How the Celtic festival that marked the beginning of Winter became All Hallows is not clear. Some say the Church set up its own festival independent of the Northern European traditions. But it is as likely that the Church adopted existing pagan festivals, and gave them a Christian spin.
Samhain, on October 31st, was, for Celtic religions, not only the beginning of Winter but also the beginning of the Year. As I noted on my Halloween post the Festivities began in the evening before the day because Celtic and Germanic traditions began their day at Dusk. So Halloween is not, in fact, the evening before, it is the start of the day of the festival.
The Church adopted the Roman tradition of the day beginning not at Dusk but at Midnight. So the festival of All Hallows is on November 1st not October 31st. But the Church mimicked the old ways of doing things by celebrating the evening before as the Vigil of All Hallows’ Day. This was called All Hallows Evening or Halloween.
All Hallows by the Tower, London
In London, there is a Church called All Hallows, on Tower Hill. It is associated with Barking Abbey, founded in the 9th Century. Therefore, it is known as All Hallows Barking or All Hallows by the Tower. The Church has a prominent position on Tower Hill, which would have been visible from boats coming up the Thames. Also in the Church is the earliest Post-Roman arch in a Church in the City of London. This is made of reused Roman bricks. Moreover, in the crypt are Roman tessellated floors.
Now, I don’t want to be shot down in flames because there is no evidence that there was a Roman Temple here. Nor indeed a Roman or immediately Post-Roman Church. But it is one of the earliest Churches in the City of London. There must have been Christian Churches in Roman London, and this would be on my list of candidates. It is simply that the attribution to All Hallows provides a possible link to Celtic festivals. So speculation rather than anything else. The letter above, gives a context for the conversion of a pagan Temple to a Christian Place of Worship.
An Uncanny Day to Hallowed Day
For the Celts, Samhain was an uncanny day when all the sprites and spirits are alive and in the world. The Church took that, and span in on its head. So it became a ‘hallowed’ holy day when all Saints are celebrated and alive to us. Celebrated on October 31st and November 1st.
A celebration of All Saints was originally in May in the Church but was changed to the 1st November in the 7th Century by Pope Boniface. Later it was swapped back to May. But fixed again on the 1st November in the 9th Century. It is followed on the 2nd by All Souls’ Day. (see my post on All Souls Day here.
So on the 1st November, those celebrating the pagan festival would be in full swing after a hard night of celebration. The embers of the Fire would be still burning, stones left around the fire would be inspected for the prophecy they told of the future. Each person had a stone, and if it was still intact it was good luck, if it had disappeared the future was not good.
La Toussaint et Dia de Todo Los Santos
In France, All Hallows or All Saints is called La Toussaint, and flowers such as Chrysanthemums, which blossom in late October, were put on the graves. In Spain, it is Dia de Todo Los Santos and is a national holiday upon which people put flowers on the graves of the dead.
In Mexico, Dia de los Muertos celebrates Holy Innocents on the 1st. People create altars to the lost ones, with their favourite flowers, toys, food stuffs,, photographs. People argue about the pre-colombian aspects of the festival as there are similarities to European All Saints Days celebrations. But Quecholli, was a celebration of the dead that honoured Mixcóatl – the god of war. It was celebrated between October 20th and November 8th.
A correspondent in Mexico has sent back these pictures of the festivities in Mexico.

A Day Off for the English
In the Laws of King Alfred the Great, this day was a day off for freemen. See my post on Days off in the Anglo Saxon Calender on August 15th.
