That's Richard FitzAlan, the tenth Earl of Arundel. He fought in France and Scotland and commanded the English army for awhile. He also was incredibly rich. He died in 1375 or 1376 -- accounts differ. In their tomb, he and his wife are depicted with their dogs sleeping at their feet
Philip Larkin wrote a lovely poem about this tomb that ends with these lines:
Our almost-instinct almost true:
What will survive of us is love.
Thomas E. Ricks covered the U.S. military for the Washington Post from 2000 through 2008.
