You can spot the "Angel" or her absence in many classic texts:

The true genius of the angel as a social construct lies in its inversion of power. It presents submission as moral superiority. The domestic sphere, where the angel reigned, was recast not as a retreat from the grimy, competitive male world of commerce and politics, but as its moral and spiritual heart. The angel’s weakness—her emotionality, her fragility, her “innocence”—was paradoxically her strength. She was the repository of all the values that would be crushed in the market: compassion, piety, tenderness. This conferred upon her a sacrosanct status, a pedestal of purity. But a pedestal is also a prison. While the angel was worshipped for her moral purity, she was also stripped of legal and economic agency. She could not vote, own property independently, or enter into contracts. Her reward for being an angel was a gilded cage of dependency. The pedestal kept her elevated, but also kept her contained, silent, and powerless to change her circumstances.
