Liber Regalis (Royal Book — Coronation Ordinal)
The Liber Regalis is the coronation ordinal held at Westminster Abbey (MS 38) that provided the order of service for every English coronation from Richard II through Elizabeth I. For James I's coronation in 1603, it was translated into English for the first time, and all subsequent Stuart and Windsor coronation liturgies descend directly from that adaptation. The anointing, investiture, and crowning prayers recited over every Stuart and Windsor monarch derive ultimately from this single manuscript. It is now on permanent display in the Queen's Diamond Jubilee Galleries at Westminster Abbey, and the coronation of Charles III in 2023 traces its liturgical form through this medieval book.
