Mona Lisa, Mona Lisa ...

In 500 years, do you think people will be talking about anyone or anything done this year? Well, back in 1506, Leonardo da Vinci finished a painting that came to be known as the "Mona Lisa.'' Five centuries later, she's still in the news. This time, it's a report of researchers studying 3-D images who say her enigmatic smile may refer to a pregnancy. Something about a fine veil around her shoulders refers to a garment women of the time wore when they were expecting.

Isn't that amazing? A painting that old still fascinates modern man. She's been the subject of a Nat King Cole song classic and played a key role in the novel/film "The Da Vinci Code,'' among many other cultural references. Talk about longevity!

Maybe it's a tribute to the ambiguity of art. Everything is not all that it seems. And people will ponder it for years to come. Perhaps there's a lesson here for in-your-face communicators: All that bluster won't last five minutes, not to mention five centuries.
