The author discusses the context and the details of a contract drawn up in Dubrovnik in 1478 between two Korčula masons, Marko Andrijin and Nikola Markov and the Mantuan patrician Valente de Valentis who commissioned a rather large number of chiseled stone items for the architectural decoration of his palace in Mantua. Special attention is given in this text to the systems and units of measurement mentioned in the contract, which indicate the dimensions of the items, the professional terminology used in the contract and the organization of the venture which was demanding because it involved a large commission to be delivered within a short period of time.

U tekstu se raspravlja o kontekstu i pojedinostima ugovora kojim je za svoju palaču u Mantovi tamošnji plemić Valent de Valentis 1478. godine u Dubrovniku od korčulanskih klesara Marka Andrijina i Nikole Markova naručio veću količinu klesanih kamenih elemenata arhitektonske dekoracije. Naročita se pozornost posvećuje sustavu mjera u kojemu su iskazane dimenzije naručene građe, upotrijebljenim klesarsko-graditeljskim terminima i organizaciji posla, zahtjevnog kako zbog količine naručenog tako i kratkoće roka isporuke.
