The news of the Notamentis to the Repertoires leaves rather perplexed. Is said that in the '4oo Piano would have owned to Francis de Riccardis de Ortona, to which, for rebellion, king Ferrante would have removed it to give it in 1461 «to the university of Civita of Chieti »; donation then revoked by the king « for suis necessitatibus », and that is to resell the castle of Piano to Giovanni d'Afflitto not of the family of Rodio but the D'Afflitto of Loreto and Trivento.

We could suppose, therefore, an error of the official that transcribed to the voice Piano of Principality the purchase served as the count of Trivento of a homonym hamlet of Abbruzzo, also because the adjoining village of Vetrale seems that had been purchased by Giacomo Ros, together with Vietri and Vatolla. However in 1614 also Piano was sold by the Pignatellis to Giacomo Zattara and in the 1648 sister Angela Ferrara surrendered Piano to the female monastery of the civil jurisdiction of Gioi.

By the «Refute » results that the hamlet in 1770 passed from G. Baptist Pasca to Nicola de Marco and this also finds confirmation in the Cedolaris.

Subsequently it passed to the regal curia with « jurisdiction in suspended » as also notices Giustiniani that wrote at the beginning of 800. The same source notices the characteristics of the local production that it primarily consisted in « wheat, wine, oil and chestnut trees and oaks ». From the 1808 budget we learn that mayor of the time was Felice Gugliucci.

News contained in the Notamentis to the Repertoires concerning Vetrale are more reliable than those pertaining to Piano Vetrale, that with Vietri and Vatolla would be granted to Giacomo Ros, to whose death, for lack of heirs, would have been summoned by the Crown, that sold them in 1562, with the ritual clause of ransom, to Elizabeth Pica.This would have surrendered in turn the right to Ettore Caracciolo, that entered possession of the hamlets after having poured the amount to F. Porcinario.

This is indirectly confirmed by the fact that king Alfonso of Aragon in 1451 granted the mixed imperio as well as the penal jurisdiction of Eredita and Gioi to Massimo Caracciolo, privilege that according to the document contained in the above-mentioned Notamentis was preserved from the descendants. In fact in the 1729 Luca Caracciolo sold the jurisdiction of Salella to Stefano Maresca. In an action of donation of 3 July 1648 of the notary F. Riccio is news of the transfer from the heir of the barons Ferrara to the female monastery of Gioi of civil jurisdiction of Vetrale.

In 1770, as is inferred by the Refute and by the Cedolaris, the hamlet passed from G. Baptist Pasva to Nicola de Marco.Galanti, therefore, informs that the two hamlets had passed to the regal curia (they are in suspended jurisdiction) and that had not been alienated to the beginning of 800, as Giustiniani said. He describes the village « built in mountainous place, where you can breathe good air and the inhabitants are all employees to the agriculture, that represented the prevailing occupations of the populations of the Cilento.

In the file of Salerno there are only the protocols of a notary of the place and precisely of Evangelist de Matteis that operated in the decade 1722 - 1732. In 1808, before the aggregation of the village to Orria, was mayor of Vetrale Nicola Sica.
