White saltire in the flag of Gascony
A saltire is a diagonal cross used on flags and in heraldry. For example, the flag of Scotland (named St Andrew's cross) has a white saltire on a blue flag. The Union Jack (the flag of Britain) has two saltires of different colours: a white saltire copied from the flag of Scotland, and a red saltire taken from a flag of Ireland (named St Patrick's cross).
