Radio Latino

From Inventions

Name coined by the inventor associating his own name, Latino, with the now widespread term radio (see radius astronomicus).

Instrument for architectural and topographic measurements. Invented and described by the condottiero Latino Orsini (1583), the radio latino (named after its inventor) is a universal instrument designed to carry out a wide range of functions. When sheathed in its case it looks like a dagger, but when opened it serves the same functions as the ancient radio greco, the cross-staff (see) or balestriglia, the Great Rule of Ptolemy, the quadrant, the folding square and the gunner's quadrant. When fitted with a compass in the handle it was used mainly for surveying purposes.

Orsini, Latino. "Trattato del radio latino: istrumento giustissimo et facile più d'ogn'altro per prendere qual si voglia misura et positione di luogo tanto in cielo come in Terra, il quale oltre alle operationi proprie sue fa anco tutte quelle della gran regola di C. Tolomeo et dell'antico radio astronomico". In Roma, appresso Vincentio Accolti, 1583.
