This is our logo, sort of. Our wordmark sits over Sandro Botticelli's Birth of Venus, an early Renaissance painting that I love. Among most other Renaissance paintings, this painting is interesting in its subject matter (Greek mythology) and style -- you have to see it in person ... it's amazing.
Anyway, we don't claim any copyright to the image, as it's part of the public commons. Sorry, Mr. Botticelli, your copyright expired at least a few minutes ago.
