From a book I bought many years ago "Fly Patterns, and International Guide" written by Taff Price and illustrated by George Thompson (Blandford Publications, UK), I became aware of three European Regions that seem to have a "Tenkara" style history that goes back a few hundred years.
The Valasesiana Trout Flies of the Sesia Valley in the Piedmont region of Northern Italy. The Ossolina Trout Flies of the Ossola valley to the west of the Sessia Valley. The Bartellini Spiders of the Oreco, Po, and Stura Rivers near Turin; that are very similar to trout flies used is the Spanish Pyreness.
Walter Bartellinin of Turin is crdited with creating with over 40 of this style of trout fly patterns.
