Edward Rand was a prolific scholar of Latin literature published several translations of Horace and Boethius, and also a number of works on the Classical tradition in Western culture and the relevance of the Classics in the modern era. In this essay he describes a key manuscript supporting the fragmentary texts of Ovid, Palladius, and Tacitus acquired by Harvard University. This manuscript still remains one of the few source documents for Tacitus, and author whose work was nearly lost to modernity, and this essay provides illuminating insight into the process by which such fragmentary sources become full texts of ancient literature.
