Example 8.4.2.6. Let $\operatorname{\mathcal{C}}$ be a locally small category. Then the evaluation profunctor
\[ \operatorname{ev}: \operatorname{\mathcal{C}}^{\operatorname{op}} \times \operatorname{Fun}( \operatorname{\mathcal{C}}^{\operatorname{op}}, \operatorname{\mathcal{S}}) \rightarrow \operatorname{\mathcal{S}}\quad \quad (X, \mathscr {F}) \mapsto \mathscr {F}(X) \]
is corepresentable by the covariant Yoneda embedding $h_{\bullet }: \operatorname{\mathcal{C}}\rightarrow \operatorname{Fun}( \operatorname{\mathcal{C}}^{\operatorname{op}}, \operatorname{\mathcal{S}})$.
