“Il Caffè” by Alessandro and Pietro Verri was modelled on Addison’s paper and was meant to serve the same purposes, so you can note various differences and similarities between them.
The Spectator was addressed to the middle classes, which had recently gained social importance. In the first number of Il Caffè where Pietro Verri declares that it is addressed to the citizens in general.
Verri brothers wanted to talk about “various things, unpublished things, things made by different authors, all things direct to the public utility”, while Addison meant to give an account of the several people that were engaged in that work.
The aim of the Italian paper is to spread some useful knowledge among the people of Milan by entertaining them, while Addison designed his paper to gratify the curiosity to know if it’s true that a reader seldom peruses a Book with pleasure till he knows the main particulars of the like nature and to comment upon all the customs of the society of the time.
The style employed in the Spectator is clear, simple and lively just like the one in Il Caffè.
The title of Addison’s paper derived from Mr Spectator, who was the imaginary man answering to the letters of its following writers; instead Pietro Verri refered to a shop where was produced coffee and where many intellectuals met to talk to each other.
The Spectator was published daily except for Sunday, from March 1711 to December 1712, with a total of 555 issues, while the author Il Caffè declared that the paper would be published every ten days, until the public would stop reading it.
