Melkor and Sauron

 It is interesting to see a Lord of the Rings group that is named for two of the bad guys of Middle Earth. The group is more focused around the tales of the Second Age, as collected within works such as The Silmarillion, and Tolkien's literary legacy, rather than the cinematic interpretation thereof. Another great feature here, is the inclusion of fan art, mostly of Melkor and Sauron, who were described at beautiful and elf-like in their appearance. So, expect a decidedly dark art and elf-noire aesthetic. There are occasionally posts about Lord of the Rings and the Third Age, but not that much. It's a great space for Tolkien superfans.

Animals in Art through History

Is it my imagination or are cats and cat art disproportionately well represented in this space? Not that I'm complaining. Quite the opposite in fact. The featured art ranges from ancient history to works just completed, and shows birds, snakes, dogs, horses, rabbits, otters, oxen, camels, lobsters and even dragons amongst its subject matter. While most of it is traditional media, I also found a gorgeous mural of a giraffe mural from Utrecht in the Netherlands. Posts are predominantly visual and shows a staggering variety of styles. It's a great Facebook group for discovering animal themed art, whether old or new.

Cat Memes

Any cat owner will recognize the wonderfully ironic contradiction that is inherent in their pets. They are adorable, yet aloof. Intelligent, and silly. Dignified, yet playful. Independent, yet uncannily symbiotic with their humans. Any cat owner will find many of the cat memes instantly recognizable, as it expresses both the love and exasperation that many feel towards their cats. Cuteness overload may happen, especially when there are kittens involved. Many memes will make you laugh out loud or chuckle quietly. This Facebook group for cat lovers is the perfect cure for a rainy day and one of the best things to add to your news feed.

Forever Fall and Halloween

 If you love the smell of pumpkin spice and the sound of anything that goes bang or boo in the dark, then this Facebook Group is most definitely for you. There are many posts about horror movies to get you into the mood for Halloween. I also enjoyed several spooky art interpretations. Get ideas for porch decorations, costume design and other assorted accessories. Pay a virtual visit to some spooky places. For anyone who believes that Halloween should not be limited to one day or even one season.

Rome and Constantinople (New Rome). The Roman (and Byzantine) Empire

How often do you think of the Roman Empire? Daily? Weekly? Whatever your answer to this TikTok trending question, the Roman Empire remains relevant for the role it played in shaping the world we live in. Our current calendar is based on one devised by Julius Caesar and our legal system contains numerous concepts that have their roots in Rome. For a daily dose of Roman history posts, you could do worse than including this Facebook group in your social media news-feed. What's interesting is that it focuses not only on ancient city of Rome, but also the later divided kingdom, and the eastern empire that was centered in Constantinople. You will see glorious Byzantine churches, ruins in Tunisia, coins, forts and much, much more. There are also numerous posts that analyze the legacy of important figures from Rome and the Byzantium.

A Gathering of Crones... Reoccupying archetypes of the mature feminine

As a mature woman well on the way to cronedom (or is it cronehood?), I am already enthralled by this Facebook group's name. So naturally, I had to investigate. And I was not disappointed. One of the very first posts, contained a ode to the wonders of feminine solidarity. The community celebrates creativity and wisdom. It's a wonderful, wonderful space. Recognize those little flints of yourself in snapshots, cats, woods and hedges, quotes, artwork and so much more that puts women of a certain age at the heart of the universe, where they undoubtedly belong. Discover the magic that hides inside everyday things. By random chance, my visit coincided with the Wednesday Crones Bazaar Day event.
