We relate the relative nerve $N_f(D)$ of a diagram of simplicial sets $f : D \to sSet$ with the Grothendieck construction $Gr F$ of a simplicial functor $F : D \to sCat$ in the case where $f = N F$. We further show that any strict monoidal simplicial category $C$ gives rise to a functor $C^\bullet : \Delta^\op \to sCat$, and that the relative nerve of $\N C^\bullet$ is the operadic nerve $\N^\otimes(C)$. Finally, we show that all the above constructions commute with appropriately defined opposite functors.
Keywords: simplicial categories, Grothendieck construction, higher category theory, operads
