This picture, by Giotto, is a small part of the sumptuous Scrovegni Chapel in Padua. It shows the Wedding at Cana.
And as a rather charming article by Jeremy Parzen reminds us, transforming water into wine goes well beyond a mere demonstration of awesome skillz.
According to Jewish tradition, a marriage cannot be performed without a blessing over the wine. Had Jesus not transformed the water into wine, there would have been no marriage that day.
Which reminded me that I really need to get back to Padua, not only to revisit the Scrovegni Chapel, but also to see the refurbished botanic gardens, the type specimen of the genus.
