GIARRIZZO, Domenico Maria (18th century). Prospetto dei saggi politici, ed economici su la pubblica e la privata felicità della Sicilia [WITH:] Saggi politici ed economici su la publica e la privata felicità della Sicilia. Palermo: Solli, 1788. Copies printed on blue paper of these rare works on Sicilian economics, never recorded at auction (RBH), with only three known institutional holdings for the 'Saggi' and six for the 'Prospetto' in Italian public libraries. Giarrizzo, a little-studied intellectual figure, represents an enlightened perspective focused on progress, commercial reform, and public welfare in Sicily. His works examine political and economic matters with the aim of promoting both public and private happiness on the island, offering a meaningful contribution to the discourse on economic and social reform in 18th-century Sicily. 2 volumes, 8vo (215 x 150mm). Engraved vignettes to title-pages, text printed on blue paper (occasional light spotting). Contemporary decorated paper wrappers. (2)
