Generate an image of Petra, Jordan, in the 1st century BCE, when it was a thriving trade hub. The iconic rock-cut structures of the city, especially the Treasury (Al-Khazneh), should be freshly carved and in pristine condition. The bustling city is filled with merchants, camels, and caravans, trading goods like spices, textiles, and incense. People are dressed in traditional Nabatean and Roman attire, engaging in trade and social activities. The surrounding rock formations are vibrant, with the reddish-pink sandstone glowing under the desert sun, and the atmosphere is lively, reflecting Petra’s prosperity.
