Index librorum prohibitorum.
Rome: Typographia reverendæ Cameræ apostolicæ, 1758.

The official instrument of Roman Catholic Church censorship beginning in the sixteenth century was the Index of Prohibited Books. Listing authors alphabetically, this edition of 1758 indicates that Galileo’s Dialogo had been prohibited by a decree of August 23, 1634. The revolutionary scientific treatise was removed from the Index in 1824.
