ABSTRACTOver 108 samples of mural paintings from Teotihuacán, México, were studied by scanning electron microscopy, optical microscopy and X-ray diffractometry. The results show a sequence in the techniques employed to produce the mural painting's supporting plasters -made of lime and different sands. The technical stages found can be used as archaeological data to help understand the continuous evolution of 800-year mural paintings. The consequences of our study are discussed in detail.

AbstractTwo hitherto unrelated Teotihuacan mural paintings, no longer in situ, probably are companion pieces from upper and lower walls in the same portico or room or in related porticos or rooms of the same compound. The tassel headdresses worn by the figures in the paintings appear to be insignia of "Rain God"-related social units or institutions, signifying leadership and authority, with military associations. The contexts in which the tassel headdresses occur, both within the ancient city and outside its borders, suggest that persons with rights to the headdress may have been members of or attached to the ruling establishment or the bureaucracy of the Teotihuacan state. The unique two-part notation on the upper wall painting appears to be hierarchically ordered, corresponding to a ranking either of the social units to which the figures belong, or of institutions which they represent, or of places associated with them.

AbstractIn February, 1963, an unusual discovery was made at La Ventilla, less than a mile from the “Ciudadela” in Teotihuacán, Mexico. This find is a composite or sectional stela made up of four superimposed elements that fit into each other by means of stems and orifices. All elements are different in form and are, from top to bottom, discoidal, globular, conical, and cylindrical, the last fitting into a platform base. This piece is unique in Mesoamerican archaeology and seems to have no significant parallels elsewhere. This stela was carved during the Classic period of Teotihuacán. Its function has been clarified through comparison with mural paintings of the Tlalocan in Tepantitla, Teotihuacán, where a ball-game scene is portrayed, and at each end is a stela that is almost identical with that of La Ventilla. It seems evident that the La Ventilla monument is a ball-court stela-marker.

AbstractIn this paper, a comparative study was conducted on the extraction effects of six agents for collagen-based mural painting binders. These agents were used to extract the residual proteins in the non-aged and thermal aged samples. The protein extraction efficiencies of different extracting agents were quantitatively determined by bicinchoninic acid (BCA) method, and then processed by multivariate analysis of variance (MANOVA). The impact of the extraction process on the protein structure was characterized by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), ultraviolet absorption spectrum (UV) and circular dichroism (CD). The results showed that, for both non-aged and aged samples, the extraction efficiency of 2 M guanidine hydrochloride (GuHCl) was significantly higher than the other five agents, with less damage to the protein structure during the extraction process.

The 1960S

Techinantitla building complex, in the Amanalco neighborhood of the ancient city of Teotihuacan, is famous for the iconography and quality of the mural paintings found in this site. A significant part of this heritage has been lost due to looting. In recent years, an interdisciplinary research project was developed to study the limited patrimony that was left. As part of this study, we first employed geophysical techniques to reconstruct the architectural pattern of the compound’s remaining walls, where other paintings may still be found. Then, we applied a non-invasive methodology to characterize a large set of fragments recovered in the 1980s and to gain information on their pigments and manufacturing techniques. This methodology included False Color Infrared Imaging, X-ray Fluorescence and Fiber-Optics Reflectance Spectroscopy, and led to the identification of hematite, calcite, malachite, azurite and an unidentified blue pigment. The results were compared with a previous study performed on a set of Techinantitla mural paintings looted in the 1960s. A broader comparison with contemporary mural paintings from other Teotihuacan complexes shows good agreement in the materials used. These results may suggest a standardization in the making of Teotihuacan mural painting during the Xolapan period (350 to 550 AD).

Within the framework of conservation and assistance for the restoration of cultural property, a method of analysis assistance has been developed to help in the restoration of cultural heritage. Several collaborations have already demonstrated the possibility of defects detection (delamination, salts) in murals paintings using stimulated infrared thermography. One of the difficulties encountered with infrared thermography applied to the analysis of works of art is the remanence of the pictorial layer. This difficulty can sometimes induce detection artifacts and false positives. A method of thermograms post-processing called PPT (pulse phase thermography) is described. The possibilities offered by the PPT in terms of reducing the optical effects associated with the pictorial layer are highlighted first with a simulation, and then through experiments. This approach can significantly improve the study of painted works of art such as wall paintings.

This paper presents the acoustic study of a sample of sonic artefacts, in particular a selection of wind instruments (horns, trumpets and pipes), from the UNESCO World Heritage Centre of Teotihuacan, Mexico, based on a thorough examination of the accessible and playable archaeological finds and the construction and subsequent test of a series of experimental models. Combined with the archaeological and iconographical information, the study helps to deduce information with regard to the urban settings in which these instruments might have been used. It also reveals some basic acoustic components of the music once performed in Teotihuacan.

AbstractAn effort is made to give readers a good idea of what the techniques of factor, cluster, and proximity analyses are; of what are their good features and their limitations; and where one should look for further information. Archaeological uses of these techniques which are discussed include those of Hodson on La Tene brooches and on Mousterian assemblages, L. and S. Binford on Mousterian assemblages, Freeman and Brown on the Carter Ranch Pueblo, and the author on data from Teotihuacan, Mexico. The dangers of using correlations based on inadequate samples are stressed, and one necessary (though not sufficient) condition for sample adequacy is suggested. It is argued that proximity analysis, among other applications, is probably better than the Brainerd-Robinson approach for seriation.
