Egyptian mythology

Thanks to its magical and divinatory powers, the goddess Isis collected and reconstructed all the pieces of the inert body of Osiris, which Set had hidden in various locations after he killed him.    

In the context of the main belt, the mythology of Isis is compatible with the collection processes that are carried out in nature, as for example the collection of nectar and food of bees and ants, or the construction of nests and burrows of birds and beavers; and whom in agriculture, are equivalent to harvesting.

(42) Isis is related with all kinds of tasks of collection, as for example the collection of signatures in the movie "Erin Brokovich" (2000).
