Special flags (c. 14th century)
In the "Llibre de les coronacions dels reis d'Aragó" (Book of the coronations of the Kings of Aragon) appears a vertical rectangular flag, with two red stripes and one central yellow (a threeband in vertical).
The flag assigned to the Kingdom by the Libro del Conoscimiento de todos los Reynos (Book of the Knowledge of all the Kingdoms) has the shape of an horizontal shield, with four red bars on yellow. This same flag is assigned also to Sardinia.
A flag of uncertain use appears in an altarpiece in the Church of Cardona: it is vertical yellow with three cutted stripes.
Other strange flag appears in the "Corporals" Altarpiece, yellow with four red cutted bars, the lower of a smaller size to compensate the lack of the lower angle of the fly of the yellow zone.
And finally a flag drawn by a notary of that time, in a way more or less trumpet-shaped, with eight stripes, four red and four yellow.
