Trasimeno. This is the name of the lake of Perugia, which comes from its geographical location: over the mount Imeno (or Menio), its pre-roman name, which delimits it at south.
Agello is a part of Magione, right near the lake. The name Agellus is often used to give name to the lands born over farm fields.
Nevertheless, the Trasimenide, an ancient legend written from Matteo dall'Isola in book I, verses 156-166, already mentioned in 16th Century, gives us an alternative origin of the place name’s and also narrates a wonderful story.
The nymph Agilla (or Egille) had dwelling on the Isle Polvese, in the middle of the lake, and from time to time she found there hunting the Prince Trasimeno, son of the Etruscan God Tirreno.
The Prince, attracted from her singing, arrived at her home, and when he saw her beauty he felt ill-at-ease. He introduced himself to her timidly, pretending to be a fisher whose boat was overturned near the island, and she fell deeply in love with him.
After long chats and moments when the nymph sang to Trasimeno, he confessed who he really was and asked her to marry him. Soon they married with the blessing of the God and father Tirreno (which initially was contrary to this marriage).
In the following days the two lovers lived a happy life, one near the other; then one day, when Trasimeno went to swim in the lake, he sank and never came back.
The bride, desperate to find his husband, began a draining search all over the lake, looking into boats and houses until one day, since she forgot even to eat, she lied on a boat and died.
The legend says that when the wind blows between the branches of the trees of the Island Polvese, one can hear the heartbreaking wailing of the nymph Agilla, daughter of the Sun, still looking for her husband, the beautiful son of Tirreno, and when the biggest waves overturn the boats is because she thinks she found him after centuries of search.
But the waters never brought back to her his husband, vanished like a drop of water among the others, as if the water of the lake not only yearn for his body, but for his name too.
