The literal meaning of translation in this context refers to a mathmatical function, the mapping of an object, using co-ordinates, from one location onto another. But it also evokes transportation and migration, the way peoples, cultures, traditions and objects have travelled - or been removed - from one place to another.

Like the cross-pollination that occurs when a bee flies from flower to flower, across gardens, hedges and fields, so as cultures and languages move and meet, they affect one another and new hybrids occur. But parts of the original meaning may well be lost. In every culture and language some elements remain untranslatable, perhaps only truly understood by natives in the original context.

At the beginning of the 21st Century, the cultural and political fallout from colonial times is still very much in evidence within both the colonised and the colonising cultures. Despite inequalities there is always a two-way influence. Just examine our food, our music, our sports and our language for evidence of the mixed bag that makes up 'Britishness'.

Simryn Gill is an artist of South Asian descent, born in Malaysia and now living in Australia. Much of her work centres on hybrid identities and the rich mix of influences from art, ecology and literature, to which she has been exposed.

Multicultural populations exist in virtually every city in the world. They have done for centuries. Overseas settlers have been coming to London for 15,000 years!
