Slightly OT: What is your oldest book?

I suspect that many of you collect books other than fine press books and are likely therefore to have something in your library/collection that might be somewhat aged. If you are willing to satisfy my curiosity, please let us know what is the oldest book in your library.

In my case, that would be Marcus Tullius Cicero, De officiis libri tres : Cato Major; vel, de Senectute. Laelius; vel de Amicitia. Paradoxa Stoicorum sex. Somnium Scipionis : cum optimis ac postremis exemplaribus accuratè collati, Amstelodami (that is, Amsterdam): ex officina Elzeviriana, 1656. This is a small book, a 16mo, bound in full limp vellum with wallet edges. I don't read Latin, but this is in my collection as an example of fine printing by the Elzevirs.

Next oldest: my set of David Hume's History of England (8 volumes), the first posthumous edition of 1778, in original period sprinkled calf and still in pretty decent shape.

What's in your collection?

My oldest is a first edition Eikon Basilike from 1649 (although marked 1648). Although it is not a fine binding.

Not mine, but my father has what appears to be the original, handwritten log book of the Greenwich Observatory from 1776. I had fun decoding that when I was a kid. I suspect these were recorded in triplicates?

Virgel Virgil, Virgilii Maronis Bucolica and Maronis Georgica. Paris: A. Wechel, 1555-6. Octavo, tree calf (rebacked). I don't read Latin but my partner does. When I was teaching, I used to bring sample books from my collection to show my students, who otherwise had little idea of printing history. They were impressed to see a book printed before Shakespeare was born! I have done my best to cultivate the next generation of book collectors!

My oldest book in English is Poems by the most deservedly Admired Mrs. Katherine Philips, The Matchless Orinda. London: J.M. for H. Herringman, 1667.

There's some pretty nifty stuff here. I like it! I had one from 1554 that was printed in a beautiful Greek italic font, but sold that one some years ago, so it doesn't count.

Keep it going, people!

Seneca's Morals a small octavo bound in full leather (but the spine and corners have been redone) with marbled edges (mostly faded) T.N. for Henry Brome at the Gun (1679) though the title page says 1671.

It's been rebound at some undetermined point in green leather (I chose a generic LT cover to represent it), so doesn't quite qualify, but the insides are 1661:

The Gentlemans Exercise or, An exquisite practise, as well for drawing all manner of Beasts in their true Portraiture: as also the making of all kinds of colours, to be used in Limming, Painting, Tricking, and Blazon of Coats, and Arms, with divers other most delightfull and pleasurable observations, for all young Gentlemen and others. by Henry Peacham

I like especially the printer's address: Printed for Richard Thrale, at the signe of the Cross-Keys in Pauls Church-yard. Can't miss him!

The next-oldest book but with its original/contemporary binding would be a 1702 selection of Pascal's works (Paris, Guillaume Desprez), Pensées de Pascal sur la religion, & sur quelques autres sujets.

An interesting topic for a Fine Press Forum.
My oldest books are bibles. All in Latin (Which I don't read)
I haven't learned how to upload images of them here. Some are in my mamber gallery
One is printed in Lyon for Koeberger in 1520
another is from Switzerland, Froben 1514
An incunable, by Arrivabenus, Venice 1487-88
There are also two manuscript bibles:
a New Testament from Oxford, DeBrailles 1260
a 240 page fragment from Soissons Ateliere Paris 1220

>10 cbellia: Well, now. I am impressed, sir! Nice collection.

I am editing my previous post:
This is the oldest book in my library it was given to me about 74 years ago. It is my oldest possession.

>12 cbellia:
What is it? When was it published?
Image too small to see these details.
Thanks.

>13 wcarter:: Its really not much of a book. It is a Missal given to me by my uncle (a priest) for my First Communion. I studied it very carefully in order to be able to be his alter boy when he came to town. It is made of cheap (not acid free paper) and could not be rebound. I made the elegant clam-shell box for it.
