Andrea Cagnetti (born 16 March 1967 in Corchiano, Viterbo), known in the artistic world as Akelo, is an Italian goldsmith, designer, and sculptor. He is known for dedicating himself to the research of the ancient techniques used in metalworking. After having obtained a diploma at the Ronciglione state secondary school, with a concentration in scientific studies, Akelo transferred to Rome, where for several years he worked as a graphic artist while continuing to pursue his in-depth studies of texts and documents relating to ancient goldsmithing, metallurgy, and alchemy.

Combining this theoretical understanding with extensive experimentation on materials and techniques, he creates gold objects and makes sculptural objects out of gold, bronze, and iron, using the artistic name of Akelo (from Achelous, Greek god of the waters).

In 2010 the artist created the bronze sculpture "Hope" for the Robert Bresson Prize, given every year at the Venice Film Festival.

Andrea Cagnetti lives in Corchiano, where he also writes scientific articles on the techniques used in goldsmithing.
