(label) Given a diagram F'' : ''J'' → ''C'', a ''cone'' consists of an object ''N'' of ''C'', together with a family of morphisms ψ_''X'' : ''N'' → ''F''(''X'') indexed by all of the objects of ''J'', such that for every morphism ''f'' : ''X'' → ''Y'' in ''J'', $F(f)\; \backslash circ\; \backslash psi\_X\; =\; \backslash psi\_Y$. Then ''N'' is the ''vertex'' of the ''cone'', whose ''sides'' are all the ψ_''X'' indexed by Ob(''J'') and whose ''base'' is ''F''. The ''cone'' is said to be "from ''N'' to ''F''" and can be denoted as (''N , ψ).

«Let J'' be an index category which has an initial object ''I''. Let ''F'' be a diagram of type ''J'' in ''C''. Then category ''C'' contains a cone from ''F''(''I'') to ''F .»
