Matero Associate Professor of Architecture Graduate Program in Historic Preservation University of Pennsylvania ACKNOWLEDGEMENTS This thesis would not have been possible without the involvement and contribution of several people. First and foremost, I must thank my advisor, Frank Matero, for giving me the opportunity to pursue this topic and for lending his expertise on the subject. His guidance and patience throughout the entire process is sincerely appreciated. Many thanks to my reader, Beatriz del Cueto, and Gus Pantel for their extensive knowledge of the site and for the opportunity to take part in the current restoration. Their enthusiasm and dedication to Iglesia San José continues to motivate me. I would like to thank Edwin Colón Rios and the masons at the National Park Service, San Juan National Historic Site whose knowledge of lime mortars was invaluable and for preparing and donating materials of the highest quality. I extend my thanks to Dr. Tami Lasseter-Clare whose continual support and candid advice kept me focused on my research. A very special thanks to my classmates, Bhawna Dandona, Frances Ford, Christy Lombardo, Victoria Pingarron Alvarez, and Kelly Wong, who sacrificed their own research time to help me in the lab, and to Nahal Badiian-Farahani and Zahira Machido for their excellent translation skills. Finally, a heartfelt thank you to my family and friends, especially my parents, whose encouragement and support means so much to me. ii TABLE OF CONTENTS
