Circles around the Sun

"Look, the children are playing ball on the lawn, with Sam," said Alix.
Their figures, in a wide circle, were tiny far away, like another sundial, Matt thought, only these figures moved. Then Alix said it.
"They're like a sundial too."
"Games played in circles are games of the sun," said Theo.
"Ring of roses," said Matt. "The Rose Round."
He could see the Rose Round from here, away in its corner by the woods, and suddenly remembered looking through the telescope at it.
"We all go round the sun," said Alix.
"And the sun is the shadow of God," said Theo. "Lux Umbra Dei."
