You may be most familiar with the larger version of me, But I can assure you, that I can also be goat-like when seen With my mounted spear and cloven hooves, I delicately pick my way through the forest, My spear highly sought to cleanse and heal Fleet of foot, I flee from those no longer innocent in a sense I am beauty, I am grace, And leave practically no trace Do you know who I am?
