Question: How old would Artaxias IV have been when Nobles petitioned Bahram V to depose him? Passage 1:The «Nikos Kazantzakis» Stadium (), formerly known as Ergotelis Stadium and more commonly as Martinengo Stadium, is a football stadium located on the Martinengo bastion, part of the fortifications of Heraklion, on the island of Crete. It is named after Modern Greek literature giant Nikos Kazantzakis, whose grave is also located on the same bastion. It is part of the Ergotelis Athletic Centre, a sport facilities complex owned by Greek multi-sport club Ergotelis. Built in 1946, as Ergotelis Stadium (), it was the traditional home ground of Greek football club Ergotelis until 2004, when the club moved to the Pankritio Stadium, Heraklion's largest and most modern sports venue. The complex currently houses the Ergotelis Youth Academy, the largest youth sports academy on the island of Crete, and one of the largest in Greece, while the stadium itself is still used as the home ground of multiple Heraklion football clubs playing in the Heraklion Football Clubs Association amateur league system. It has a capacity of about 1,000 spectators, of which approximately 600 can be seated.

After service as the Deputy Assistant Adjutant General (DAAG) for Dublin and Aldershot Districts, he was in January 1900 appointed Deputy Assistant Adjutant General for the 8th Division South African field force, created to take part in the Second Boer War in South Africa. He left Southampton in the SS Moor in March 1900 with the staff of the 8th division and 600 men of militia regiments, arriving in Cape Town the next month. In South Africa, he took part in operations about Dewetsdorp and Thabanchu during the relief of Wepener (April 1900), the occupation at Senechal, and the action at Biddulphsberg (May 1900). He was DAAG for intelligence during the operations in the Wittebergen and Nordebergen, resulting in the surrender of Boer Commandant Prisloo in July 1900. Later that year he took part in the occupation of Harrismith and the action at Doornberg (Sep 1900) where he was wounded, then served for the duration of the war in the Orange River Colony.

 Passage 3:The Kingdom of Armenia under the Arsacid dynasty of Armenia was the first nation to officially convert to Christianity, in 301 AD under Tiridates III. In 428, Armenian nobles petitioned Bahram V to depose Artaxias IV (Artashir IV). As a result, the country became a Sassanid dependency with a Sassanid governor. The Armenian nobles initially welcomed Persian rule, provided they were allowed to practise Christianity; but Yazdegerd II, concerned that the Armenian Church was hierarchically dependent on the Latin- and Greek-speaking Christian Church (aligned with Rome and Constantinople rather than the Aramaic-speaking & Persian-backed Church of the East) tried to compel the Armenian Church to abandon Rome and Byzantium in favour of the Church of the East or simply convert to Zoroastrianism. He summoned the leading Armenian nobles to Ctesiphon, and pressured them into cutting their ties with the Orthodox Church as he had intended. Yazdegerd II himself was a Zoroastrian rather than a Christian, and his concern was not religious but securing political loyalty.
