Augustine of Hippo, on Gen 1:26

“And he said: Let us make man to our image and likeness: and let him have dominion over the fishes of the sea, and the fowls of the air, and the beasts, and the whole earth, and every creeping creature that moveth upon the earth.”

“For God said, "Let us make man in our image and likeness": a little later, however, it is said "And God made man in the image of God." It would certainly not be correct to say "our," because the number is plural, if man were made in the image of one person, whether Father, Son or Holy Spirit. But because he is made in the image of the Trinity, consequently it was said "in our image." Again, lest we choose to believe in three gods in the Trinity, since the same Trinity is one God, he said, "And God made man in his image," as if he were to say "in his [own triune] image."”
