Mount Athos weathered lithography (icon) of the Holy Trinity in pine wood with carved decoration.

The Holy Trinity is one of the main doctrines accepted by the Orthodox Christianity and refers to the belief in a triune God. The three persons of the Holy Trinity are the Father, the Son and the Holy Spirit, who are identical, indivisible and co-essential in divinity. The Holy Trinity is also depicted in the Hospitality of Abraham in the form of three angels.
