Rising:

Orion will fashion alert minds and agile bodies, souls prompt to respond to duty's call, and hearts which press on with unflagging energy in spite of every trial. A son of Orion's will be worth a multitude and will seem to dwell in every quarter of the city; flying from door to door with the one word of morning greeting, he will enjoy the friendship of all. (Manilus).
