Sometimes my omniscience runs away with itself. Two or three years back, I dreamt of being in a bookshop, and finding a 1496 edition of Nigidius Figulus. Who? Well, I consulted various dictionaries, and asked my Cambridge roommate, now a Professor of Classical Archaeology at Cornell, and we drew a blank. A year or so later, I found out who he was, a friend and correspondent of Cicero's, an expert on augury! His works are lost, so an incunabula wouldn't have existed!
I'd love to know how he got into my dreams!
And there's an off-topic post for you, which even Coffee couldn't beat!
