There are so many things to be thankful for and so many people to give gratitude to that I will not forget them, but only mention a few. First and foremost, I am grateful to my mentor and supervisor, Associate Professor Benjamin Smith who has had an immense impact on my academic evolution, for guidance on previous drafts and for the insightful discussions that helped direct this study. Smith's previous intellectual contribution has been one of the corner stones around which this thesis was built. I extend deep gratitude to Professor David Lewis-Williams for his constant encouragement, the many discussions and comments on parts of this study. His invaluable contribution helped ideas to ferment. I am greatly indebted to Collin M. Turnbull for his insightful anthropological studies that inspired the many ideas in this thesis. In a special way, I thank my brother, Jimmy Kutosi for his invaluable support that enabled fieldwork in Uganda. Special thanks go to Susan Ward, the British Institute for East Africa, The University of Witwatersrand and the Rock Art Research Institute for the generous financial support to this study. Special thanks also go to Professor Merrick Posnansky for encouraging me along the way, and to Dr. Andrew Reid for all the support-mwebale nnyo ba ssebbo! To Dr. Geoff Blundell for inspiring me! In Kisumu, Kenya, a huge asante saana to Jack Obonyo of the Abasuba Community Museum, Dr. Mzalendo Kibunjia of National Museums of Kenya and Amolo Ng'weno of the Trust for African Rock Art, for assistance to Mfangano Islands. I recognise the contribution of the Uganda National Research Council for the permits and Dr. Ephraim Kamuhangire of the Uganda Museum for introductory letters that facilitated fieldwork in Uganda. To my research assistants: Micheal Robert Okwi, Dismas Ongwen and Alex Tamale, thank you very much for working tirelessly to ensure my fieldwork was successful.
