Flags of the imperial era
Orts mentions the flag of Valencia, trumpet-shaped and with four stripes (or bars in its vertical position).
In the altarpiece of the Chapter Room of Alzira appears a red flag with seven yellow stripes.
The most common flag is the swallowtailed with four stripes used in all the territories of the crown that we have already seen before. A variation appears in a painting by Lluis Mata.
Calvo and Grávalos show in Flags of Spain a supposed Infantry flag that contains five red stripes in yellow field, and over all the cross of Burgundy. It is taken according to the source from the table by Giambanista Castello "The Battle of San Quintin" that exists in the monastery of El Escorial.
In the Battle of Lepanto were present Catalan ships. A Venetian painting shows a yellow square flag with three red stripes.
