Gaspar Van Wittel painted two oval views of Tivoli in 1691, now in the Rospigliosi collection in Rome. Further drawings of Tivoli are illustrated in W. Vitzthum, Gaspar Van Wittel, exhib. cat., Palazzo De Vio, Gaeta, 1980, no. 47-7. The figure on the verso is comparable with that on a drawing in the Palazzo Reale, Vitzthum, op. cit., no. 16, illustrated.
