Na temelju stilsko-komparativne analize opovrgava se atribucija poliptiha iz crkve sv. Ante Opata na Koločepu dubrovačkomu gotičkom slikaru Ivanu Ugrinoviću kao i njegova datacija u 1434. godinu. Ukazuje se na mogućnost da bi koločepski poliptih mogao biti djelo zasada nepoznatog slikara oblikovanog na slikarstvu Paola i Lorenza Veneziana, djelatnog u drugoj polovini XIV. stoljeća, a najvjerojatnije između druge trećine i kraja tog stoljeća.In this article author discusses attribution problem regarding the polyptych from the church of St. Anthony Abbot on the island of Koločep. Until recently this piece of art was attributed to Ivan Ugrinović, gothic painter from Dubrovnik. Moreover, literature maintained that this polyptych was painted in 1434. On the basis of thorough stylistic and comparative analysis, author disputes this and suggests that this polyptych could be work of unknown artist from Venice, or a painter who was infl uenced by Paolo and Lorenzo Veneziano. Moreover, author proposes that this painter was active in the second half ofthe fourteenth century and that the polyptych was probably painted in the last quarter of the same century. Furthermore, author examines published sources about Ivan Ugrinović, and provides a complete transcription of an unpublished document that is presently kept in the State Archives in Dubrovnik
