Saint Jerome in His Study is an oil painting on panel no larger than an oversized postcard attributed to the workshop of the early Netherlandish painter Jan van Eyck and is currently in the collection of the Detroit Institute of Arts.

He is surrounded by objects exemplyfying late medieval intellectual life and accompanied by the pet lion that is his common attribute.

[2] Since the date on the painting is subsequent to Jan van Eyck's death (June 1441), it is likely that the work, left unfinished, had been completed by members of his workshop, or his brother Lambert.

He wears a cardinal's dress and hat, and is reading a book, in a small study clogged with numerous objects showing his erudition and interests.

Objects on the desk and the shelves include an hourglass, a pounce pot, a ruler, an astrolabe, numerous books and writing instruments, all suitable for the idealized Renaissance man.
