	abstract = {We present a rest-frame UV-optical stacked spectrum representative of quiescent galaxies at \$1.0 {\textless} z {\textless} 1.3\$ with log\$(M\_*/{\textbackslash}rm\{M\_{\textbackslash}odot\}) {\textgreater} 10.8\$. The stack is constructed using VANDELS survey data, combined with new KMOS observations. We apply two independent full-spectral-fitting approaches, obtaining consistent stellar ages and metallicities. We measure a total metallicity, [Z/H] = \$-0.13{\textbackslash}pm0.08\$, and an iron abundance, [Fe/H] = \$-0.18{\textbackslash}pm0.08\$, representing falls of \${\textbackslash}sim0.3\$ dex and \${\textbackslash}sim0.15\$ dex respectively compared with the local Universe. We also measure the alpha enhancement via the magnesium abundance, obtaining [Mg/Fe] = 0.23\${\textbackslash}pm\$0.12, consistent with similar-mass galaxies in the local Universe, indicating no evolution in the average alpha enhancement of log\$(M\_*/{\textbackslash}rm\{M\_{\textbackslash}odot\}) {\textbackslash}sim 11\$ quiescent galaxies over the last 8 Gyr. This suggests the very high alpha enhancements recently reported for several very bright \$z{\textbackslash}sim1-2\$ quiescent galaxies are due to their extreme masses, in accordance with the well-known downsizing trend, rather than being typical of the \$zrsim1\$ population. The metallicity evolution we observe with redshift (falling [Z/H], [Fe/H], but constant [Mg/Fe]) is consistent with recent studies. We recover a mean stellar age of \$2.5{\textasciicircum}\{+0.6\}\_\{-0.4\}\$ Gyr, corresponding to a formation redshift, \$z\_{\textbackslash}rm\{form\} = 2.4{\textasciicircum}\{+0.6\}\_\{-0.3\}\$. Recent studies have obtained varying average formation redshifts for \$zrsim1\$ massive quiescent galaxies, and, as these studies report consistent metallicities, we identify different star-formation-history models as the most likely cause. Larger spectroscopic samples from upcoming ground-based instruments will provide precise constraints on ages and metallicities at \$zrsim1\$. Combining these with precise \$z{\textgreater}2\$ quiescent-galaxy stellar-mass functions from JWST will provide an independent test of formation redshifts from spectral fitting.},
