Ictinus

Ictinus (; , Iktinos) was an architect active in the mid 5th century BC. Ancient sources identify Ictinus and Callicrates as co-architects of the Parthenon. He co-wrote a book on the project – which is now lost – in collaboration with Carpion.

Pausanias identifies Ictinus as architect of the Temple of Apollo at Bassae.

Pericles also commissioned Ictinus to design the Telesterion ("Hall of Final Things") at Eleusis, but his involvement was terminated when Pericles fell from power. Three other architects took over instead.

The artist Jean Auguste Dominique Ingres painted a scene showing Ictinus together with the lyric poet Pindar. The painting is known as Pindar and Ictinus and is exhibited at the National Gallery, London.
