Problem: Please answer a question about the following article about Pope Paul VI:
Paul VI revolutionized papal elections by ordering that only cardinals below the age of eighty might participate in future conclaves. In Ecclesiae Sanctae, his motu proprio of 6 August 1966, he further invited all bishops to offer their retirement to the pontiff no later than the completion of their 75th year of age. This requirement was extended to all Cardinals of the Catholic Church on 21 November 1970. With these two stipulations, the Pope filled several positions with younger bishops and cardinals, and further internationalized the Roman Curia in light of several resignations due to age.
When was Paul Vi's Ecclesiae Sanctae issued?
A: 1966

Problem: Roman camps followed a standard pattern for defense and religious ritual; in effect they were Rome in miniature. The commander's headquarters stood at the centre; he took the auspices on a dais in front. A small building behind housed the legionary standards, the divine images used in religious rites and in the Imperial era, the image of the ruling emperor. In one camp, this shrine is even called Capitolium. The most important camp-offering appears to have been the suovetaurilia performed before a major, set battle. A ram, a boar and a bull were ritually garlanded, led around the outer perimeter of the camp (a lustratio exercitus) and in through a gate, then sacrificed: Trajan's column shows three such events from his Dacian wars. The perimeter procession and sacrifice suggest the entire camp as a divine templum; all within are purified and protected.
Of what were Roman camps diminutive versions?
The answer is the following: Rome
