The Argiletum (Latin Argīlētum; Italian: Argileto) was a street in ancient Rome, which crossed the popular district of Suburra up to the Roman Forum, along the route of the current Via Leonina and Via della Madonna dei Monti.

The name of the street could derive from the clay (Latin Argilla) carried by the waters that descended from the surrounding hills and then conveyed into the Cloaca Maxima.

[1][2] The Argiletum was the street of the booksellers and is mentioned by many ancient authors such as Horace, Martial and Seneca, who have also handed down the names of their trusted suppliers.

As it originally passed between the Comitium and the Basilica Pauli, the Argiletum was eventually absorbed by the construction of the Imperial fora from the time of Julius Caesar onwards.

[4] Paths that were found in the Alta Semita and the domus on the Oppian and Caelian hills converged onto the Argiletum, making it a principal node of public space particularly during the Flavian rule.
