materials and establish a time line. The results of these were published in 1954 as La ceramica arqueológica de Cholula. The pieces ranged from clay figures made when the settlement was just a village, to the Pre-classic. The latter ones include figures that are definitely nude females with complicated hair styles. Figures from later periods, such as those coinciding with Tula and Teotihuacan, tend to be of gods and priests. Various musical instruments, such as flutes, were also found, as well as tools for the making of textiles, amate paper and axes. One major find included a ceremonial scepter carved from bone, with images related to the concept of life and death as a duality. The first round of excavation work ended in the 1950s. The second round of excavations took place from 1966 to 1974 under the name of Proyecto Cholula. This was spurred, in part, by reconstructed pyramids in Mexico, which had become tourist attractions. This project was sponsored by both the federal and state governments, who wanted to make Cholula an attraction, as well. The archaeology and anthropology fields had experienced changes since Marquina's work, mostly focusing on a more interdisciplinary approach. The first person in charge of the site was Miguel Messmacher in 1966. After only six months of work, Messmacher released a preliminary report in 1967. One of the main finds during this time was that of Edificio I (Building I). In addition to the excavating of the main structures of the pyramid, Messmacher, Eduardo Matos Moctezuma and others in the project worked on more multidisciplinary tasks, such as determining agricultural patterns of the site, ceramic development and water distribution systems. However, this put them in conflict with the sponsors of the project, along with the INAH, which favored a more restricted approach that focused on reconstructing the pyramid. In 1967, INAH decided to replace Messmacher with Ignacio Marquina as head of the team excavating the site, which prompted most of the younger researchers to leave the project. While the focus was placed back on the pyramid proper, the project did not lose all of its interdisciplinary character, keeping experts in areas such as geology, botany and paleozoology. The project began to focus on the south side of the pyramid, excavating the remains of plazas and buildings that made up a large complex. However, it was difficult to link these structures to those in the
