This paper presents the linguopoetic analysis of the Latin panegyric "Iter Laureatum" by Hryhorii Vyshnovskyi, dedicated to Josaf Krokovskyi, the former rector of Kyiv-Mohyla Academy. The panegyric is analyzed within the historical and cultural context of that time. The purpose of this study is to give the idea of the structure, poetic means and individual author's performance of the genre in Latin language. The relationship between Ukrainian baroque poetry and antiquity is defined in precedent texts. Precedent texts actualize well-known cultural phenomena, thereby creating the effect of recognition. It is proved that the transfer of the narrative to the mythological plane creates the effect of historicity and legendary nature of the event or personality, which benefits panegyric pathos. The article focuses on lexical poetic means (analysis of poetic interpretation of mythological names) and stylistic means (the amplification, anaphor, use of metaphors and comparisons). The mythological names are classified according to the main thematic groups: geographic names, representing the ancient and medieval realities (Regna Mauri, Regna Lydiae, regna Arabum, Canopus, Thracia, Rhodopa, Troja), personal names of mythological characters (Apollo, Melpomene, Polyhymnia, Thalia, Siren, Echo, Hercules), words of musical art (chorda, carmen, lyra, chorus, nablium), martial arts (Mars, Scipio, trophaeum). The following metaphors were defined for description of patron's dignity: "majorum decus"; "pater Rossiadum"; "patronus pupillae sortis"; "victor cordis"; "princeps pectoris". We direct attention to the realization of author's narrative strategy of the will-expression, which is to exalt the patron's generosity and express the affection and loyalty towards him. It is discussed the poet's intention to cross the time barriers and transfer the mythological realities to the Ukrainian ground (Borysthenes, Siren Kioviensis).
