Step-by-step explanation:
Analyzing the imagery, "They lay calm-breathing, on the bedded grass; / Their arms embraced, and their pinions too," we can deduce that it suggests a harmonious and intimate connection. The descriptors such as 'calm-breathing' and 'bedded grass' evoke a sense of peace and tranquility, while 'embraced' and 'pinions too' imply a close, maybe even protective, togetherness. This imagery is rich with connotations of warmth and affection, contrasting significantly with tension, conflict, or aggression.
