There are but two instances, quoted by Lord De Tabley, of the inscription directly referring to the _book-plate_. Both are foreign, and date about the middle of the last century. One is _Symbolum Bibliothecæ_ of John Bernard Nack, a citizen and merchant of Frankfort;[2] and the other, _Insigne Librorum_, etc., quoted from the work of M. Poulet Malassis. Lord De Tabley thinks that the _Symbolum_ of Herr Nack is simply a trade card; but he founds this conclusion on the supposition that Herr Nack was a book-dealer, and that the scene depicted on his book-plate was, in fact, his shop. In my opinion, we have in this book-plate a representation of a portion of Herr Nack's library, in which Minerva(?) is seated, using the books thereof. A gentleman in eighteenth century dress, who may, likely enough, be Herr Nack himself, addresses himself to the goddess, and explains--as he points to the outer scene, which shows us ships and merchandise--that, whilst following his trade as a merchant, he still has time to devote some attention to literature. In any case, these and the few other instances there may be of the inscription referring to the book-plate and not to the book, seem hardly sufficient to make _ex libris_ a good name for book-plates in general. Our ancestors, of degrees more remote than grandfather, do not appear to have referred to book-plates at all, so we are unable to learn by what name they would have called them. Pepys, in 1668, speaks of going to his 'plate-maker's,' and there spending 'an hour about contriving' his 'little plate' for his books. This 'little plate' still exists, and is a characteristic one; it shows us the initials 'S. P.,' with two anchors and ropes entwined. But we shall speak again of this, and Sam's other book-plates, later on. [Illustration: SIR THOMAS ISHAM'S BOOK-PLATE, BY DAVID LOGGAN.] David Loggan, a German born, and an engraver of some note, has, in writing to Sir Thomas Isham in 1676, a no more concise name for Isham's book-plate than 'a print of your cote of arms.' Loggan, as a return for many favours, had sent Sir Thomas a book-plate designed and executed by himself. 'Sir,' he says, in the covering letter, 'I send you hier a Print of your Cote of Armes. I have printed 200 wich I will send with the plate by the next return, and bege the favor of your keind excepttans of it as a small Niew yaers Gift or a aknowledgment in part for all your favors. If anything in it be amies, I shall be glade to mend it. I have taken the Heralds painter's derection in it; it is very much used amongst persons of Quality to past ther Cotes of Armes befor ther bookes instade of wreithing ther Names.' The 'Heralds painter' was, unfortunately, wrong in his treatment of the Isham 'coat,' and so Loggan's work, artistic as it might be, could not be acceptable to Sir Thomas, to whom a mistake in the family escutcheon was no light matter. This he evidently told David, who, a few days after, writes to him again:--
