Brevi note su natura ed effetti giuridici dell'alluvione in una lex di Teodosio II del 440

The essay deals with acquire of ownership by alluvial activity in Roman Law, with particular reference to a constitution issued by Theodosius II in 440, happily known in its reasonably original extension (Nov.Th.20, sum up by Justinian’s code commission in 534 [C.7.41.3]). The topics herein studied are natural description of ‘adluvio’ in Roman law sources (quite complex on this issue), juridical nature of ‘adluvio’ (increase of land that borders with a river), legal effects of ‘adluvio’ (acquisition of alluvial increase by the land owner rather as a juridical acquire ‘iure gentium’ than a mere physical increase of land with no legal matters related to it), condition of lands where alluvial acquires could take place. A significant connection with other fluvial events that gained relevance in Roman law (known in legal tradition as ‘avulsio’, ‘alveus derelictus’, ‘insula in flumine nata’) is always set forth in the article.
