卢浮宫表示，当取下作品后——这是一幅木头上的油画，绘画部的一位馆长在其背面发现了两幅很难看出来的素描，内容分别是一匹马的头部和半个骷髅。

"When taking down the work, an oil on wood, a curator from the paintings department noticed two barely visible sketches on the back, representing a horse's head and half a skull," the Louvre said.

这个看法一经提出，画作所在的巴黎卢浮宫的专家们即刻表示反对。

The claim was immediately disputed by experts at the Louvre in Paris, where the painting is on display.
