If it's time for explanations of our stories (except by those in the tiebreaker poll, obviously), I ought to explain mine. To be fair, Wiki will tell you who Urania is, but that doesn't help with the story.
Urania is the Muse of Astronomy. The Muses are the nine daughters of Zeus and Mnemosyne. The reason why Urania's mother would be humiliated by Urania's supposedly poor ability to recall what's happened is that Mnemosyne is the personification of memory.
Urania is on trial for selling her inspiration to humanity, thereby giving them a greater desire to unlock the secrets of the heavens - i.e. the universe - than they would otherwise be allowed. (This is where the title comes in**, a talent being a measure of weight or, in this case, money.)
She is innocent of this, but only because she is guilty of something greater: forcing a love of astronomy onto humanity. She has done this to teach her father a lesson for his sex addiction (which she calls
his swanning around) by giving humanity the will to explore, and eventually "conquer", the "heavens", losing the desire to worship the gods of Olympus as they do so.
Whether this is justice or revenge, who can truly know?
** - Actually, the title came first and is a slight rearrangement of the title of Sheridan Morley's biography of Noël Coward,
A Talent to Amuse. The phrase just popped into my head on Monday - perhaps someone on the radio said it - and the story seemed to spring straight from that.
