_ We possess a precious monument of the Penguin literature of the fifteenth century. It is a narrative of a journey to hell undertaken by the monk Marbodius, of the order of St. Benedict, who professed a fervent admiration for the poet Virgil. This narrative, written in fairly good Latin, has been published by M. du Clos des Limes. It is here translated for the first time. I believe that I am doing a service to my fellow-countrymen in making them acquainted with these pages, though doubtless they are far from forming a unique example of this class of mediaeval Latin literature. Among the fictions that may be compared with them we may mention "The Voyage of St. Brendan," "The Vision of Albericus," and "St. Patrick's Purgatory," imaginary descriptions, like Dante Alighieri's "Divine Comedy," of the supposed abode of the dead. The narrative of Marbodius is one of the latest works dealing with this theme, but it is not the least singular. _
