The tradition of classical studies in Poland goes back to the Middle Ages. The first historical chronicle, written in Latin, appeared in this country in the twelfth century. At present Latin is taught in about 30 per cent, of our grammar schools. The course covers four years of instruction, and the texts studied are those of Nepos, Caesar, Sallust, Livy, Lucretius, Cicero, Ovid, Virgil, and Horace. Greek is studied at the universities, mainly by students of classical philology, although its knowledge is also required in some other fields of the humanities.
