I frutti caduti nel fondo e le bestie al pascolo. Un'analisi giurisprudenziale sulle azioni esperibili

The research faces a cross examination of two Ulpian's passages – D. 19.5.14.3 (41 ad Sabinum) e D. 10.4.9.1 (24 ad edictum) – concerning similar specific cases that pose the same theme of identifyng the actions that can be carried against the neighbor by the owner of the fruits fallen on the plot of other, and eaten by the cattle grazing. Different solutions are proposed, attributable respectively to Aristo (that of D. 19.5.14.3) and to Pomponius (that of D.10.4.9.1), at first sight dissimilar, but complementary when better observed. Actually, a line of reasoning that recomposes the opinions of the two jurists could be found, as the undoubted intellectual link between them also suggests. Ulpian might have gained knowledge of both opinions from Pomponius's Ad edictum, set out in a continuouos discourse about the formula of the actio ad exhibendum; and could then have dismantled the fragment by using Ariston's opinion about theft in the Ad Sabinum, and Pomponius's opinion about the commentary on the actio ad exhibendum in the Ad edictum, showing full agreement and going even further.

本研究针对乌尔比安（Ulpian）的两处文献片段展开交叉考证——即《学说汇纂》（Digest）D.19.5.14.3（出自《论萨宾》第41卷）与D.10.4.9.1（出自《论告示》第24卷）。二者涉及相似的具体个案，核心主题均为：当果实掉落至他人土地并被放牧牲畜啃食后，果实所有权人可对邻人提起何种诉讼。
研究分别提出了两种不同的解决方案，前者可归属于阿里斯托（Aristo）的观点（对应D.19.5.14.3），后者则属于蓬波尼乌斯（Pomponius）的观点（对应D.10.4.9.1）。初看之下二者观点相异，但经深入研读后会发现二者实则互补。
事实上，正如二者之间确凿无疑的学术关联所暗示的那样，我们可以找到一条能够整合这两位法学家观点的论证路径。乌尔比安或许是从蓬波尼乌斯的《论告示》中获悉这两种观点的——该著作曾以连贯的论述阐释了出示之诉（actio ad exhibendum）的程式；随后他或许借助阿里斯托在《论萨宾》中关于盗窃的观点，以及蓬波尼乌斯在《论告示》中针对出示之诉的评注观点，对该文献片段进行拆解，既展现出与二者的完全契合，甚至还进一步拓展了相关论述。
