Facing onto Vicolo dei Balconi, the external façade and the entrance are embellished by First Style decoration, partially displayed in the Antiquarium, in the form of a stucco imitation of a wall with rows of square stone blocks. The House takes its name from the elegant floor mosaic (emblemata) discovered in its left wing, with a rare depiction of the catasterism of the mythical hero Orion, that is the transformation of the hunter into one of the most fascinating celestial constellations, by will of Zeus. The scene is connected, by virtue of a similar composition, to a second incomplete mosaic present in the diurnal cubiculum, which also depicts Orion as the hunter of a monster and beasts, aided by a butterfly. Both works highlight the high cultural level of the owners.

The dwelling, previously discovered during the excavations of the 19th century, possesses a spacious central atrium, surrounded by rooms decorated in the First Style with detailed floor mosaics. Precisely because of these decorative associations, the house reveals a rather retro style for its era, with stucco frames and panels of the most ancient Pompeian style in place of more modern pictorial cycles of the Fourth Style.

Date of excavation: 2018-2020.
