Does anyone know of any information on a painting called "The Death of Cleopatra" by Jacques Louis David or possibly one of his students or at least a neoclassic painter, probably French, in the style of David.

Is this the one you are speaking of?:

Very nice find but it is the one by Jean Andre Rixens in 1874 hanging in Toulouse Museum. Would welcome any others esp. Early 17th - Early 19th century. Exs,

Can'd find:
Suicide of Cleoptra : 1621 : Giovanni Fransesco Barbieri
The Death of Cleopatra: 1660 : Guido Cagnacci
Jean-Leon Gerome's from 1824

Thanks Though

I did not find any by David himself, and that one kept coming up in my searches -so just thought I'd ask.

Sorry I couldn't help more :o
