Actually - what did the phrase really mean? I've just tried translating it on the assumption that it was Italian - or Spanish - or Portuguese - and I seem to be stumped, or at least the computer is.
I think it's the start of a blank verse poem, chastising a child for having too wild an imagination, and implying the consequences will be grave. I feel like it's been written already - maybe it's something I should work on.
[Breadmaster] It came from the Oxford Dictionary of Quotations. To summarise their explanation, on seeing Raphael's St Cecilia at Bologna, c.1525, Antonio Allegri Correggio is supposed to have exclaimed, "Son pittore ancor io!" meaning, "I, too, am a painter!"
On the other hand, he may just have seen through the window that Io had broken loose from its orbit and was hurtling towards the Earth. In a blind panic, he screamed, "For pity's sake, child, tie down the moons of Jupiter!"
Ah, of course, I must have temporarily forgotten! Maybe we should have a game of highly promising openings to non-existent stories/novels/plays/poems/songs, although I don't know if it would work/has already been done...
[Penelope] I graciously permit you to use the line in question, provided I receive full acknowledgement! I thought it might be something about humanity's hubris and folly, but I think your explanation is better and much sadder. Reminds me of the more whimsical Calvin and Hobbes stories.
