1. Reconstructing Ancient Technology: The analysis of Pre- Columbian Ecuadorian Textiles

2. Project Objective To uncover aspects of the Guangala culture through analysis of textile impressions on pottery sherds.

3. Introduction The people of the Guangala region lived between 500 BC and AD 800 –Southwest Coastal Ecuador –No recorded history –Left artifacts with textile imprints

4. Background Information: Culture Textiles played central role in pre- colonial South American cultures. Textiles often showed status, identity, and had ceremonial implications. Mummy from Paracas, Peru

5. The Guangala (500 BC – AD 800) No evidence of any social stratification. Communities simply organized. Evidence that they were long-distance traders. Not definitively tied to any modern culture.

6. Textiles and Ceramics in the Guangala The Guangala also used textiles in ceramics. Textiles were usually recycled textiles, not textiles made specifically for ceramic production.

7. Background Information: Textiles Important component of Textiles: Warp and Weft

8. Types of Plain Simple Weaves Balanced Weft-faced Warp-faced

9. Textile Characteristics to Find Number of threads in the warp and the weft Type of weave The fiber type Thread diameter Number of threads per centimeter Regularity

10. Method Artifacts vs. experimental molds Negative to positive images

11. Observation Techniques Photography Light microscope SEM

12. Experimental These are modern textiles of known material and technological processes. Compared to artifacts.

13. Cotton Saddlebag

14. Cotton Towel

15. Sheep Wool Bag

16. Cabuya Coaster

17. Cabuya Purse

18. Alpaca Poncho

19. The Artifacts Artifacts range from Early Guangala (Artifact 5) to Late Guangala (Artifacts 1 and 3). From El Azúcar Valley – varied sites.

20. Artifact 1

21. Artifact 1 - Cast Excavated Floor

22. Artifact 2

23. Artifact 3

24. Artifact 3 - Cast

25. Artifact 4

26. Artifact 4- Impression

27. Artifact 4 - Cast Above: Weft dominant Below: Warp dominant Above: Artifact cast Below: Alpaca poncho

28. Artifact 5- Artifact, Casts

29. Artifact 5 Side A Simple Plain Balanced Superimposed

30. Conclusion Hypothesis: Balanced Plain Weaves, irregularities, worn-down textiles Actual: complex weaves with evidence of designs and color schemes Conclusion: Sophisticated and Skilled Alpaca fibers found although evidence suggests that there were no llamas on the coast Trading System and Economic System
