What is the difficulty level of sentence: "Sicilian fertility, which had been everywhere famous,

was given the lie when the crops died as they sprouted,

now ruined by too much heat, and now by too heavy a rainfall;

stars and winds harmed them, and the greedy birds devoured

the seed as it was sown; the harvest of wheat was defeated

by thorns and darnels and unappeasable grasses."?
