Ictinus
Mid-5th-century BC Athenian architect

Ictinus 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.
“Ictinus” enters the record as mid-5th-century BC Athenian architect. Crown Archives preserves that source wording while asking what Ictinus, Mid-5th-century and Athenian can confirm, complicate or overturn.
Why this record matters
“Ictinus” is worth following because a concise public description often conceals a longer documentary argument. Here, Ictinus, Mid-5th-century and Athenian provides the most credible route into that argument.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Apr 27, 2026.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
