This commission was inspired by my painting Davida, a tribute to the female version of the statue of David. Davida was strong, proud and vulnerable. Lisa, the woman who hired me to paint her in the nude loved my painting so much that she wanted to show off herself in the same way. At 45 and with 2 kids, she has a body that she takes great pride in and wanted to capture it forever. It was a gift for her husband. I called it thirteen because of a small tattoo on her left breast. She said it was to memorialize a song that was important to her but offered no other explanation. I really wish I knew.
