Angelo (not Antonio) lives in the house of the mentioned (maybe in the previous page) Antonio Saulini (or Sacchini) and pays to him 25 carlini every year.
Angelo has a land in a place called La Vigna della Corte near Giuseppe Maddalena and Giuseppe Corno(!), with vines, fig-trees, trees fruit; this land yelds (gives a profit of?) 15 carlini per year, but it's burden with a tax of 10 carlini in favour of the Camera Ducale of Montalto. So Angelo is considered to have a value of 5 once from this land and 12 once from his work: for this "income" he must pay once 3 and carlini 1 (one is written in letters, but in numbers it appears to be 10!).
I'm not able to decipher how is obtained the result (13 once and 20 carlini).
This link is in italian, but i think that can help you to understand what is a catasto onciario: www.fasf.uniba.it/area...ciario.pdf
