Spanish to English Art/Literary Art, Arts & Crafts, Painting Francisco de Goya

This is from a description of a painting from a series by Goya called 'La captura del bandido “Maragato” por fray Pedro de Zaldivia'.

I am wondering which of Hercules' exploits the above phrase refers to, if any, since during his labours he vanquished many beasts. Does anyone know/have an opinion on whether this is likely to be referring to any one set of animals in particular from the labours, or perhaps one of the incidents that happened along the way? Or is this perhaps some general vagueness on the part of the author? Is anyone familiar with this as some traditional scene with a general common title which might be depicted in art that the author could be referencing which shows Heracles/Hercules beating wild animals, perhaps?

Your opinions on the matter would be gratefully received, since I am not entirely sure what the author is referring to here, and since Hercules used his club quite a lot, I am unsure which occasion they might be thinking of.
More context below. UK Eng please. Thanks in advance.


El cuarto episodio del ciclo marca el comienzo del declive del “Maragato”. Cuando el bandido trata de alcanzar las escopetas del caballo, fray Pedro da la vuelta al fusil y se dispone a golpear a su enemigo con la culata. El bandido, caído al suelo, mira asustado a fray Pedro, cuyo rostro pintado por Goya refleja la duda y el conflicto interior de quien no está del todo convencido de sus actos. Finalmente, el monje reflexionó y decidió no golpear al malhechor sino al caballo, que salió espantado.
Se ha señalado que la postura del fraile está inspirada en las figuras clásicas de ***Hércules golpeando a las fieras***. Este es el momento en que mejor se combinan la humildad que fray Pedro mostró al llegar a la casa tomada por el bandido, y la ira de Dios que llevaba dentro, de la que se sirvió para capturarle, tal y como se pude leer en el folletín.
