Herbert I (died 13 April 1035), called Wakedog (from French Eveille-chien, Latinized as Evigilans Canis), was the count of Maine from 1017 until his death.
[3] From the time Herbert became count in 1017, he was almost constantly at war with Avesgaud de Bellême, Bishop of Le Mans.
[6] Odo’s greater force was prevailing and Fulk himself was thrown from his horse and in danger of being killed or captured, but a messenger had been sent to Herbert to come immediately.
[14] While plain coins with only Latin motto Gratia dei rex had been minted under comital authority throughout the tenth century at Le Mans, at some time between 1020 and 1030 coins were struck with the monogram of Count Herbert and the motto signum Dei vivi and continued with this design through the twelfth century.
The coins at Le Mans were of such weight and fine quality they were among the most widely accepted in western France.
