Hyacinth Louis Rabino di Borgomale (1877-1950) was a professional diplomat who spent many years in Persia in a variety of consular posts, first in Kirmanshah and particularly at Rasht, where he served as vice consul from 1906 to 1912. He was then posted to the Arab world (first Morocco and ultimately to Cairo, via Smyrna and Salonika), but retained his interest in the Caspian provinces. Alongside Mazandaran and Astarabad his other significant publications are his edition of the Ta ri kh-i Gi la n va Dailamista n by Zahir al-Din Mar'ashi (1912) and Les provinces Caspiennes de la Perse: Le Guilan (1917).
