Hagiography for yourself? [closed]
Solution 1:
Hagiography definitely carries a sarcastic tone when referring to someone doing their own. By its original definition, it's a writing about the lives of the saints. Hagio- is derived from the Greek for saintly and -graphy for writing.
Canonization for sainthood typically takes place after one's death. And, it's done by others as a celebration of the goodness/sanctity of that person. (It's also the origin of the term The Devil's Advocate)
Many religions have their own process, but it's rare that someone would present their own hagiography. It can be argued that presenting your own would invalidate your sainthood as it's commiting the sin of pride.
So given the irony, I'm going to say, yes, it's sarcastic.
But, to drive the point home (and bowing to social pressure), I'd change your example sentence to:
He continued his autohagiography.
