The Trail of My Wikipedia Reading Today
Being in Florence, Italy has led me on a trail of hours of reading while Eva & the kids slept:
Leonardo da Vinci -> Michelangelo -> the Medici -> Italian Renaissance -> Dante -> Guelphs and Ghibellines -> Holy Roman Emperor -> Charlemagne -> Franks -> Lombards -> Germanic peoples -> Proto-Germanic -> Proto-Indo-European
That's just the main line, of course. Side lines have included the Second Council of Nicaea, Vatican I and Vatican II, Protestant Reformation, Concordat of Worms and more.
Lesson: Wikipedia in general, and Leonardo in particular, can be dangerous.
