A donkey - probably not Saint Martin's.He was a thoroughly peregrinatious type, constantly travelling throughout his diocese on his donkey and this aspect of his life is remembered in the Chemins de Saint Martin pilgrim trails. He is credited with bringing from Hungary the Chenin Blanc grape used in Vouvray and Montlouis, either side of the Loire near Marmoutier. Consequently, he is not only the patron saint of beggars, soldiers, tailors and equestrians, but also vintners, innkeepers, alcoholics and ... geese.
Heading for the vines?His donkey gets its own 15 minutes of fame though. The story goes that it was partial to eating the grape vines that Saint Martin had brought back from Hungary. Saint Martin noticed that the grapes these vines produced made better wine that those from the vines the the donkey couldn't reach, and the vines were more robust and healthier. Thus the practice of pruning vines was invented and has been practiced ever since.
(Yesterday was Saint Martin's Day, the anniversary of his burial in Tours in 397.)
