 Premise is: Search out the House of Dionysos and the House of the Trident with their simple floor patterns, and the House of Dolphins and the House of Masks for more elaborate examples, including Dionysos riding a panther, on the floor of the House of Masks.
Hypothesis is: The House of Dolphins and the House of Masks are more elaborate than the House of Dionysos and the House of the Trident.
