1. The Romans occupied Britain for four centuries (43 - 416 A.D.) and built a national network of straight and direct highways for moving troops and military supplies. "Directness" means the highway is very straight. "Uneventful" means there are no bends.
2. The word Lucifer is taken from Latin, which means "the morning star", or, "light-bringing". Lucifer before his fall from grace can be magnificent. William Blake's drawings of Lucifer show some beautiful muscular nude bodies. Other drawings through the centuries have shown Lucifer to be a tall, good-looking, sexy man. Lucifer is also known as "son of the dawn", hence Prince of the Morning.
