Well, here it is on the right side of Washington Square’s Saints Peter and Paul Church in the North Beach.
Take a look for yourself on MapJack – this famous church is San Francisco Hot Spot #7.

Here’s a stab at it:
I saw a windstorm coming out of the north – an immense cloud with flashing lightning and surrounded by brilliant light. The centre of the fire looked like glowing metal, and in the fire were what looked like four living creatures. Each of them had four faces and four wings …
Their faces looked like this: Each of the four had the face of a man, and on the right side the face of a lion, and on the left the face of an ox; each also had the face of an eagle. Such were their faces …
Then there came a voice from above the expanse over the heads of the living creatures as they stood with lowered wings. Over their heads was what looked like a throne of sapphire, and high above on the throne was a figure like that of a man …
This was the appearance of the likeness of the glory of the Lord.
Ezekiel 1:4-5,10-11, 25-26, 28.
But, as always, You Make The Call.
[UPDATE]: We have what looks like a winner here: “Actually that’s an ox, and he symbolizes St. Luke–the other three figures on the facade of the church symbolize the other three Evangelists: Matthew (An angel), Mark (A lion), and John (An eagle)”
