- Dii is also the plural of Latin Deus.
The Dii (//; Ancient Greek: Δίοι) were an independent Thracian tribe, swordsmen, who lived among the foothills of Mount Rhodope in Thrace, and particularly in the east bank of Nestos, from the springs to the Nestos gorge. They often joined the ranks of organized armies as mercenaries or volunteers. Thucydides declared that they were the most warlike infantry in Sitalkes' army.
The Legend of Diyes is an interesting legend about the Dii.
