This book is neither a history of Ethiopia nor a series of biographies of the rulers described – such has been more properly attended to by more qualified persons elsewhere. My role has been that of an antiquarian – a person who studies or collects old and valuable or rare objects. I have not directly accessed any primary sources, but I have had the good fortune, often online, to be able to refer to a wealth of published material – articles, collections, biographies, histories, studies, reports and websites from which I have been able to extract and collect the many references to the Order of the Seal of Solomon.
