According to legend, many Portuguese people would attach the following poem to trees in their forests:

Ye who passes by and would raise your hand against me, harken ‘ere you harm me.

I am the heat of your hearth on the cold winter nights, the friendly shade screening you from summer sun, and my fruits are refreshing, quenching your thirst as you journey on. 

I am the beam that holds your house, the board of your table, the bed on which you lie, the timber that builds your boat.

I am the handle of your hoe, the door of your homestead, the wood of your cradle, and the shell of your coffin. 

I am the bread of kindness and the flower of beauty. 

Ye who pass by, listen to my prayer, harm me not.
