what does the french crest symbolize?

Question

in detail please

Answer 1

I'm assuming you mean the fleur de lis (or lys). I've cribbed the following from the Internet:

The use for ornamental or symbolic purposes of the stylised flower usually called fleur de lis is common to all eras and all civilizations. It is an essentially graphic theme found on Mesopotamian cylinders, Egyptian bas-reliefs, Mycenean potteries, Sassanid textiles, Gaulish coins, Mameluk coins, Indonesian clothes, Japanese emblems and Dogon totems. The many writers who have discussed the topic agree that it has little to do graphically with the lily, but disagree on whether it derives from the iris, the broom, the lotus or the furze, or whether it represents a trident, an arrowhead, a double axe, or even a dove or a pigeon. It is in our opinion a problem of little importance. The essential point is that it is a very stylised figure, probably a flower, that has been used as an ornament or an emblem by almost all civilizations of the old and new worlds.
