The Lábaro is an ancient military standard of the
Cantabri people of pre-Roman
Spain. It consists of a purple cloth on which there is what would be called in heraldry a "
saltire voided throughout" made up of curved lines, with knobs at the end of each line.
Etymologically, the word comes from (p)lab- which means to speak in a number of
Celtic languages, many of which have derivatives. For example, in
Welsh llafar means "speech", "language", "voice". Ancient
Cornish and
Breton have lavar, "word", and ancient
Irish has labrad: "language", "speech". In
Latin, the lábaro became known as the Cantabrian Labarum.
