Most instruments used for surveying work in mines were made in Germany. The specimens at the Museo Galileo of Florence were brought to Tuscany by Prince Mattias de' Medici (1613-1667). These finely chiseled and gilt artifacts included compasses, protractors, squares, magnetic compasses, etc., created for or "adapted" to mine surveying—still a relatively new technique in the sixteenth century. The instruments from Saxony and Tyrol, the birthplace of mining science, were crafted with special attention to their esthetic appearance.
