5/5 ❤️ The result? We can start to identify real and meaningful differences in how different ancient communities crafted vessels with unique shapes and recipes 🏺

Stats is not just for spreadsheets, it can also tell us stories of human creativity! #Archaeology #DataScience #StatisticsInAction

4/5 📈 #MANOVA tests (to test whether identified ware clusters really mean something)

3/5 🎨 #PCA plots (to reduce the many variables we take under consideration and look for trends across pottery styles, dates, and #archaeological sites)

2/5 🌀 #EllipticalFourierAnalysis (to translate the curves that make up pottery shapes into equations!)

Thank you very much for the invitation and the hard work to the organisers from the Otto-Friedrich-University Bamberg, the German Mining Museum in Bochum, and the Museo Nacional de Costa Rica.

Jasmine discussed the #computationalmodelling of #Muisca goldwork; and Marcos introduced the overarching goals and recent results of the #REVERSEACTION project.

Lina talked about her work on #Malibú #goldwork and its role in local #ontologies in the Colombian Caribbean. In the words of Lina, it was "astonishing to see the similarities of the Costa Rican collections with the northern Colombian metalwork" 3/

The workshop connected researchers working on the topic in the #IntermediateArea and #Mexico, revealing fascinating continuities and discontinuities in the use of metals by communities in the past, and sparking discussion on various approaches to their study and interpretation 2/ #archaeology

Estos bloques contienen pequeños fragmentos de copas de Nariño (provenientes de objetos ya rotos), y esperamos investigar la composición de la pasta de arcilla. (3/3)

🇨🇴 ¡Feliz Año Nuevo! ¡REVERSEACTION ya ha regresado a los laboratorios para preparar bloques pulidos para análisis con microscopía electrónica de barrido! (2/3)

6️⃣The new modelling tools are readily applicable beyond archaeometallurgy, e.g, to compositional studies on ceramics or glass, or even to modelling the variability of diets in isotopic studies

5️⃣The new tools were applied to the study of Muisca goldwork from pre-Hispanic Colombia (AD 600-1600). The findings suggest the intra-regional circulation of imported gold, with people pooling metals from a variety of geological sources for communal festivities.

4️⃣Hierarchical (multilevel) model specifications can simultaneously consider both local and regional patterns in past craft production activities, whilst also accounting for sampling uncertainty. Think of it as zooming in and out on the past!
