Chelidonij Musophili_, in quarto) in thirty-seven smaller ones. After this Durer was caught up by the Emperor Maximilian and set to work on some of the various ambitious projects for illustrating his reign, as to which more will be said later. His later bookwork includes a Crucifixion and S. Willibald for an Eichstatt Missal (Nuremberg, H. Holzel, 1517), some large designs for the _Etliche vnderricht zu befestigung der Stett Schloss vnd flecken_ (Nuremberg, 1527), and his own book on the Proportion of the Human Body, which was issued both in German and in a Latin translation by Camerarius. Several borders and illustrations formerly ascribed to Durer are now attributed to one of his pupils, Hans Springinklee, who lived in Durer's house at Nuremberg, where he worked from about 1513 to 1522. Most of Springinklee's bookwork was done for Anton Koberger, who published some of it at Nuremberg, while some was sent to the Lyon printers, Clein, Sacon, and Marion, who were in Koberger's employment. A border of his design bearing the arms of Bilibaldus Pirckheimer is found in several works which Pirckheimer edited (1513-17). In a _Hortulus Animae_, printed by J. Clein for Koberger at Lyon, 1516, fifty cuts are by Springinklee. The _Hortulus Animae_ was as popular in Germany as the illustrated _Horae_ in France and England. In 1517 another edition appeared with Erhard Schon as its chief illustrator, and only a few of Springinklee's cuts. The next year Springinklee produced a new set of cuts, and Schon's work was less used. Springinklee and Schon were also associated in Bible illustrations printed for Koberger by Sacon at Lyon, and to Springinklee are now assigned two full-page woodcuts in an Eichstatt Missal (H. Holzel, Nuremberg, 1517), and a border to the _Reuelationes Birgittae_ (F. Peypus, Nuremberg, 1517), formerly ascribed to Durer. A woodcut of Johann Tritheim presenting his _Polygraphia_ to Maximilian, formerly attributed to Holbein as having been printed at Basel (Adam Petri, 1518), is now also placed to the credit of Springinklee, who, moreover, worked for the _Weisskunig_ and probably for other of the artistic commemorations of himself which Maximilian commissioned.
