In the eighth year of his reign, Lamperius was pricked by a rosebush in the imperial pleasure gardens. He ordered the bush chopped down but a hummingbird dwelling within it attacked the gardeners and the guards so fiercely that the Emperor relented and instead had the garden paths rerouted. This would normally mark Lamperius among the enlightened Emperors had he not then ordered the guards put to death on the principle that if they could not defend him from either a stationary rosebush or a bird the size of a moth, they were clearly incompetent to defend the royal person from actual threats.
