author
A Church of England clergyman and theologian, he wrote a clear, practical guide to the Book of Common Prayer for readers who wanted to understand the meaning behind Anglican worship. His best-known surviving work, first published in 1901, focuses on the daily offices, the litany, and the shape of public prayer.

by Percival Jackson
Percival Jackson is a little-documented religious writer whose name is now chiefly associated with The Prayer Book Explained. Contemporary and later catalog records identify the book as the work of Rev. Percival Jackson, M.A., of Jesus College, Cambridge, and editions and listings consistently place its original publication in 1901.
In that book, Jackson set out to explain the structure and purpose of the Book of Common Prayer in a straightforward way. Rather than treating worship as mere routine, he wrote as someone deeply invested in the meaning of Anglican liturgy and in helping ordinary readers follow its services with understanding.
Because reliable biographical information about him is scarce in the sources I found, it is safest to remember him through the character of his writing: careful, devotional, and aimed at making established forms of worship easier to appreciate. His work has remained available through reprints and digital archives, which suggests a lasting niche interest among readers of Anglican history and practice.
