or

2. Gormley’s artwork One and Other paved the road for Creed’s Work No.850.

or

3. Creed’s Work No.850 and Gormley’s artwork One and Other are interlocutors for each other, just as Gormley’s One and Other and his own 2007 installation Event Horizon are also interlocutors for each other.

Context:

To pursue the conversation on triangulated conversations, Creed’s Work No.850 seems also to shout down the road to Gormley’s artwork One and Other– mentioned earlier – for Trafalgar Square’s fourth plinth in both its durational and time-based aspects: a prolonged series of short-lived, living portraits or performances, involving a controlled regime of rotating, signed-up members of the public. Where Creed’s work takes risks in giving licence to an act normally prohibited within the day-to-day functioning of the museum – one which could lead to collisions and injury, for example – Gormley’s also seeks to challenge an ever-growing, stultifying tendency to take measures to guarantee personal health and safety at all costs.

Gormley’s plinth – upcoming at the time of writing – which effectively will have offered members of the public the opportunity for just one hour to ‘perform their own space’ in the city – to take themselves outside of themselves or be both ‘one and other’ – seems, in turn, to act as a playful interlocutor for his own major 2007 installation Event Horizon over the river at the Hayward art gallery.
