bears his imprint is apparently “Geberi philosophi ac alchimistæ maximi, de Alchimia, libri tres,” March, 1529. Martin Schott’s distinct device is found in at least three books of the date 1498, including Matheolus’ “Ars memorativa,” and was used by him until 1517. It was also used by his son, Johann Schott, about 1541, the same printer using seven or eight other Marks, all more or less distinct, at different periods. The first book bearing Martin Schott’s name is dated 1491, and he continued printing until 1499; while his son was in business from 1500 to 1545. Equally distinct is the accompanying example--one of several--used by Johann Knoblouch, which is found in the majority of the books printed by him from about 1521 to 1526, notably several works by Erasmus (_e.g._ “Moriæ Encomium,” 1522, and the “Novum Testamentum,” 1523). The father started in 1497, and was succeeded by his son, who continued the business until 1558. The Mark, it may be mentioned, is a somewhat atrocious pun on the owner’s name, which is the German for “garlic,” with the seed pods of which the figure emblematically representing Ignorance ascending from darkness into light is encircled; this Mark is generally surrounded by mottoes in Greek, Hebrew, and Latin.

RB] Although Reinhard, or Renatus, Beck was only in business for about eleven years, 1511-1522, he had several Marks, which differed chiefly in their extraneous ornament, as will be seen from the accompanying examples. Two books, _sine nota_, which Mr. Quaritch assigns to Beck’s press, of the date 1490, are remarkable for the large number of woodcuts which they contain, relating principally to plants, animals, gardening operations, rural architecture, so that the Mark of “ein wilder Mann” is so far in keeping with the nature of his publications. Fourteen or fifteen Marks, several of which are only variations of one type, have been identified as having been used by Wolfgang Köpfel (whose surname sometimes appears in its Greek translation of Cephalæus) between 1522 and 1554: the most remarkable, of which we give a reproduction, appears to have been used very rarely, notably in “Zehn Sermones” of Luther, 1523; a much commoner type is the smaller example, which appeared in various books issued between 1526-1554. Georg Ullricher von Andlau, 1529-36, confined himself to one type (see p. 1), that of the Cornucopia or Horn of Plenty, of which there are seven variants. The more elaborate of the two Marks of Matthias Biener, or Apiarius, 1533-36, appears in Oecolampadius’ “Commentarius” on the Prophet Ezekiel, 1534, and is an evident pun on the printer’s surname. Several of the dozen Marks used by Craft Müller, or Crato Mylius, 1536-62, are exceedingly bold and
