Volume Five of this Catalogue includes the Byzantine coins of the Palaeologan period (1258-1453) in the Harvard University collections. There is a slight overlap with Mi­chael Hendy's Volume Four for the three years 1258-61, since while on the one hand Michael VIII's coinage of Magnesia in these years is most naturally classed with that of his Lascarid predecessors, it is also desirable to have all his coins brought together for convenience of reference in a single volume.
