What are Saint Maximus's notions of the 'logoi' and the 'Tropos/tropoi'?

It confuses me a bit as to what they actually are? It seems that every individuated object has its own Logoi, while the Logoi is not in the thing itself. Is it some sort of ideal of the object, with which Christ, being God, is the complete exemplary? Is the Tropos then the actuation of this, with the Tropoi being the Will's conformity to this.

What is also the Logoi in relation to contemplation? The Intellect, in contemplating a particular object, enlightens the object to see its universal. Is the contemplation of the Logoi like the opposite, where we strip away the universal features and contemplate the Grace that individuates the Substance. It confuses me, and I would like to know what people think.
