7.2 Italy suffers from the drought

Between Campania, Sienna, Florence and Tuscany,
it will not rain a drop for six months and nine days.
A foreign language will be spoken in Dalmatia,
it will overrun the country, devastating all the land. (II-84)



This refers to the time of troubles. The drought refers to the weather changes that will be taking place in relation to the earth changes at the time. «The foreign language being spoken and overrunning the land» refers to the Anti-Christ’s forces taking over Italy and, as mentioned before, Greece, by destroying the cultural centers to help destroy the morale.
Those city names are just representative of that part of Europe where the drought will occur, particularly in Italy. (see IV-60, 6.4)
