“The Trinity of Expression” - an artist, a writer, and a composer.
The three ways of conveying images, impressions and emotions, supporting and augmenting each other.
You know, there’s a conspiracy theory that all these different arts were originally one, “the art of imagery”, and anyone skilled in it wielded immense power, since they could manipulate people using the images they created. The theory goes on to claim that the knowledge of it was intentionally split into several arts and thus destroyed a later on.
While I do not believe it to be true, its very existence is quite amusing.
