Fabio Colonna

He was the son of Girolamo Colonna, a philologist and antique dealer who was also editor of the fragments of the Latin poet Ennius. As a youngster he became proficient in Latin and Greek before attending the University of Naples, where he graduated in law in 1589. He suffered from epilepsy, which prevented him from practicing law, so he turned to studying the ancient authors of medicine, botany and natural history. He noticed numerous errors and omissions in Dioscorides' Materia medica, but his commentary on that work is now lost.

In the period between 1606 and 1616, Colonna studied fossils, finding evidence for their organic origins.

The publication of his first works on botany, such as De purpura made him a celebrity among naturalists and one of the first members of the Accademia dei Lincei in Naples, which had been founded by Federico Cesi in 1612. In the following years, his academic activity at the Lincei was intense, including the writing of the Apiario and the Tesoro Messicano that the Lincei published in 1625 and 1628.

Colonna became interested in the recently invented telescope and microscope, corresponding with Galileo Galilei and other Lincean academics on astronomy.[2]

In 1625 he published two drawings, Apiarium and Melissographia, regarding bees.

Colonna was also interested in music, inventing a stringed, meantone temperament instrument, the pentecontachordon, having 50 strings in which the octave is divided into 31 parts and the tone into 5 parts.

Colonna was a pupil of Ferrante Imperato and a friend of Giambattista della Porta and Bartolomeo Maranta.
