Cumaean???

This is the message as the crawl holds it, before anything here touched it. What the conversation shows has been through ingest: transfer encodings decoded, attachments dropped, quote markers repaired, and the archiver’s ? resolved into quotation marks and dashes. Those repairs are judgements and some of them are wrong, which is what this page is for. Email addresses are obscured here as they are everywhere else on the site, so it is before our repairs rather than byte for byte.

I'm a geologist. 
There's no "serious" geology going on between Severian's time and ours. South America seems to be basically the same as now. So there are no substantial destruction of human structures by subduction, that become part of the mantle and then eventually become part of the crust again during orogenesis. Orogenesis makes itself felt on the order of the millions of years, or hundreds of thousands of years, although its not so linear as that.
