Homo floresiensis
  • Homo sapiens (Cro-Magnon)
  • Homo sapiens (Idautu)
  • Homo georgicus 1 (classic cast, Zvedza)
  • Homo georgicus 2 (old)
  • Homo georgicus 3 (Mzia)
  • Homo georgicus 5 (2005)
And other 5 somehow related in one way or another with the city of Padua:


  • Egyptian priest of the Roman period (the mummy with sarcophagus are part of the museum's collection)
  • St. Anthony of Padua
  • Luca Belludi (Beatified friend of St. Anthony)
  • Francesco Petrarca aka Petrarch (considered the father of humanism, creator of the sonnet, was the one who coined the term "dark ages" to the Middle Ages)
  • Giovanni Battista Morgagni (considered the father of Pathological Anatomy, he was a professor at the University of Padua for 56 years)

Soon I will create other posts with more information and pictures about the personalities and the technologies involved with the exhibition.

I am very pleased and honored with this event. It is indescribable the joy of seeing one's own works composing such a scenario. In addition to feeling extremely cheerful, I also see myself full of gratitude to a number of people and institutions that made it all possible. I leave here my thanks to all of them:

Luca Bezzi, Alessandro Bezzi, Dr. Nicola Carrara, Emma Varotto, Moreno Tiziani, Dr. Takeshi Nishimura (KUPRI), Dr. Jorge Vicente Lopes da Silva, Paulo Henrique Junqueira Amorim, Thiago Franco de Moraes, Dr. Moacir Elias Santos, Vivian Tedardi, Liliane Cristina Coelho, Dr. Paulo Eduardo Miamoto Dias, Dr. Rodolfo Francisco Haltenhoff Melani, Msc. Aleksandro Montanha, Daniel Douglas Ludwig, Teófilo Fábio Macedo, Mari Bueno, Luciano Aguiar Vendrame, Lis Caroline de Quadros Moura, Vanilsa Inez Pagliari, Elizangela Patrícia Pagliari e Elias Francisco Pagliari.

Antrocom NPO patronises the exhibit "FACES. The Many Visages of Human History"



Antrocom nonprofit organization patronises the exhibit FACES. The Many Visages of Human History, which is held in the exhibition halls of the University Centre for Museums in Padua from February 14 to June 14, 2015.

The exhibition is the natural continuation of the Taung Project that, among other activities, also produced the reconstruction of the face of Saint Anthony, which has had great resonance among national and international media.

The faces tell our identity and our history: a personal story, but also the evolutionary history of our species. The face is anatomy, physics, physiology; but it is also a symbol, culture and interpretation.

The aim of the exhibition is to tell the various meanings that a face has and can acquire, thanks to finds and three-dimensional reconstructions of great visual impact. The scientific direction and supervision of the exposure are committed to Telmo Pievani and Nicola Carrara, while the three-dimensional and technological fulfilments are entrusted to Arc-Team and Cicero Moraes.

It is indeed a very special event that does not stop at mere display of artifacts, but it is a moment of reflection on forensic techniques used for the reconstruction of the face and on their scientific methodology. A moment that takes advantage of the most modern information technologies of modelling and sculptural development, with tests based on tomographies and original casts.

The exhibition seeks to reflect on the problems of management, usability and preservation of artifacts, especially if they are very fragile as the finds of biological origin.

Another peculiarity of the exhibition "FACES" is the will of the organizers to spread the potentialities offered by the open source world: not only using softwares with this kind of license, but by sharing the obtained three-dimensional models in an open and transparent way, with the opportunity to improve the realized work by other researchers scattered in different countries.

The exhibition is organized into five main themes:

1 - Let's face the human diversity: our origins through the casts of the main hominin fossils and their facial reconstructions, recreated with special forensic softwares and presented through augmented reality technologies. The exhibit also will present newly discovered species (Ardipithecus, Australopithecus sediba, Homo floresiensis) and, for the first time ever, the facial reconstructions of early hominins came out of Africa about 1.8 million years ago, discovered in Dmanisi site in Georgia (Homo georgicus).
The list of hominins on display:
  • Sahelanthropus
  • Ardipithecus ramidus
  • Kenyanthropus platyops
  • Australopithecus afarensis
  • Australopithecus africanus (Mrs. Pless and Taung child)
  • Australopithecus robustus (Paranthropus robustus)
  • Paranthropus boisei
  • Australopithecus sediba
  • Homo habilis
  • Homo ergaster (Turkana boy)
  • Homo erectus (H. pekinensis)
  • Homo neanderthalensis
  • Homo rhodesiensis (H. heidelbergensis)
  • Homo heidelbergensis (Bodo)
  • Homo floresiensis
  • Homo sapiens (Cro-Magnon)
  • Homo sapiens (Idautu)
  • Homo georgicus 1 (classic cast, Zvedza)
  • Homo georgicus 2 (old)
  • Homo georgicus 3 (Mzia)
  • Homo georgicus 5 (2005)

2 - One face, one race? Not really: the concept of "human race" is scientifically inconsistent. For example, the difference in DNA between an African pygmy and a European is only slightly higher than that the one we can observe between two pygmies or between two Europeans: we are all relatives and all different. Humanity is one!

3 - Faces from the past: five faces emerge from time. Five faces linked to, in different ways, the city of Padua. The oldest one belongs to an Egyptian priest of the Ptolemaic Period, whose mummy is preserved at the Museum of Anthropology. After the anticipation of June 10, 2014, the exhibit will propose again the reconstruction of the face of St. Anthony, along with the one of  Blessed Luca Belludi. The exhibition will give to the face of Francesco Petrarca, reconstructed for the first time, a voice to read the sonnet that opens the Canzoniere. The face of Giambattista Morgagni introduces the figure of another illustrious Paduan citizen, considered the father of contemporary pathological anatomy.

4 - The face as a mirror: famous people have dealt with physiognomy and phrenology: for a long time - as many popular sayings declare - it was considered that the moral qualities of a person were reflected in the external appearance, particularly in the visage. Removing the tinsels of old theories, the scientific study of the faces is continued over time because, undeniably, the face says a lot about us and our history, from both a personal and species point of view.

5 - From the face to the mask: the symbolic visage: covering the face is a gesture that distinguishes us from other animals. This is not a refined technique of mimicry because, although masked, we interact with others: the masks are rather fascinating symbolic territories. The masks on display are the most significant of the Museum of Anthropology, coming from different ethnographic collections around the world. Further, the contribution from the precious collaboration with the "Amleto and Donato Sartori" International Museum of the Mask at Abano Terme (Padua) enriches the section.

Facce: a digital poster for the exhibition

The opening of the exhibition "Facce. I molti volti della storia umana" will soon take place in Padua (14th February 2015), so I started to work also on dissemination tools, trying to focus on new media potentialities.
While the real communication experts will take care of the traditional promotion (posters, handbills, etc...), I would like to use the opportunity to test different methods.
Basically I am just developing a digital poster, which should be an reminder of the exhibition (with some essential informations) and, at the same time, an interactive showcase for the photos that the people sent us (and will send us) for our crowdsourcing campaign regarding the pareidolia phenomenon.
I think that the best way to realize this idea is to compile an app for Android, so that it will be accessible to many different smartphones. I designed the app to contain a WebViewer, linked to an address in our server, in which I uploaded an interactive gallery of images.
My first step has been a fast search in internet to find all the tools I was needing to develop my app, of course checking the licenses and choosing the open source software (an the simplest ones, being a newcomer in such field).
As first I focused on the gallery and I chose an MIT licensed  jQuery tool (jssor), with which I build this slideshow:


Than I looked for a software to develop my app and (thanks to +Michele Mazzurana) I came across another MIT licensed software, MIT App Inventor. This software has two main advances: it is based a GUI (very simple) and it does not require an emulator to test the work (if you have an Android device, you can directly connect it with your project).
Here is a screenshot of the direct link between the software and the mobile:

If you want to test the app, you can download it here. Please notice that to visualize the gallery you will need an internet connection, so (depending on your contract) your provider could put additional costs (no problem if you have a flat rate or if you use free wifi access).
I hope this post was useful, have a nice day!

PS
If you have pictures regarding the pareidolia effect, you can upload them on the FaceBook page of the exhibiotn "Facce" (do not forget to write the author, the title and the license, for the credits). Day by day the pictures will be uploaded in the gallery of the app.

3D printing for Cultural Heritage

As many of you know,
since last year we are working on the preparation of the open source exhibition "FACCE. I molti volti della storia umana" (here some news in ATOR: 1, 2 and here the official page and the FB page). Of course all the software we are using are Free and Open (FLOSS), but for some particular exhibits, we are working also with open hardware.
Our interest in this specific topic dates back to 2006, when we started investigating the potentialities of open hardware in archeology, especially in the field of aerial photography e rapid prototyping. We get the first results in 2008, with our UAVP prototype (here some news from ATOR: 1, 2) an all the other UAV we built (KK, etc...).
For the exhibition the main open hardware we used are 3D printing machines. We experienced different solutions: +Leonardo Zampi printed the 3D model of the Taung Child thanks to the Kentstrapper machines, an ideal choice if you want an hardware which is ready to work out of the box (here the related articles: 1, 2)...


The Taung Child printed in the Volta printer (Kentstrapper)

... and we build our own device from the scratch, a Fa)(a 3D, thanks to +Giacomo Falaschi  and +silvio tassinari , of Roma Makers.


Building the Fa)(a 3D at Roma Makers lab.

One of the main issue in 3D printing for Cultural Heritage is to replicate an object in the right scale (otherwise you will just print a souvenir) and this is why it is very important to know how to perform a 3D scan, but also how to post-process your data ( (in ATOR you will find a lot of informations about this), in order to send the right file to the machine.
Here are some example of the models we are printing for the exhibition (scale 1:1): some 3D skulls of hominids (different individuals of Homo georgicus) we were able to scan, tanks to the kindness of Prof. David Lordkipanidze, during our mission to Tiblisi and Dmanisi. We will use them to prepare some Augmented Reality interactive exhibits related to paleoart.
