The town is all dressed up for the event with his family's yellow and black flag (thanks to a crusader grandfather) displayed everywhere together with sheaves of yellow broom and hundreds of lily flowers studded into hedges along the way.
I attend the mass in Breton at Minihy, for a while in the back of the chapel and then outside in the cemetery, still singing along from the hymn sheet (Breton is easy to follow and generally pronounced as it looks), and watching pilgrims turn up now and then to crawl under the 'tomb' of the saint, an ornate stone table. The best sensations of the occasion - in the simple and emotional faith of St Yves - are most felt here without the great numbers thronging around the cathedral in Tréguier, where the service in French is also taking place.
Walking into the town along the processional way in reverse - Chemin de St Yves, rue de St Yves - I have time for a leisurely coffee while crowds gather to witness the spectacle. Suddenly I realise that just seeing a bunch of lawyers coming out of the south door with their proud burden is not what I want to see most, and it will be hard to do so or to take photos in the scrum of curious onlookers and the faithful following the parade.
I retrace my steps all the way back to Minihy, where a few are waiting at the point by a wayside stone cross where the main ritual of the procession occurs, on a ninety-degree turn down to the chapel.
The crowd grows and seeking a place with a good view and the sun behind me, I'm forced to get up on a very narrow bank where three older people are sitting with their legs dangling. It requires considerable muscle and foot strain to keep perched up there for more than half an hour of anticipation. Finally the first figures appear and a Breton pipe band leads the way, passing in front of the cross and down into Minihy. Behind it an astonishing spectacle, wave on wave of banners and ceremonial crosses stretching as far as I can see.
This is an old ritual, and of more significance that touches me than is usually the case in official ceremonies. The depth of relationship with place is something I understand. Indeed I am currently writing about St Yves and his paths in the Trégor. Almost every day, despite travelling far and wide in his duties as a priest elsewhere and preacher everywhere, Yves Hélory walked back home to the little family manor house where he tended the old and sick and saw that all their needs were provided for. Thirty or forty kilometres was nothing to him in search of home and belonging. The Pardon, despite all the trappings and pompous lawyers, both of which the saint himself would have deplored, still manages to symbolise this simple truth.
