Will no one take up Drawingboard's challenge? Right then:
1. Nicholas Hawksmoor, post-Wren, when he was building amazing doom-laden London churches. Was he as much of a curmudgeon as he was painted? Brighten up, Nick!
2. Inigo Jones, early Jacobean, just back from his Italian tour of Palladio buildings. Any new ideas for London, Inigo?
3. Frank Lloyd Wright, half-way through the building of Fallingwater. Still on time and budget, Frank?
4. Edwin Lutyens, in New Delhi. Do you reckon British rule will ever end, Ned?
5. Michael Scott bumping into James Joyce down at Sandycove (is this chronologically possible?)
6. Richard Rogers and Norman Foster designing their (now demolished) proto high-tech Reliance Controls building, Swindon. So, you two: do you ever fall out over anything?
7. Joseph Paxton making the Crystal Palace, 1851.What on earth are you going to do with this white elephant when the show's over, Joe?
8. Decimus Burton and engineer Richard Turner sketching out the Palm House at Kew, 1840s. Not much ornament there, Decimus.
9. Callicrates at the Parthenon. Exactly how is this meant to be democratic, Cal?
10. Le Corbusier at the first client meeting for Ronchamp Chapel. No need to ask anything - he wouldn't listen anyway.
