History of Real periods of genus 2 curves over $\mathbb{Q}$

 Title: Real periods of genus 2 curves over $\mathbb{Q}$-Definition: Let $C/\mathbb{Q}$ be a genus $2$ curve with Jacobian $A=\operatorname{Jac}(C)$,-  and let $\Lambda\subset\mathbb{C}^2$ be the period lattice obtained by integrating-  a canonical-sheaf basis over homology cycles. This table gives $\Omega_A=\#\pi_0(A(\mathbb{R}))\operatorname{covol}(\Lambda\cap\mathbb{R}^2)$,+Definition: Let $C/\mathbb{Q}$ be a genus $2$ curve with Jacobian $A=\operatorname{Jac}(C)$+  and period lattice $\Lambda$.
