ancient magic & Dumbledore WAS Potters

No: HPFGUIDX 30650

In SS/PS, Dumbledore claims ignorance about how Harry survived. That 
may not have been the case. He probably knew this "ancient magic," 
since he is probably the same person who invokes the ancient magic 
that protects Harry under his family's care (or was it Lily, the 
charms expert...)

But Dumbledore didn't exactly want LV to know what was protecting 
Harry, and it worked, sort of. It took LV 13 years, plus close 
contact in SS to figure it out. 

This begs this the questions of why wouldn't he share with 
McGonagall? The result of years of being cautious because of LV? Just 
because everyone is celebrating doesn't mean Dumbledore is ready to 
take risks.

In the first chapter, Dumbledore does say that he has no idea how 
Harry survived. And yet, by the final chapter of SS, Dumbledore is 
able to give Harry an answer about how he lived (i.e. Lily's love). 
How did he figure this out in the course of a year at Hogwarts?

Well, he didn't have only a year, remember, in the first chapter, 
Harry was only a year old.  By the time Dumbledore tells Harry he 
lived because of Lily's love, Harry was 12.  I guess by then, he had 
it figured out!
