Friedrich August Schulze, Terrible Tales (1891)
“ After they had exhausted the power of words in reciprocal protestations and vows, Felippo invoked the avenging powers to bring destruction on his own head if he should be unfaithful, and wished that his intended bride should not even find rest in her grave if he deserted her, but follow him still to claim his love. When these words were uttered, the lovers and Clara’s parents sat at table, and to such an extent did the young couple carry their enthusiasm that they both wounded themselves in the left arm and mingled their blood in a glass of white champagne. ”
