WHO worshipped what and were their beliefs compatible? That is the basis of a talk by Professor Miranda Aldhouse-Green that signals the start of a Museums and Galleries month in May.

To celebrate, the Roman Legionary Museum at Caerleon is putting on an evening lecture on May 4 by Professor Aldhouse-Green from the University of Newport. Her subject will be 'The Gods of Roman Wales.'

Its focus is the archaeology of religion and ritual during the Roman occupation of Wales during the fourth century AD.

Professor Aldhouse-Green will look at native British cults in Wales, intrusive Roman religion brought in by the Roman army, merchants and other foreigners, and the interaction between these two systems which gave rise to a new type of Romano-British religion.

Wales experienced more of its share of interesting finds on this subject and such an example of 'composite deity' was said to have been found in a temple dedicated to Mars-Oculus at Caerwent, and a stone head dating from 300AD found at Caerleon suggests that native British beliefs continued unhindered without having to combine with Roman practices.

Professor Aldhouse-Green's lecture will be accompanied by a British sign language interpreter to enable deaf or those hard of hearing to enjoy it. Museum manager Bethan Lewis said: "We try to make the museum as accessible as possible and this is just one way we can improve our service.

"We are more than happy to help any group with access requirements to enjoy their visit here. People just need to tell us what they want and we will try our best to provide it."

The Roman Legionary Museum is also home to the south east Wales branch of the Young Archaeologists Club, a dedicated band of eight to 16-year-olds with a passion for history and archaeology.

The club is staffed entirely by volunteers who take members on a different historical adventure each month.

The club is celebrating its tenth birthday this year and will be holding a day packed with archaeological activities at the museum, many run by club members.

Tickets to Professor Aldhouse-Green's lecture on May 4 are £3 and are available from the museum.

The YAC tenth birthday event takes place on the following Saturday and is free.
