Red is the color of Blood Birth and sacrifice. The most powerful color of all.

The Emperor Of Rome wore red to Show his Divinity.
All the generals of war wore red to show their power as the right hand of the Emperor.
In his name they bring life or death.
As a door it means a powerful place of death and the promise of rebirth.

Red flowers like the rose. Where given to a woman to show her undying love.
Also that you would kill or die for her.
Taken for granted by young men today!
I could go on and on about the power of red. LOL

Unfortunately You can tell her. It is very hard to make a living on
graveyard shots. As a hobby it is fine however. I love it.
But using them as a background for art writing illustrations or manipulation is well worth it.

As to the vessel... that I would have to see.
Most religions gave sacrifices of Water or Wine Perfume Oils Candles Flowers Food and Incenses.
Some containers where used in the past to hold oil to light while in the tomb.
A prime example of this is New Orleans. Where I am from.

One day of the year on all Hollows Eve (Halloween) the living commute with the dead.
The people of New Orleans wash the family tombs. Put fresh flowers candles food wine
and burn incenses. This is the day of the dead. It is thought at this time the dead are
given the chance to commute with the living.

Hope this helps my friend.
Anything else let me know.
Blessed Be
RED

Hi Red, I promised my neice I would ask you some questions. She is obsessed with photographing cemetaries. She asked me a couple questions I thought maybe you could answer with all the knowledge you seem to have of such things. Why are Church doors usually painted red? What did they do with the things almost shapped like craddles or a bathtub on the back of tumbstones. Might have to send picture as I know that discription was lacking to say the least. They are above the place where the person would be laying. Did they fill them with flowers? Just to keep people from walking on them or some kind of other reason placed there in tradition? Gosh she had other questions too. Well, if you can answer those that would be cool.
