художнику

"To the artist" (dative case of "художник").

Here, 'художнику' is the dative case of 'художник,' used to indicate the indirect object of the verb 'подарил' (gave) — 'to whom' the book is given.

Я подарил книгу художнику.

I gave a book to the artist.

In this sentence, 'художнику' is in the dative case, used to express gratitude or direction towards an entity for an action or object, underlined by the prepositional phrase 'за прекрасный портрет' (for the beautiful portrait).

Спасибо художнику за прекрасный портрет.

Thank you to the artist for the beautiful portrait.

Here, 'художнику' is again in the dative case, showing respect or acknowledgment directed toward 'художнику' (the artist in question).

Надо отдать должное художнику за его мастерство.

Credit must be given to the artist for his skill.
