This list's threads have been a great help in my unrelenting effort to understand the BotNS and UotNS, which I have just finished reading for the first time. I live in Brazil, so don't have ready access to much of the supporting content that would otherwise help me, such as Lexicon Urthus etc., and therefore this list has been particularly useful. Thanks!<div>
<br></div><div>Unfortunately, the archives are so extensive that I lack the will to sift through them all. Consequently, I don't really know if the remark I'm about to make is original or not, though I suspect it isn't, for it's quite obvious. Anyway, while searching for "avern" on google, I stumbled upon lake Avernus, which is a real lake in Italy. In addition to "Avernus" meaning "birdless" (apparently due to ancient Romans' belief that birds that flew over this lake would die), and to this lake being considered a sort of gate to Hades (and therefore a place in which many dead people lie), it is also the abode of the "mythological" Cumean Sibyl. The "Lake of Birds" is thus obviously lake Avernus.</div>
<div><br></div><div>This raises some questions. What are the gardens in the Botanical Gardens - illusions, reconstructions of past landscapes, or, as I'm more inclined to believe, those landscapes themselves? If the Lake of Birds is Avernus itself, in which time period is it? Ancient Rome? Or is it possible to experience many different periods of time in the Lake of Birds, as it appeared to be in the Jungle Garden? What I thought most interesting, though, was the part in which the old man with the boat (Severian's grandfather?), says that there is a pipe that links the Lake of Birds to Gyoll, and that apparently that was the reason why this lake does not dry up. Is that Wolfe giving us an early clue that, in his world, the future can determine the past, and not only the other way around? Would lake Avernus dry up in ancient Rome, if the pipe that connects it to Gyoll would clog up in the future? Given the general theme of Wolfe's work, that would "make sense".</div>
