... Was Shakespeare a crypto-Catholic? (Hat tip, Rus Bowden.)
Weirdly enough, in article XII, he beseeched his parents to pray for his soul's delivery from purgatory, although his parents were by then dead.
No, what would be weird is praying to them if they were alive. Presumably, he thinks them in heaven and prays for their intercession, since he expects to land in purgatory himself.
