Sylvanus deus est silvarum. Hic amavit puerum Cyparissum nomine qui habebat mansuetissimam cervam. Hanc cum Silvanus nescius occidisset, puer extinctus est dolore. Quem amator deus in cypressum arborem nominis eius convertit quam pro solatio portare dicitur.
--Vatican Mythographers I.6
Sylvanus was the god of the forest. He loved a youth (puer) named Cyparissus who had a pet doe. When Sylvanus unintentionally killed it, Cyparissus died of grief. Silvanus transformed him into a cypress tree and is said to carry its branches as a mourning token.
