Prvi je cilj ovoga rada razjasniti osnovni integralni sustav prometnih putova gledatelja unutar Amfiteatra u Puli, a u tome kontekstu podjelu gledališta na sektore (maeniane), koje su smjeli koristiti različiti stališi gledatelja u odnosu na njihov priznati položaj u društvu. U tom okviru središnja su tema ovoga članka četiri osobita stubišna tornja sa summa cavea in ligneis, s inkorporiranim bačvastim cisternama, s dvostrukim ukrižanim drvenim stubištima i tri palube, a koji do ovoga rada nisu nikada cjelovito i razložno proučeni, a još manje prikladno grafički prezentirani u izvornome stanju u kakvom su bili kada su nastali sredinom 1. stoljeća pr.Kr. The primary goal of this study is to analyze the basic integral system of passageways for spectators of the Amphitheatre in Pula as well as the division of the auditorium into several seating sections reserved for different classes of citizens according to their social rank. This paper focuses on four staircase towers with summa cavea in ligneis with incorporated barrel-like cisterns with double crossed wooden staircases and three decks. They have neither been systematically explored so far nor graphically represented in order to show what they might have looked like in the period of their construction (mid-1st century B.C.).
