The Theological Tractates and The Consolation of Philosophy, by Boethius. Facing page translation of a classic period Latin text, including a near-period English translation of the latter book.
A General History and Collection of Voyages and Travels, v.VIII. More late-period travelogues.
Shakespeare: His Life, Art and Characters, With An Historical Sketch of the Origin and Growth of the Drama in England, v.I.
English Travellers of the Renaissance (1914).
Zarlah, The Martian (1909). Sounds incredibly cliched at a quick glance, until I consider its age -- this is clearly from the genre that bad 1940's sci-fi movies drew from.
Beaumont and Fletcher's Works, v.2: Wit Without Money. (A Comedy)
Authorised Guide to the Tower of London (1909). Basically a walking-tour guide to the Tower and everything in it. Lots of illustrations.
A History of Pantomime (1901). Potentially of interest to the Commedia crowd, since it appears to spend a lot of time talking about the evolution of the prototypical clown, and specifically Harlequin.
Experiments with Alternate Currents of High Potential and High Frequency, by Nikola Tesla. A summation of a lot of the work he is famous for, it appears, with pictures of cool gadgets.
The Story of Sigurd the Volsung, by William Morris et al. I'm sure gyzki could opine about the worth of this modern telling of ancient saga.
An Essay on Mediaeval Economic Teaching (1920).
