The following pages present the results of an expedition organised in the autumn of 1893 for the purpose of investigating the antiquities of the Boman town of Doclea, in Montenegro, the reputed birthplace of Diocletian. Excavations had already been carried on there during three seasons by H.H. the Prince of Montenegro, to whom the explorers desire to record their grateful acknowledgments, not only for his gracious permission to continue the work so auspiciously begun, but also for the kind reception and many facilities accorded to them. To M. Paul Rovinski also, the skilful director of the former excavations, they owe the warmest thanks. His generous co-operation and his local experience were simply invaluable, and his genial friendship can never be forgotten.
