Along with wills, prenuptial agreements and contracts, the post-mortem inventory was one of the most commonly drawn up official documents. It is of great importance for history and material culture. It allows us to reconstruct a person's wealth and is also a source of information for historians of art, intellectual culture or clothing. In the case of the posthumous inventory of Count Canon Michał Ankwicz, we can also see that it can significantly supplement the information on his biography. Michał Ankwicz was the son of Hieronim and Elżbieta, née Czerne, and the brother of Wawrzyniec, Stanis³aw and Andrzej. He was born in 1722 in Red Ruthenia. He entered the Jesuit Order in Krakow in 1736. In the years 1747-1749 he completed his theological studies in Rome, after which he worked on missions in the province of Sandomierz and then became the superior of the seminary in Sandomierz. After the dissolution of the Jesuit order, he was parish priest in Modlnica and Rachwałowice. In 1778, together with his family, he received the title of count from the Austrian court. Towards the end of his life he lived in Cracow, at Kanonicza Street, where he died on 14 April 1786. His post-mortem inventory, consisting of 6 pages, was drawn up on 19 April 1786. The inventory in question comes from the so-called collection of Jan Wincenty Smoniewski, kept in the Scientific Library of the PAU and PAN in Cracow, mps 430.
