[1] Pacorus II's name is recorded in the bilingual inscription on the famous bronze statue of Heracles in Seleucia as Greek Pakhorou (Παχόρου, genitive) and Parthian pkwr (𐭐𐭊𐭅𐭓 'Pakur').

[12][11] Artabanus III initially agreed to lend military aid to Terentius Maximus to capture Rome, until he found about the real identity of the impostor.

[11] Like his father, Pacorus sought to accomplish the goal of Artabanus II (r. 12–38/41), by attempting to establish a long and structured trade-route that spanned through East Asia, India and the coast of the Mediterranean Sea.

[8] In order to accomplish this, Pacorus strengthened relations with other powers whom he was able to establish long distance trade with, most notably Han China.

[13] In 97, the Chinese general Ban Chao, the Protector-General of the Western Regions, sent his emissary Gan Ying on a diplomatic mission to reach the Roman Empire.

[14] He traveled as far west as the Persian Gulf, where the Parthian authorities convinced him that an arduous sea voyage around the Arabian Peninsula was the only means to reach Rome.

[17] The modern historian William Watson speculated that the Parthians would have been relieved at the failed efforts by the Han Empire to open diplomatic relations with Rome, especially after Ban Chao's military victories against the Xiongnu in eastern Central Asia.

[21] At first, he appeared beardless on his coins, a rare feature in Parthian coinage that demonstrated his youth, having ascended the throne around the age of sixteen or seventeen.

[21] The modern historian Marek Jan Olbrycht surmises that the wearing of the tiara in the latter part of his reign was reflected the power and status of his empire at this time.
