Constellations of Argo, Monoceros and Hydra. More artistic license was taken with Argo and Hydra. Argo Navis is an ancient constellation of the southern hemisphere that has since been broken up into three separate constellations (Carnia, Vela and Puppis). As Madeline's room has a ship, I wanted one in Arianna's room too. I'm also enamored with the story/poem of "Wynken, Blynken, and Nod" which mixes aspects of the stars with the sea. Argo seemed like an excellent constellation to add and made a nice way to interpret a nearby constellation Hydra. Again, I didn't want to add a multi-headed monster to a child's room so an octopus seemed like a good compromise. If she ever asks we planned to tell her the giant octopus is giving the ship a hug.
