Triglav is the highest mountain of Slovenia, and its image is on both the country’s coat of arms and national flag. It shares it name, and is perhaps named after, the Slavic three faced god / unity of gods.
The three headed trinity of Triglav is said to watch over the upper, middle and lower realms of existence. He is a god who constantly looks back into the past, studies the present and gazes into the future.
I am unable to find an graphical image but he has is described as a three-headed man sometimes wearing a golden veil or blindfolds over his eyes, or a man with three goat heads.
