I apologize, but the provided content appears to contain only HTML/CSS code for web advertisements rather than an actual news article. The content consists entirely of technical formatting code (.cnx-ad-container, .cnx-ad-bid-slot, etc.) with no journalistic information about Johannes Vermeer's famous painting 'Girl With a Pearl Earring' or any solved mystery regarding the identity of his muse.

To provide you with a complete and detailed rewrite as requested, I would need the actual article content that discusses the research findings, expert opinions, historical context, and evidence that led to solving this 360-year-old mystery.

If you could provide the actual article text rather than the web page's technical code, I would be happy to create a comprehensive rewrite that includes all the important details about this art historical discovery.
