The contents of the fall in three categories: the opening section is the first detailed precis of the Hospitallers’ history; then comes the bulk of the treatise, presenting a concise summary of the Order’s constitution, institutional and legal organization, election procedures, recruitment of knights, rituals of instalment, and financial matters. The remaining section is a polemical expose arguing for the benefit of the Order’s abandoning of Malta and the recapturing of Tripoli. The offers a hitherto unexplored, first-rate source on the Maltese knights’ self-projection as a unique transnational institution of early modern Europe in the era of nation-states, on the power plays of the major political agents in the sixteenth-century Mediterranean, and on Western Christian strategies of engagement of Ottoman imperialism at the peak of its expansion in the region. Those interested in the history of Christian-Muslim interaction, the evolution of crusading practices in the era of early modern predatory warfare, and the construction of historical memory on the case study of the longest-lasting, and still extant, knightly order, will find it to be a highly intriguing and informative reading.
