     Let $L / K$ be a field extension and let $\cH(T)$ be the algebraic closure in $L$ of the subfield of $L$ generated by $K$ and $T$.\footnote{This is the intersection of all subfields of $L$ containing $K \cup T$, or the field of quotients of the sub-$K$-algebra of  $L$ generated by $T$.}
     Then $\cH$ is a matroidal hull operator.

+\begin{proof}
     H1, H2 and F are trivial. For an algebraically closed subfield $K \se M \se L$ we have $\cH(M) = M$. Thus $\cH(\cH(T)) = \cH(T)$ (H3).
 
     Let $x,y \in L$, $T \se L$ and $x \in  \cH(T \cup \{y\}) \sm \cH(T)$. We have to show that $y \in  \cH(T \cup \{x\}) \sm \cH(T)$.
