ARTS / Competition: Win tickets and catalogues to the Royal Academy's show from the Ortiz collection

It is not often that the person behind an exhibition receives fan letters from the public, but George Ortiz, the collector whose ancient artefacts are pulling the crowds at the Royal Academy, has received over a dozen. Attendance figures at the exhibition are currently averaging 1,300 a day. To celebrate, the RA is offering five pairs of tickets and five catalogues to the first five Independent readers to answer the following three questions, set by Ortiz himself:

1. The two capitals of Sumeria were Lagash and Umma. In which country is Umma now?

2. How old was Alexander the Great when he died?

3. What is a tintinnabulum?

Answers on a postcard to Ortiz, Arts, The Independent, 40 City Rd, London EC1Y 2DB, no later than 15 March.
