Inventory of merchant living in a house looking onto the church of Santa Anna (ff.2v-23). Costa also appears to have been a jurist at some time (IAHPB, 2001, p.423). The inventory comprises the contents of Costa's house, as well as that of a tower located close to the church of Santa Maria del Pi. There are no musical instruments mentioned, but it is clear that Costa was very wealthy, with large amounts of silver, books, an expensive llit de camp, and tapestries. Also included in the tower are documents for extensive land holdings outside Barcelona.
