A book of some interest exhibited in the glass case is Theseus Ambrosius: _Introductio in Chaldaicam Linguam_ (1539). It is of interest as being the first book in which Syriac types were used, and next as containing a specimen of spirit-writing dating from the sixteenth century. It seems that a question having arisen about some property of a deceased lady which was supposed to be concealed, it was resolved to evoke a demon to answer the question. A sheet of paper and a pen were placed on the table, and the proper incantation being gone through, the pen rose up, without anyone seeing the hand that held it, and wrote the characters of which Ambrosius gives a fac-simile, and which, unfortunately, no one has been able to decipher. I am informed that in the copy of this book in the Bodleian Library this particular leaf is pasted down, the “devil’s autograph,” no doubt, being deemed uncanny. But to enumerate our rare books, or even our fifteenth-century books, would be tedious, if it were possible. I must not, however, omit to refer to some fine specimens of binding, most of which are in the Quin collection. We have six of Grolier’s books[133]--namely, Erasmus: _Pacis Querella_; Palladius: _Coryciana_; Greek Psalter (Aldus); _Il Nuovo Cortegiano_; _Cynthio degli Fabritii_; _Della Origine delli Volgari Proverbi_; and (perhaps the finest) Guilelmus Tyrius: _Belli Sacri Historia_ (folio). Of Maioli we have--Ori Apollinis _de Sacris Notis et Sculpturis_, Catullus, Tibullus, and Propertius; one by Monnier--_Spaccio de la Bestia Trionfante_; and last, but not least, a copy of _Quintus Calaber_, which belonged to Henry II. of France and Diane de Poitiers. There are in the Library a few interesting objects other than books which deserve notice. The satchel of the _Book of Armagh_, and the shrines of the _Books of Dimma and Mulling_, have been already noticed. A very remarkable object is a Mosque Staff, presented by Dr. Jolliffe Tufnell, who professionally attended Omar Pasha’s army in 1854. Such a staff is used where there are no mosques, and being set up on a temporary structure, as a heap of stones, it represents a mosque. On each of the four sides is carved a sentence from the Koran. “I am in the house of the Lord.” “Evil and good are sent by God; be content with your lot.” “Every day we offer our prayers to Thee.” “Forgive us all our sins.” “With heart and soul we believe in Thee.”
