Final Answer:
I can help summarize the incident. Romulus and Remus, according to legend, were the twin brothers abandoned at birth and raised by a she-wolf. When Remus was kidnapped and brought before his great uncle Aemulius, the brothers were likely involved in activities related to the establishment of Rome, such as determining the site for the city's foundation or engaging in territorial disputes.
Explaination:
The story of Romulus and Remus is a foundational legend in Roman mythology, chronicled by various ancient historians like Livy. According to the legend, the brothers, having been raised by a she-wolf, grew up to establish the city of Rome. During their endeavors, Remus was captured and brought before his great uncle Aemulius. The specific activity they were engaged in at that moment isn't explicitly detailed in all historical accounts. However, given the narrative's context, it's presumed they were likely involved in the initial planning and territorial disputes that accompanied the establishment of Rome.
The circumstances surrounding Remus' capture and presentation before Aemulius are often depicted as a consequence of ongoing conflicts or disputes related to the founding of Rome. The legend, while rich in symbolic value, lacks precise historical details. Therefore, the activities Romulus and Remus were undertaking at the time of Remus' capture remain open to interpretation, with various artistic and historical adaptations portraying different scenarios of their actions leading up to that moment.
