Rule reminder
In literary and formal Italian, the present participle (participio presente) can form absolute constructions expressing a state or action simultaneous with the main event: 'Gli occhi splendenti di lacrime, tacque.' (His eyes shining with tears, he fell silent.) Unlike the past-participle absolute (which marks completed prior action), the present-participle absolute expresses simultaneity. This construction is archaic or literary in tone — it appears in 19th- and 20th-century novels, poetry, and high-register prose, but rarely in everyday speech. The present participle agrees in gender and number with its own nominal subject.
