I found following sentence from one of books that I've recently read. What I cannot understand is why they have used past participle to talk about some events that we know the year. I mean, though it happened in 1884, they haven't used past tense.

Thus, please tell me whether that sentence is grammatically correct or not and whether and is it the natural way of explaining such ideas.
