Retina

We just learned about the Cornea.

Another part of the eye is the Retina.

Remember that the black pupil in the eye is really just a hole for the light to come in.
The black color of the pupil comes from the inside of the eye, where the light hits the retina.

The retina is in the back of the eye.
Inside the eye it is shaped like a ball, with the pupil as the hole to let light in, and the retina as inside of the ball at the back.

The retina helps take the light that shines on it, and turn it into signals that are sent to the brain so you can understand what you are seeing.

Hoarding

We just learned about the big gated door called the Yett.

Another kind of castle fortification is a Hoarding.

This is a wooden shed that is built on the outside of a stone castle, to help protect archers and defenders of the castle during a battle.

These hoardings are usually not built on the castle until there is a battle.
When they are put up, there are holes in the side of a castle called putlogs or putlocks that they would put logs into, and then build the hoarding on top of that.

Monasticism

We just learned about the Fifty Bibles of Constantine.

Another part of early Christianity is Monasticism, which means talking about monks.

We've learned a lot before about Monks and Nuns.

During the years 300-400 Christianity went from became illegal and people being killed for being a Christian, to being legal in the Roman empire.

Around that same time is when people started going off by themselves to live in caves, or live in buildings together called monasteries or convents.

Monks and Nuns have been around for hundreds of years, but it first started in the 4th century (300 - 400 AD) and when it was made legal people started making places for monks to live, and the monks also started being very important in how people understood the Bible.

Serpent Labret with Articulated Tongue

We just learned about the Olmec Colossal Heads.

Another ancient art from the ancient Americas is the Serpent Labret with Articulated Tongue.

This is a type of jewelry that was worn in someone's pierced lower lip.
The snake would stick out, and the tongue would even move when they moved their head.
In the place now known as Mexico there were people called the Aztecs that would sometimes pierce their lips and wear things in their mouth like that.

It's made of gold, copper and silver, and was made long ago, some time around 1400 AD.

Electric Motor

We just learned about the Bearing.

One type of motor used for a lot of things is an Elecric Motor.

This motor usually has some electric coils wrapped around a metal pole, spinning around inside a tube.

Some electric motors use the tube to force the pole to spin, and others take the energy from the spinning pole and use it to charge up electricity from the tube around it.
