He also wrote Series Principum qui Langobardorum aetate Salerni imperarunt... a vulgari anno 840 ad annum 1077.
Di Blasi made two trips through Italy, the first in 1754, the second in 1778, where he met and later communicated by missive with intellectual throughout the Italian peninsula including Girolamo Tiraboschi, Paolo Maria Paciaudi, Jacopo Facciolati, Giovanni Battista Passeri, and Anton Francesco Gori.
