According to the autobiographic "La Vita Nuova", Beatrice and Dante met only twice during their lives. Even less credible is the numerology behind these encounters, marking out Dante's life in periods of nine years. This amount of time falls in line with Dante's repeated use of the number three or multiples of, derived from the Holy Trinity. It is more likely that the encounters with Beatrice that Dante writes of are the two that fulfill his poetic vision, and Beatrice, like Petrarch's Laura, seem to blur the line between an actual love interest and a means employed by the poet in his creations.
