Astronomy lesson 1 - The ancient myth makers

When the hundred spirits and the wind and rain became calendrically incorrect and disordered, Gong Gong made the sun and the moon take turns working and resting. Thus we have the divisions of late night and morning, afternoon and evening.

The Astronomy classroom is sparsely furnished. Wooden desks are spread out in even rows. At the front stands a larger desk, with stacks of astronomical encyclopaedias and journals on it.

In what was perhaps an effort to make the room appear more inviting, some of the stone walls have been covered with star charts - however, the real view is offered by the large windows onto the grounds. From the Tower, you can see the lake glittering in the summer's afternoon sun, and behind it, the ominous dark green mass of the Forbidden Forest. Through a different window, the empty stands of the Quidditch Pitch are visible, and, off to one side, the hut of Professor Lawson, the Care of Magical Creatures. Two of the windows have been opened, sending a warm breeze through the room.

Professor Antares is already present. He is fiddling with an ancient-looking projector - a skilful wizarding artificer, long ago, designed it to function within the magical environment of Hogwarts, but the professor, more used to Muggle technology, is still learning how to operate it. Once enlightenment on this score has been achieved to the professor's satisfaction, class will commence.

OOC: The lesson will start in about 30 minutes, I'd say. Please keep chatting down to acceptable levels.
