This book, together with its counterpart Lord of the World, is an early venture into the "speculative" genre of fiction. Written in 1911, it could be considered early science fiction with its descriptions of future technology, but it is really much more a religious and philosophical exploration of the effects of belief systems on society.

6 volume set, reference work for adults.

Living books instead of textbooks for teaching. "Narration" or retelling what one has read, rather than fill-in-the-blanks workbooks. Short lessons of 10 to 30 minutes, leaving time for handicrafts and exploration in the afternoon. Plenty of time outside in God's creation, learning to draw and identify plants and animals. If you are using any of these ideas in your homeschool, you may owe a debt of gratitude to Charlotte Mason.

Citadel of God is set in Italy of the early 6th century. The Roman Empire is decaying. An Ostrogoth king, Theodoric, is marching in triumph to occupy Italy. A young boy, ward of the respected Roman scholar Boethius, rushes in to stab the barbarian conquerer with a stylus in defense of Old Rome and is rescued from death by a young scholar from Nursia who is called Benedictus.

Miquon Math is a series of 6 math workbooks designed to be used in 1st through 3rd grade. They are named by color and not by grade level, so that an older child can use them without feeling they are "remedial". The workbooks are designed to be used with Cuisenaire Rods. I have had the books for a couple of years but have only started using them this year as a supplement for my 3rd and 4th graders. I hesitated using them before because they have an unusual format -- the pages don't necessarily have to be done in order, and are grouped by topic rather than in sequential chapters.
