Bartolomeo della Rocca

Bartolomeo della Rocca, also known as Cocles (March 19, 1467 – September 9, 1504) was a scholar of chiromancy, physiognomy, astrology, and Geomancy who lived in Bologna, Italy during the rule of the Bentivoglio.

Alessandro Achillini was a promoter of Cocles.

Ermes Bentivoglio had Cocles assassinated because of his prediction that Ermes would die in battle.

His main work, the Compendio of Fisiognomica ("Compendium of Physiognomics"), was published in 1553 in Strasbourg.
