Lady with an Ermine, Leonardo da Vinci's portrait of a patron's mistress holding the symbol of her lover's family, is perhaps his most beautiful painting. But...is that what ermines really look like?

The time-traveling hero, Mario Ravelli, develops a unique friendship with Leonardo da Vinci during a vacation from 2523 A.D. The story of how Mario's pet becomes the lady's ermine makes for an intriguing, entertaining journey to Renaissance Italy, and gives a unique look at the work and the creative process of a great master.
