It gets its name from the inventor, Latino Orsini. The radio latino can be considered a kind of geometric square. It was a general purpose instrument that could be used for a variety of angular measurements as well as depth and inside dimension measures.

High Quality Content by WIKIPEDIA articles! A radio latino is a measuring instrument used in surveying and military engineering starting in the 16th century. It gets its name from the inventor, Latino Orsini. The radio latino can be considered a kind of geometric square. It was a general purpose instrument that could be used for a variety of angular measurements as well as depth and inside dimension measures. The slider (blue in the diagram to the right) could move along the central rod, causing the deltoid formed by four other rods to change shape symmetrically. The end points of the rods had sights on them, allowing various sight lines to be defined. The central rod was graduated with various scales. These scales allowed the angles between the end rods (represented by the red lines in the diagram) to be determined as well as the angle with its vertex at one end of the main rod and sides (represented by the green lines in the diagram) through the outer joints of the rods.
