Leonardo da Vinci started painting the Mona Lisa, also known as La Gioconda, around the year 1503. However, he worked on it intermittently over several years until his death in 1519. So, it is difficult to determine exactly how long it took him to complete the painting.

There are different theories regarding the identity of the woman who posed for the Mona Lisa. Some art historians suggest that she may have been Lisa Gherardini, the wife of Florentine merchant Francesco del Giocondo. However, this theory is not widely accepted, and the true identity of the model remains a mystery.

In addition to being a painter, Leonardo da Vinci was a polymath and excelled in various fields. Here are some of his other professions:

1. Sculptor: Da Vinci sculpted several artworks, although only a few of them survived to this day, including a few unfinished sculptures like the famous "Horse and Rider."

2. Architect: He designed several architectural projects, including plans for ideal cities, fortresses, and even military devices.

3. Engineer: Da Vinci worked extensively as an engineer and made significant contributions in various fields such as civil engineering, hydraulics, and mechanics. He also designed various groundbreaking inventions that were far ahead of their time, including flying machines and armored vehicles.

4. Scientist: Da Vinci made remarkable contributions to the fields of anatomy, paleontology, and botany through his meticulous observations and detailed sketches.

5. Writer: He was also a prolific writer, contributing to various scientific and artistic studies. His notebooks, containing sketches and writings, provide insight into his thoughts and ideas.

These are just a few examples of the diverse talents and professions of Leonardo da Vinci.
