Despite complaining of his lack of a formal classical education, Dürer was greatly interested in intellectual matters and learned much from Willibald Pirckheimer, whom he no doubt consulted on the content of many of his images.Corine Schleif (2010), "Albrecht Dürer between Agnes Frey and Willibald Pirckheimer", The Essential Dürer, ed. Larry Silver and Jeffrey Chipps Smith, Philadelphia, 85–205. He also derived great satisfaction from his friendships and correspondence with Erasmus and other scholars. Dürer succeeded in producing two books during his lifetime. The Four Books on Measurement were published at Nuremberg in 1525 and was the first book for adults on mathematics in German, as well as being cited later by Galileo and Kepler. The other, a work on city fortifications, was published in 1527. The Four Books on Human Proportion were published posthumously, shortly after his death in 1528.
