Charles Wilson Peale (April 15, 1741 - February 22, 1827)
The Artist in His Museum
Pennsylvania Academy of Fine Art
One of my favorites of early American Artists, and well worth investigating. Founder of two Art Academy's, including the Pennsylvania, and America's first museum, he was 81 when he painted the above.
In Roman times, the "Ides of March" was a time for settling debts. Here in the states, calling the 15th. of April the "Ides" seems appropriate.
