Tavola Doria
La Tavola Doria is a painting depicting the central part of the famous mural painting of the Battle of Anghiari by Leonardo Da Vinci, created between 1503 and 1505.
The artist is unknown and is widely believed to be a copy of a 16th-century Tuscan artist, perhaps Poppi. A 2013 article suggests the name Giovanni Francesco Rustici.
In Leonardo's sketches for the Battle of Anghiari, the weapons used do not include daggers, knives, or small, common bladed weapons, but only extremely long spears, which are essential in establishing the composition and background of the work. These spears are masterfully used in the graphic division of the drawings, which can be viewed at the Galleria dell'Accademia in Venice. A thorough understanding of the sign present in a work is crucial for its attribution.
