Fishermen or seafarers had their initials engraved in the creole so that they could be more easily identified if a sailor died abroad (shipwreck). At the same time, the value of the golden creole, which the parish of the site was allowed to keep, guaranteed a Christian burial. Carpenters and other builders still wear a creole in their left ear as a guild symbol.
