The big house is the result of two houses being merged in the 1st century BC, one with its entrance on via Stabiana and the other from the Lupanare alley. The decorations of the entire property were being radically renovated at the time of the eruption, according to the principles of the time.

The exedra was one of the parts already completed, where the guests feasted on couches around a fine floor made of marble slabs and surrounded by beautiful frescoes with mythological subjects inspired by the Trojan War, one of which is exhibited at the National Archaeological Museum of Naples. The last owner of the house, Publius Vedius Siricus, was identified thanks to the discovery of a bronze seal bearing his name. Sirico belonged to the political and trade class of Pompeii and met with his supporters on a daily basis in his home, welcoming them with the auspicious inscription SALVE LUCRU, Welcome, money! that could be read on the floor of the entrance.

Date of excavation: 1851-1852; 1857-1859; 1862; 1872-1873.
