About this work
Subject & Meaning
Accompanied by the martyrs Firmus and Rusticus, Grata displays the severed head of Alexander of Bergamo to her pagan father.
The painting illustrates the legend of Saint Grata, presented as an ancestor of the Crotta family. Accompanied by the martyrs Firmus and Rusticus, Grata displays the severed head of Alexander of Bergamo to her pagan father. The scene captures a specific miracle where flowers bloom from the wound instead of blood, a sight that convinces her father to convert to Christianity and spread the faith in Bergamo.
Beyond its religious narrative, the work functions as a tool for social advancement. The Crotta family, originally from Bergamo but residing in Venice, commissioned the piece to elevate their status within Venetian society by emphasizing their noble lineage and connection to these holy figures.

Context
The Patron Saints of the Crotta Family is attributed in most sources to Giovanni Battista Tiepolo, though one reference assigns it to his son Giovanni Domenico Tiepolo, reflecting ongoing uncertainty about authorship within the Tiepolo workshop tradition. The work was produced in 1750 as an oil painting, and its subject, the legend of St. Grata and the martyrs Firmus and Rusticus presenting the head of Alexander of Bergamo, was chosen by the Crotta family, Bergamese transplants to Venice, to bolster their Venetian social standing. The painting is now held in the Städel Museum in Frankfurt, where it is classified as a religious history painting.
The commission exemplifies how eighteenth-century Venetian families used commissions of sacred narratives tied to ancestral or regional legends as instruments of social positioning, a practice well documented in Tiepolo patronage studies.
