An archaic or variant spelling of scroll, a rolled document or parchment.
From Old French escroue, a variant of escrowe, meaning a strip of parchment or rolled document, influenced by the verb escroller (to roll).
This medieval spelling variant shows how English was still borrowing directly from French and hadn't settled on standard spellings—'escrol' vs 'scroll' is like the texting abbreviations that might or might not survive into the dictionary.
