The errebombillos festivity “… dates back to the victorious battle of Lepanto, when celebrated men from Elorrio or elorrianos as they are known, under the command of John of Austria, fought against the Moorish forces…”. Therefore, “… the date on which it is regularly held is in keeping with the tradition, as Lepanto and Our Lady of the Rosary embody historical recollections…”(1).
There are more popular versions that go into more detail, where it is contented that several members of the Amandarro family, when they returned from the battle, fired several rounds when they reached the Kanpazar gate. Passed on by word of mouth from generation to generation, romantic touches have been added and the accounts are a cornerstone for the tradition to survive in the community.
