I'm glad to note that Giulia Visintin took the proverb as I did. The proverb ldoes indeed look very Sardinian in form and syntax. One sees this from 'andet' which is a regularly formed present hortatory subjunctive in the logudorese dialect. The problem however is that Sardinian dialects show a bewildering richness of phonetic variation from town to town. 'isculzu' looks like the form registered for inland, central dialects there, iskultsu/iskurtsu. In logudorese one would expect 'skurtsu'. Again, 'ispinaza' evidently corresponds to 'Italian 'spina' (thorn, prickle'), with what looks like a Spanish suffixal variation on ispinattu, which however in northern logudorese means 'hackle' in the trade jargon of weaving, a steel flax-comb, though to complicate things 'ispinattsu' can indeed mean 'spinach'. Contextually the sense however is thorn.
