Early proponents included Richard Lassels in his 1670 book on a Voyage to Italy. These writings now serve a role in scholarship about the history of Rome, present and past. Among the pre-modern guides or itineraries to Rome, are: Mirabilia Urbis Romae (1140s), Anonymous. Descriptio urbis Romae (ca.1433), Leon Battista Alberti Roma Instaurata, (written 1444 printed 1481), Flavio Biondo Studio di Pittura scoltura et architettura nelle Chiese di Roma (1674), Abate Filippo Titi. Antiquae Notitia or the antiquities of Rome in two parts. (1713), Basil Kennett. Indice istorico del gran prospetto di Roma: ovvero Itinerario Istruttivo. (1765) Giuseppe Vasi.
