Aristodemo Costoli (1803–1871) was an Italian sculptor who spent his entire career in the city of Florence. He is also known for attempting in 1843 to clean and conserve the famed Renaissance-era sculpture David by Michelangelo; unfortunately his hydrochloric acid cleaning solution removed the stone's waxy protective coating and left the surface pitted and porous.[1][2] His students included Emilio Zocchi, Girolamo Masini, Augusto Rivalta and his son Leopoldo Costoli.
The David in Florence's Accademia is young Michelangelo's masterpiece.
...a masterpiece of throbbing vitality.
