Guess who has a new Call of Cthulhu game out today?! An Ominous Herald is a murder-mystery set in ancient Rome. Think Knives Out at the Villa of Hadrian. If you want to fight the Cthulhu Mythos wearing a toga and wielding a trident, this one's for you. legacy.drivethrurpg.com/product/5840...
Cover of An Ominous Herald TTRPG by Kat Clay. It features a mysterious ancient Roman woman with a snake around her neck, holding a green drink.

I've written a play, which is premiering in just under a month! My adaptation of Lovecraft's The Rats in the Walls in being performed alongside one of Agatha Christie's one act plays (in which I'm also playing a most unsavoury character). #agathachristie #hplovecraft

Ancient Egyptian hedgehog shaped pottery vessel 🦔❤️ Dated c. 1539-1292 BC. Ashmolean Museum 📷 by me #Archaeology
My photo shows a small, rounded, red polished pottery vessel shaped like a hedgehog. It has a globular body, resting on four short, stubby feet. The clay is a warm reddish-brown with a smooth surface with dark painted details. The hedgehog’s face projects from the front of the vessel with a pointed snout. The almond shaped eyes, and large round ears are painted dark brown/black. Around the face there are short, dark, painted lines suggesting spines. The face is framed on either side of the vessel by curving moulded lines painted dark brown perhaps suggesting the animal’s spines or foliage habitat. A short, cylindrical spout rises from the top of the vessel above the head, serving as an opening for pouring. There is a small handle at the back of the spout not seen in my photo. Dimensions: 8.8 x 7.1 x 7.4 cm (length x width x depth). The vessel is on a glass display shelf at the Ashmolean Museum in Oxford. It was excavated at a cemetery at Abydos and was allocated to the Ashmolean Museum by the Egypt Exploration Fund in 1900.

Hedgehogs had protective associations in ancient Egypt. Because they curl into a spiny ball and prey on snakes and scorpions, they were regarded as apotropaic (protective) animals. Hedgehog-shaped vessels are thought to have held liquids such as oils, perfumes, milk, or water and are frequently found in funerary contexts, suggesting they also had a symbolic role in burials.

Living in the 1760s in London, you may have asked yourself: Why not buy a "Remarkable Tame Panther" that you "may play with it as they may with a Dog"? Or a "SEA-MONSTER"? Or both? What could possibly go wrong with a panther and a sea-monster in your house? I have so many questions.

I pay monthly book tax to keep bookstores alive. What you do is you go into the bookstore, pick out some books that seem interesting, and pay. You do not have to read them! This surefire strategy will keep the book tax collectors off your back.
