update 12/29/2021 beautiful beguiling books with the four minor mathematical arts of the ancient seven liberal arts. Beautiful and fascinating but a little untrustworthy like ancient wisdom. I don't blame them they did their best. Enjoyable in the ingenuity of the ancients in seeing patterns in number, geometry, music, and astronomy. Sometimes they were fooled but found some nice gems on the way.
