Ars Notoria, Chapter 20 summary
Chapter 20 of 66 · 7 min to read the chapter
In Chapter 20, prayers ask God to strengthen memory, cleanse conscience, and grant sacred knowledge, while explanations attribute their powers and secrets to Solomon and angels. The instructions connect these requests with lunar phases, moral purity, study, and an ordered sequence of prayer parts separated by a brief pause.
What happens
- An opening prayer asks divine wisdom, power, and love to restore understanding, memory, and conscience.
- Explanations connect the prayers with Solomon, angelic revelation, protection from danger, and knowledge of theology.
- Instructions assign recitation counts to lunar phases and require purity, morning prayer, and preliminary study when needed.
- A prayer attributed to an angelic delivery receives a warning against saying it more than once.
- Further instructions divide prayer into parts and request lasting understanding of sacred writings.
- The second and third parts receive accompanying petitions, with a half-hour pause before the third and a fourth part afterward.
