David

We just learned about the person from the Bible named Saul.

Another person from the Bible was David.

After Saul had made God angry, Samuel went out to pick a new King for Israel.
Samuel went to the farm of a man named Jesse, and God picked the youngest of his eight sons, a boy named David to be the new king.

David went to work for King Saul, and went Saul was not feeling well he would play his harp, also called a lyre, to help him feel better.

One day the people of Israel were in a battle with the Philistine people, who had a giant warrior named Goliath.
Everyone was afraid to fight Goliath, except David, because David had faith that God would help him beat Goliath.
They tried to give him armor, but he said that God would protect him.
David took a rock and used his slingshot to throw it at Goliath and killed him, and won the battle for God.

Later on David was the king, and he won many battles for God's people.
He also wrote many songs which are in the book of Psalms.

One day David was up on the roof of his palace, and he looked over and saw a woman bathing.
He knew that he should not be looking at her, but instead of looking away he told his servants to go get the woman and bring her to him.
She was married to someone else, so this was a very bad thing that David did.
God was very angry with David for taking someone else's wife, since he was king and had so many wonderful things already.

David ran away and begged God for forgiveness, and that made God happy, so he let David's son Solomon become king after David died.

Portals at Chartres Cathedral

We just learned about the Pórtico da Gloria.

After the Romanesque time of sculptures, a new type of sculpture came around, called Gothic.
This was a lot like the Romanesque, but the statues and buildings were taller, had more windows, and were more pointed to the sky, like they were celebrating heaven.

One type of Gothic sculpture was the large sculptures above doorways, called portals at the Chartres Cahtedral.
There were three different entrances to the Cathedral, and each of them had three arch ways full of sculptures.
From the tympanum over the doorway, to the pillars holding the doorway up, there are hundreds of sculptures.

They all tell many stories from the Bible, from King Solomon, to John the Baptist, to Mary the mother of Jesus.

Darwin's Frog

We just learned about the Common Midwife Toad.

Another type of frog is Darwin's Frog that lives in South America.
It is called Darwin's frog because it was discovered by Charles Darwin in 1841.

The white and brown on the frog makes it look like a dead leaf laying on the ground when they are sitting still trying to hide.

One very interesting thing about this type of frog is that the male frogs carries the eggs inside their mouth until they are ready to hatch.
