According to Basque traditions, Olentzero comes to town late at night on 24 December to drop off presents for children.
Other theories of derivation exist but are not generally accepted:[1] In parts of Navarre this holiday is called xubilaro or subilaro from subil, the word for a Yule log plus the suffix -zaro.
[3] Other versions of the Olentzeroren kondaira, or "history of Olentzero", tell that as a new born he was abandoned in the woods and was found by a fairy who gave him the name Olentzero, bestowed gifts of strength and kindness on him and handed him to an older childless couple living alone in the woods.
Other variations of the legend, customs and the character include: Around 1952, in Francoist Spain, a group called Irrintzi Elkartea from Zarautz began to revive the Olentzero traditions.
In the modern version, Olentzero is depicted as a lovable character, widely attributed to being overweight, having a huge appetite and thirst.
On Christmas Eve, groups of people or children carry effigies of Olentzero around on a chair through the streets, singing Olentzero carols and collecting food or sweets (not unlike the American trick or treat) and the traditions surrounding the holiday of Santa Ageda in the Basque Country where oles egitea "asking for alms" is practised.
Variation is still common, both regionally and culturally depending on whether the pagan or Christian aspects of Olentzaro are being emphasised.
Since 1994,[5] he has started to be accompanied by Mari Domingi,[6] a character previously mentioned in a Basque Christmas carol.
