There are many tales about the Po river and his slow travel before flowing into the Adriatic sea and shaping the great Po Delta, from the Phaethon myth: ( the tragic race across the sky vault by the unlucky Phaethon, Helio's son, Zeus str the chariot with a lightning bolt and the imprudent charioteer plunged into the river), to the fisherman and ferry man's old stories.
Certainly, one of the most fascinating is the Luigi Salvini’s story, a Slavic language universitary professor born in 1911, after the war, he established in a small island in the middle of the river Po near Papozze, an independent republic with a boundary, passport and where money was printed but the value was only in dreams. This experience was shared with other professors and friends that in this free island-state they were used to spending their summer holidays in the nature, without rules except those of respect and mutual solidarity.
In the Po delta, Luigi Salvini met his passions: his wife, miss Matelda, daughter of the famous lyricist Luigi Catozzo and this pristine landscape, a beauty that he would let  known to others, especially to the many friends across Europe. We are in 1946 the war has just ended and has left destruction, missing and dead, but the liberation brings new energy , It comes out of a long hibernation to "think" in freedom, and Luigi Salvini with this purpose, built the Tamisiana Bosgattia republic , where man and nature are one, So until 1955 this short wild island became a sort of enclave .
Life in the island usually began in July and finished in September . Living in the Tamisiana Bosgattia republic didn’t mean get belly to the sun <em>(lying in the sun or relaxing in the sun)</em>, but to live you had to make do with what you found in the wildlife, which was indeed very generous, especially with hunting and fishing. The day begins at dawn every morning, as the sun starts coming out from the tops of the poplars, the islanders set up the works established the night before. They need to prepare the boat, reorder hooks and lines, examine the engine depending on whether you want to go fishing, explore the river or get to the Adriatic sea.
In the Island there are no buildings, you live in camping-tents, gas provides electric and essential light, no reading, no radio, no news outside this small word, but a happy site is a must, an easy stage for foreign tourists, in dense swarms, from near and far, they rush to visit this community and admire, although envious of, the happy life of its inhabitants ....

There are many tales about the Po river and his its slow travel journey eastwards before <em>(the sentence meanders like the Po - but the subject is tales! and the subject gets lost!)</em> (down to the great Po Delta where it finally flows flowing into the Adriatic sea) and shaping the great Po Delta . Tales like  the Phaethon myth of Helios's son, unlucky Phaeton, and his tragic run-away race across the sky vault by the unlucky Phaethon, Helios's son, - Zeus struck the chariot with a lightning bolt and the imprudent/rash charioteer plunged into the river). Tales like the ancient stories of the fisherman and ferryman old stories.
Certainly/Surely one of the most fascinating is the Luigi Salvini’s <em>(if you have 'the' no possessive is required here, but if you omit 'the', possessive is required)</em> story. Salvini was/is a Slavic language universitary professor born in 1911 who, after the war <em>(which war! World War II - say so to remove any doubt)</em>, he established an independent republic on a small island in the middle of the river Po, near Papozze, an independent republic.<em> (you are isolating the object too far away from its verb with islands of subordinate clauses).</em>  A republic with boundary and passport, and where in which money was printed/which had its own currency , but the value of which was only in a dreams. <em>(you really do construct sentences as long as the Po - but more winding!)</em> This experience was shared with other professors and friends that in who were wont <em>(wont=accustomed)</em> this free island-state they were use to spend their summer holidays on this free island-state, in the nature, without rules, except those of respect and mutual solidarity.

This is not a completed correction as two or three point made in the story need clarification.  I tried not to change any meenings, however, some sentences were completely rewritten as what was there just did not feel right to my native ear.

There are many tales about the Po river and its slow travel before flowing into the Adriatic sea where it shapes the great Po Delta to the fisherman and ferry man, just old stories. One ancient story of the Po river features a tragic mythological race across the sky by the unlucky Phaethon.  In the story, Helio's son, Zeus, struck the chariot with a lightning bolt and the imprudent charioteer plunged into the river. 

Certainly, one of the most fascinating stories about the river is the Luigi Salvini’s story.  Luigi was a Slavic language universitary professor born in 1911. After the war [which war, World War II?], he established an independent republic on a small island in the middle of the Po river near Papozze. His republic had boundaries, passports and printed money whose value was only in a dreams. He shared information about his republic with other professors and friends who in this free island-state they were able to spend their summer holidays in nature, without rules except those of respect and mutual solidarity.

In the Po delta, Luigi Salvini met his passions: his wife, miss Matelda, daughter of the famous lyricist Luigi Catozzo, and the pristine landscape of the river - a beauty that would become known to others such as his many friends across Europe. During 1946 the World War II had just ended and had left destruction, missing and dead.  But liberation from war brought new energy. It [What is the "it" you are referring to? It just is not clear.] comes out of a long hibernation to "think" in freedom, and

Luigi Salvini with his determination built the Tamisiana Bosgattia republic, where man and nature are one. Till 1955 this small wild island became a sort of enclave. Visitors spent tiem on the island from July to September. Living in the Tamisiana Bosgattia republic didn’t mean ;laying around geting a sun tan.  Rather, the residents had to make feed themselves on the wildlife found on the island.  The day begin at dawn every morning, as the sun came out over the tops of the poplars.  The islanders set up the tasks to be accomplioshed each night.  tasks could include preparing the boat, reordering hooks and lines, examining the engine or such depending on whether the islander wanted to go fishing, explore the river, or get to the Adriatic sea.
In the Island there were no buildings, you lived in tents with gas fueled electric lights.  No reading, no radio, no news from outside this small word.  The happy site is a must see for tourists who come in dense swarms from near and far to visiting this community and admiring the happy life of its inhabitants.
