                      electron lasers (XFELs) involve rapidly evolving conditions
                      of temperature. Here,we report time-resolved, direct
                      measurements of temperature using spectral streaked optical
                      pyrometry of x-ray and optical laser-heatedstates at the
                      High Energy Density instrument of the European XFEL. This
                      collection of typical experiments, coupled with
                      numericalmodels, outlines the reliability, precision, and
                      meaning of time dependent temperature measurements using
                      optical emission at XFELsources. Dynamic temperatures above
                      1500 K are measured continuously from spectrally- and
                      temporally-resolved thermal emission at 450–850 nm, with
                      time resolution down to 10–100 ns for 1–200 μs streak
                      camera windows, using single shot and integrated
                      modes.Targets include zero-pressure foils free-standing in
                      air and in vacuo, and high-pressure samples compressed in
                      diamond anvil cell multi-layer targets. Radiation sources
                      used are 20-fs hard x-ray laser pulses at 17.8 keV, in
                      single pulses or 2.26 MHz pulse trains of up to 30pulses,
                      and 250-ns infrared laser single pulses. A range of further
                      possibilities for optical measurements of visible light in
                      x-ray laserexperiments using streak optical spectroscopy are
                      also explored, including for the study of x-ray induced
                      optical fluorescence, whichoften appears as background in
                      thermal radiation measurements. We establish several
                      scenarios where combined emissions from multiplesources are
                      observed and discuss their interpretation. Challenges posed
                      by using x-ray lasers as non-invasive probes of the sample
