AN ABSTRACT OF THE THESIS OF Sally Jo Ishikawa for the degree of Master of Arts in Interdisciplinary Studies in the co-departments of Apparel, Interiors, and Merchandising, Museum Studies, and Anthropology, presented on May 5, 1989. Title: A Methodology for Analysis of Historic Textiles: Ancon, Peru Redacted for privacy Abstract approved: r Dr. LoErna Simpson Twenty-four woven Pre-Columbian textiles in the Apparel, Interiors and Merchandising Department (AIM)of Oregon State University were reported to be from Ancon, Peru. A methodology was developed to confirmthe exact provenance of the AIM textiles. Technical fabrication characteristics were utilized to describe certain known Ancon woven textiles and to analyze the twenty-fourAIM textiles; then comparisons were attempted between thetwo groups to determine if internal patternsfor each were identical. A literature and collection survey identified ten documented reports of known Ancon woven textiles. The previously recorded information of the known Ancon pieces was summarized. Technical fabrication characteristics for each AIM textile were observed and recorded. The technical fabrication characteristics included weave structure, thread count, fiber content, direction ofspin, ply, degree of twist, yarn diameter, color andmotif. Frequencies and especially developed analysis tools were utilized to identify internal patterns. Hypothesis 1 stated that information about the technical fabrication elements of Ancon woven textilesin certain other collections can be organized intointegrated patterns. Hypothesis 1 was not supported because data recorded on Ancon woven textiles was incomplete,and therefore only able to give limited frequencies. Hypothesis 2 was supported: The twenty-four woven Pre-Columbian textiles from the Costume and Textile Collection of the Apparel, Interiors andMerchandising Department of Oregon State University will havesimilar patterns in technical fabrication elements. An analysis tool was developed to show patterns withintechnical fabrication elements. Thread count, direction of spin, ply, and degree of twist exhibited internalpatterns. Hypothesis 3 stated that the provenance of twenty-four woven Pre-Columbian textiles, from the Costume and Textile Collection of the Apparel, Interiors and Merchandising Department of Oregon State University is Ancon, Peru. This hypothesis could not be tested because technical fabrication patterns for the known Ancon weavings were not complete and could not be statistically analyzed. Even though the two sets of data populations (data from known Ancon textiles and data from the AIM collection) could not be compared statistically, some information was gained by a review and comparison of simple frequencies of internal patterns. Thread count frequencies for both populations exhibited internal patterns.

Deepest appreciation to Dr. LoErna Simpson, Apparel, Interiors and Merchandising, for her wisdom and guidance. Dr. Richard Ross, Department of Anthropology, was the impetus for the hypotheses; Lucy Skjelstad, Museum Studies, was extremely enthusiastic and supportive; and Dr. William Jenne' was a thoughtful editor. A sincere thanks and appreciation go to the many other people who were instrumental to this research document: Mike Kellogg measured yarns using the Hewlett-Packard OGP Tony and Paula Yokoyama - took photographs of yarns using a photomicroscope Karen Hennessy - translated a crucial passage in a Peruvian dye manual Jeannine Horton - my friend and weaving mentor Finally, deepest gratitude is expressed to my friends and family for their encouragement and understanding. Their constant faith and support were imperative. My husband and best friend, Les, was tireless in his encouragement and understanding. Thank you for setting up the computer, and helping to format the print. Thank you for eating soup night after night. Thank you for being forgiving when I was tired. Thank you. Thank you.
