The Gaelic Maundeville (Author: John Maundeville)

paragraph 28

And it is with unleavened (?) bread that they perform the sacrament of the Church, because it was the same kind of bread that our Lord had when He made the Maundy for His apostles on Holy Thursday; and 'tis on that day that they make the bread of the whole Church in that way, and dry it in the sun, and keep it for the masses till the end of the year to be given to sick men in lieu of Christ's Body, just as the host is given by us before death.
