Maximilian had an interest in the disease, which led him to establish eight hospitals in various hereditary lands. He also retained an interest in the healing properties of berries and herbs all his life and invented a recipe for an invigorating stone beer. In Glarus, Switzerland, he is still commemorated for his receipt against plague. Maximilian had an interest in archaeology, "creative and participatory rather than objective and distancing" (and sometimes destructive), according to Christopher S.Wood. His chief advisor on archaeological matters was Konrad Peutinger, who was also the founder of classical Germanic and Roman studies. Peutinger commenced an ambitious project, the Vitae Imperatorum Augustorum, a series of biographies of emperors from Augustus to Maximilian (each biography would also include epigraphic and numismatic evidences), but only the early sections were completed. The search for medals ultimately led to a broad craze in Germany for medals as an alternative for portraiture. At the suggestion of the emperor, the scholar published his collection of Roman inscriptions. Maximilian did not distinguish between the secular and the sacred, the Middle Ages and antiquity, and considered equal in archaeological value the various searches and excavations of the Holy Tunic (rediscovered in Trier in 1513 after Maximilian demanded to see it, and then exhibited, reportedly attracting 100,000 pilgrims), Roman and German reliefs and inscriptions, etc. and the most famous quest of all, the search for the remains of hero Siegfried. Maximilian's private collection activities were carried out by his secretary, the humanist Johann Fuchsmagen, on his behalf. Sometimes, the emperor came in contact with antiquities during his campaigns – for example, an old German inscription found in Kufstein in 1504, that he immediately sent to Peutinger. Around 1512–1514, Pirckheimer translated and presented Maximilian with Horapollo's Hieroglyphica. The hieroglyphics would be incorporated by Dürer into the Triumphal Arch, which Rudolf Wittkower considers "the greatest hieroglyphic monument". Maximilian's time was an era of international development for cryptography. His premier expert on cryptography was the Abbot Trithemius, who dedicated Polygraphiae libri sex (controversially disguised as a treatise on occult, either because its real target audience was the selected few such as Maximilian or to attract public attention to a tedious field) to the emperor and wrote another work on steganography (Steganographia, posthumously published). As practitioner, Maximilian functioned as the Empire's first cipher expert himself. It was under his reign that proven use of encrypted messages in the German chancellery
