A few days ago, I stood in the graveyard of an 1100 year old church, getting damper and damper in the drizzling rain. A woman walked into the graveyard, waved, said hello, and, as we had previously arranged, handed me a paper bag full of human bones. The life of a churchwarden is a strange one...

Happy weekend! 🦛💙 Here’s a wonderful c. 4,000 year-old ancient Egyptian glossy blue hippo decorated with a little bird perched on the stem of a lotus flower. Egyptian Museum Cairo 📷 by me #Archaeology
My photo shows an ancient Egyptian statuette of a standing blue hippopotamus  on display at the Egyptian Museum in Cairo. It is made of Egyptian faience, a ceramic material coated with a bright blue glossy glaze. The hippo is viewed from the side profile with head on the right. It is decorated in black pigment with outlines of lotus plants which grow in the hippos Nile habitat. A little bird is perched on the stem of one lotus flower. Dimensions: Height 11.5 cm, length 21.5 cm.

Excavated by Auguste Mariette in 1860 at the necropolis of Dra’ Abu el-Naga’, western Thebes. Dated Middle Kingdom, 11th Dynasty, c. 2134-1991 BC.

Egyptian faience is a ceramic material made of quartz. Blue hippos are decorated with black pigment outlining depictions of Nile river plants, in particular lotus flowers. In ancient Egypt lotus flowers had religious symbolism; the flowers close at night and reopen with the rising of the sun in the morning, which was associated with regeneration and rebirth. 

Blue faience hippos have been found in Middle Kingdom and Second Intermediate period tombs. It’s thought they were placed there to help the rebirth of the deceased. Associated with the life-giving Nile, regeneration, and Tawaret, the ancient Egyptian goddess of fertility and childbirth.

Hippos were also seen as dangerous to humans so the legs of faience hippos have often been broken off the statuettes found in tombs, perhaps to make sure the hippo could not harm the deceased in the afterlife.

We announced the new native Go FIPS 140-3 mode today! FIPS 140, like it or not, is often a requirement, and I was increasingly sad about large deployments replacing the Go crypto packages with non-memory safe cgo bindings. Go is now one of the easiest and most secure ways to build under FIPS 140.
