The figure of Saint Hyacinth arouses constant interest. This includes the Saint's life and works, but also his ‘fate’ after his death: his cult, his relics, his presence in popular piety and in art. This article deals with a subject at the intersection of cult and art; more specifically, the author addresses the second tombstone of Saint Hyacinth in the context of a recent discovery in the archives of the Dicastery for the Causes of Saints. The design of tombstone of 1589 allows us to supplement our previous knowledge of the Krakow monument built in 1583. It has survived for less than 50 years, yet it continues to arouse the interest of scholars because, in their unanimous opinion, it was an outstanding work of Polish artists with no parallel in Poland. The discovered drawing, from the time of the tombstone's existence, does not close the research on its final appearance, however, it allows to verify the hitherto attempts of its visual reconstruction and constitutes an important step on the way to a better understanding of this ‘pearl of the Polish Renaissance’, which was the second tombstone of Saint Hyacinth.
