This is a very interesting episode in Philippine history.
Filomena Almarines was supposed to have been a saintly woman who lived in the town of Binan, Laguna, in the early twentieth century. A vendor, Filomena was the daughter of a poor tenant farmer. Not much is known of hear early life except that she died in 1938, her father following suit some seven years later. Since most people were poor back then, many had to share the same graves when they died. This is still a very common phenomenon today; I've heard of families so poor who were all interred in the same nicho (niche); probably a bit of a shock to our middle class sensibilities, but ultimately a pragmatic move (it also saves the remaining members from paying the priest extra for his stipend). Anyway, as they were preparing to clear Filomena's niche, lo and behold, she was discovered to be incorrupt!
A local man, wizened and much respected by the townsfolk, discovered that there was water inside the niche. Perhaps he read this is a supernatural omen, but something drove him to wash his eyes with it; soon enough, the blind man began to see once more. In popular religious fashion, Filomena's mortal remains were exhibited in a glass coffin; some cautioned that the 'holy water', if holy indeed it were, could be a breeding ground for many, untold diseases; but still people flocked to Filomena. There were even reports that new quantities of water began to form inside the locked, glass coffin.
Eventually it was decided that the body was to be re-interred in the ground, but the parish priest refused, because the chosen site was formerly a grazing ground for beasts. Thus, the people sought the help of the Aglipayan priests (officially, the Iglesia Filipina Independiente) for the required blessings. Today it is said that the body of Filomena Almarines is still under the custody of the sons of Aglipay; there are rumors too that the body, when it was exhumed in the 1970s, had finally corrupted; but her eyes, it was said, remained clear as ever.
EDIT: I found the link to where I originally found this. Mr. Alex Castro has one of the most unique photos in his Flickr account, many of them of a religious background. I highly recommend going there to check out his stuff-- you won't be disappointed!
