Les événements importants liés à la vie du Bouddha Gautama ne sont pas représentés de manière cohérente dans les anciennes écoles d'art d'Asie du Sud et du Sud-Est, et son éveil représenté sur la bannière de l'ancienne collection Adhémard Leclère au Musée des Beaux-arts et de la dentelle d'Alençon, suscite la controverse. Cette communication démontre que cette controverse est due à la confusion et à l'irrégularité de la façon dont les événements liés à la vie du Bouddha sont relatés dans les textes sacrés.
