The Margaret Codex
The Margaret Codex is a copy of a lost earlier book. The legend was originally denoted in Latin in the 14th century, and soon was translated to Hungarian. The document was copied in 1510 by the famous early 16th century Hungarian nun, Lea Ráskay. Ráskay is also valued by posterity for saving a number of other Old Hungarian works.
She did not simply copy the book, but also applied her own orthography, and added several glosses.
