Three extensible legs that, with the horizontal base inv. 2538, formed a tripod for holding one or more measuring instruments. Each leg consisted of two square-section rods and two moving and telescoping parts. They carry steel tips to be driven into the ground, and a threaded section for screwing into the corresponding openings in the horizontal base. The ornamentation suggests the item formed part of a box of mining instruments. Brought to Florence from Germany by Prince Mattias de' Medici in the first half of the seventeenth century.
