The tincture red, indicated in seals and engraved figures of escutcheons by parallel vertical lines. Hence, used poetically for a red color or that which is red. (Her.)
His sev'n-fold targe a field of gules did stain
In which two swords he bore; his word,
“Divide and reign.”
Follow thy drum;
With man's blood paint the ground; gules, gules.
