This rare preparatory drawing for Vasi’s comprehensive panorama of Rome published in 1765 is rendered in full scale. As James T. Tice notes, there are some differences  with regard to the finished print. A number of buildings were shifted in the final version, which also included additional picturesque details in the foreground. Although in the drawing the coat of arms flanked by allegorical figures, the inscribed tablet and the Capitoline Wolf are only roughly sketched, details such as the clouds of smoke around Castel Sant’Angelo are minutely depicted.
