Revisiting the compositional data. Some fundamental questions and new prospects in Archaeometry and Archaeology

In this paper we examine the problem of compositional data from a different starting point. Chemical compositional data, as used in provenance studies on archaeological materials, will be approached from the measurement theory. The results will show, in a very intuitive way that chemical data can only be treated by using the approach developed for compositional data. It will be shown that compositional data analysis is a particular case in projective geometry, when the projective coordinates are in the positive orthant, and they have the properties of logarithmic interval metrics. Moreover, it will be shown that this approach can be extended to a very large number of applications, including shape analysis. This will be exemplified with a case study in architecture of Early Christian churches dated back to the 5th-7th centuries AD

Mozarabic Chant anechoic recordings for auralization purposes

The Hispanic Rite is the liturgy celebrated by Christians of the Iberian Peninsula before the imposition of the Roman Rite in the mid-eleventh century. As in other early Christian liturgies, music was the core of the Hispanic Rite. This music, known as Mozarabic Chant is one of the richest musical repertoires of the Middle Ages. Currently, a research project is underway involving the restoration of the Hispanic Rite sound, using techniques of acoustic virtual reality. The project aims to perform the auralization of the sound of Mozarabic Chant in his primitive environment, that is, taking into account the acoustic characteristics of the pre-Romanesque churches in their original state. For this purpose, anechoic recordings were made for a number of musical pieces representative of the Mozarabic Chant repertoire. In total eight (8) musical pieces have been recorded and interpreted, each of one, by six (6) different singers. The recordings were made using a spherical array composed by 32 microphones. This paper describes the more relevant aspects related to the recorded musical material, the technical specifications and installation details of the recording equipment, the data processing, and a summary of the results.

II. Academic notebook, [ca. 1745]

This paper notebook contains undated and unattributed handwritten summaries and notes from published texts on world history, religion, and natural history, and was presumably kept by William Sever. The first page notes the death of poet Alexander Pope in 1744, constituting the latest date referenced in the notebook. The entries are typically short and offer condensed information on subjects including the histories of England, Japan and Siam; early Christian history; and natural religion.
